#1 Landbot

Barcelona, Spain Founded 2015 Free (100 chats/month, 1 seat) / Starter EUR 32 per month / Professional EUR 80 per month / Professional WhatsApp EUR 160 per month / Business from EUR 400 per month; extra chats EUR 0.05 each Free plan; 14-day trial on paid plans, no card required

Best for: Marketing teams designing lead-qualification bots without an engineer

• Operating company. HELLO UMI, S.L.
• Jurisdiction. EU (Spain)
• Where the data sits. EU (Spain)
• Independent checks. GDPR, SOC 2
• Source code. Closed source
• Replaces. Drift, ManyChat, Chatfuel

Landbot is the chatbot-first tool in this category, and that is why it leads it. The whole product is a visual, no-code flow builder for structured conversations between a bot and a visitor, not a live-chat widget with a bot added later.

A marketing team designs the conversation the way it would lay out a landing page, with conditional branching and A/B testing of different paths, and a human handoff point for when the bot should step aside. The practical effect is that the people who own the funnel can also own the conversation, and revise it as results come in.

The same flow deploys to a website widget, WhatsApp and Messenger, and native integrations push qualified leads into HubSpot, Salesforce or Pipedrive. AI agents can also be grounded in a company knowledge base instead of running on scripted flows alone.

Pricing is published across five tiers, from a free plan with 100 chats a month to Business from EUR 400, with extra chats at EUR 0.05 each and a 14-day trial on paid plans. Both the chat quotas and the AI chat quotas are stated per tier, so the arithmetic for a given traffic level can be done before anyone talks to a salesperson.

HELLO UMI, S.L. in Barcelona has run Landbot since 2015, and the company states GDPR compliance and SOC 2 certification.

The trade-offs are structural: there is no ticketing or call-centre module, so it is not a helpdesk replacement, WhatsApp needs the EUR 160 Professional WhatsApp tier, and per-chat overage makes cost less predictable than a flat per-seat plan at scale. Even so, for a team whose goal is conversion rather than ticket resolution those are manageable limits, and the published tiers make it cheap to test before committing to anything above the Starter plan.

Standout feature. The visual flow builder with branching and A/B testing, deployed to web, WhatsApp and Messenger from a single design.

#2 Tiledesk

Galatina (Lecce), Italy Pro EUR 149 per month (EUR 124 billed annually) / Business EUR 499 per month (EUR 416 billed annually) / Enterprise custom; self-hosting available No free commercial tier; free access for qualifying open source projects by application

Best for: Technical teams that want a chatbot builder they can self-host

• Operating company. Tiledesk S.r.l.
• Jurisdiction. EU (Italy)
• Where the data sits. Self-hosting or private cloud available
• Independent checks. GDPR
• Source code. Open source
• Replaces. Drift, Intercom, Chatfuel

Tiledesk is an open-source chatbot platform from Tiledesk S.r.l., an Italian company in Galatina, in the province of Lecce. Its distinguishing option is self-hosting or private-cloud deployment, which almost no hosted chatbot-builder offers, and which matters to a European buyer who wants conversations and lead data on infrastructure it controls.

The visual builder, called the Design Studio, lets a team assemble AI agents for sales, support or onboarding with explicit lead qualification and routing. For a developer-led team that is the more interesting half of the product, because the flow design and the hosting decision belong to the same buyer.

One flow deploys across web, WhatsApp, Messenger, SMS, email and voice. Pricing is published across three tiers: Pro at EUR 149 a month (EUR 124 billed annually) covers 3 users, 20 AI agents and 3,000 conversations, Business at EUR 499 a month scales to 5 users, 50 AI agents and 5,000 conversations, and Enterprise is custom-priced.

A white-label option exists for agencies, and qualifying open source projects can apply for free access. The AI agent allowances and token counts are listed per tier, which makes the plans comparable on paper, though the tiers are priced above the entry points of most hosted rivals in this list.

The trade-off is polish and effort. There is no permanent free commercial tier, self-hosting needs a team that can run and maintain the infrastructure, and entry pricing sits above Landbot or Crisp.

A team that wants a wizard-driven hosted tool will find Tiledesk a steeper setup; one that values control over its data will find it the most flexible option here. Teams without that capacity should treat the hosted plans as the normal route and the self-hosted option as a reason to keep Tiledesk on the shortlist, not as a default.

Standout feature. Self-hosting: a team with strict residency needs can run the bot and its conversation history entirely on its own servers.

#3 Crisp

Nantes, France Founded 2015 Free (2 operators) / Pro EUR 25 per month per workspace / Unlimited EUR 95 per month Free tier

Best for: Startups and SMBs that want a chatbot inside a full messaging inbox

• Operating company. Crisp
• Jurisdiction. EU (France)
• Where the data sits. EU
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Intercom, Zendesk Chat

Crisp is an all-in-one customer messaging platform from Nantes, France, and the chatbot is one layer of a wider product rather than the product itself. Live chat, a shared inbox across channels, a chatbot builder, a knowledge base, a built-in CRM and video calls sit in one workspace.

For a small team replacing Intercom, the appeal is that a visitor can start with a bot answer and move to a human in the same thread. A bot answer and a human reply live in the same conversation, which keeps the visitor from being sent to a second channel.

Pricing is per workspace instead of per seat, which changes who can answer a customer.

The free Basic plan covers two operators, Pro is EUR 25 a month with four operators, and Unlimited is EUR 95 with no cap on operators, so a developer or a finance colleague can answer one question without a licence.

Crisp states GDPR compliance and EU processing, and offers annual discounts and special pricing for startups and non-profits. The pricing model also suits companies where support is a part-time job spread across a whole team, rather than a dedicated department with its own seats to count.

As a chatbot platform it is lighter than the bot-first builders. Chatbot and knowledge base features sit on the Pro plan, there is no self-hosting, and reporting and enterprise controls are thinner than Userlike.

It is the right choice when the shared inbox is the job and the bot is there to absorb repetitive questions, and the wrong one when lead qualification flows are the main goal. Teams that mainly want to build branching lead-qualification journeys should look at Landbot or Tiledesk first, and treat Crisp as the inbox that happens to include a bot.

Standout feature. Unlimited operators for a flat workspace price, so adding a colleague to answer a customer costs nothing extra.

#4 Userlike

Cologne, Germany Founded 2011 Free tier / Team from about EUR 90 per month Free tier

Best for: German and regulated businesses that must document chat compliance

• Operating company. Userlike
• Jurisdiction. EU (Germany)
• Where the data sits. German data centres
• Independent checks. ISO 27001, GDPR
• Source code. Closed source
• Replaces. Intercom, Zendesk

Userlike, now sold under the Lime Connect brand, treats compliance as part of the product. Processing happens in German data centres, the company holds ISO 27001 certification, retention policies can be configured with automatic deletion, and the chat widget has cookie consent and explicit opt-in built in.

For a bank, insurer or healthcare provider putting a bot in front of customers, those controls are what the procurement team actually asks about. Few of the other tools here put that much of the compliance story in the product itself, rather than in a policy page the buyer has to take on trust.

It also adds the sector controls those buyers are audited on: IP-based access restrictions, audit logging, redaction of sensitive information inside conversations, and SAML single sign-on.

Redaction matters more than it sounds, because customers routinely paste card numbers or medical details into a chat window, and a transcript archive that keeps them becomes a liability. The product itself is an omnichannel messaging platform with a unified inbox, AI automation and chatbots from Cologne. For a regulated buyer these controls are usually the shortlist criteria, and they are listed in the product rather than negotiated in an enterprise contract after the fact.

The free tier is usable, with one widget and one operator seat, and paid plans start around EUR 90 a month for Team, with the Corporate and Flex plans unlocking full AI, WhatsApp campaigns and advanced analytics. That entry price is high for a small business and reasonable for a mid-market one.

There is no self-hosting, and the strongest fit is German-speaking and regulated markets rather than a growth team building bot funnels. It is a sensible choice when a compliance officer will read the vendor's documentation, and a heavier one when a small marketing team simply wants a bot on a landing page.

Standout feature. Redaction inside the transcript, so a card number pasted into the chat can be stripped before it becomes a permanent liability.

#5 Trengo

Utrecht, Netherlands Founded 2017 From EUR 19 per user per month Free trial

Best for: SMBs that want chatbots and every channel in one shared inbox

• Operating company. Trengo B.V.
• Jurisdiction. EU (Netherlands)
• Where the data sits. EU (Netherlands)
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Zendesk, Intercom, Front

Trengo is a Dutch customer engagement platform, founded in 2017 and based in Utrecht, built around a shared inbox that gathers email, live chat, WhatsApp, Messenger, Instagram, SMS and voice into one timeline. The chatbot sits on top of that inbox and handles repetitive questions before a person picks the thread up.

For a small or mid-sized business the value is consolidation: a support team stops switching between tabs and stops losing the message that arrived in a channel nobody had open. That single timeline is the main reason to pick it, since the bot, the agents and the customer all see the same history.

Team collaboration follows the same idea. Conversations are assigned to a named person, internal notes travel with the thread so context does not live in someone's head, and WhatsApp is treated as a first-class channel, which matters in European markets where it is the default way customers contact a business.

Trengo B.V. states GDPR compliance with EU processing, which does real work for a shared inbox full of order details, addresses and complaints. The bot therefore takes the first pass on the repetitive questions, and the agent who picks up the thread sees what the customer has already been told.

Pricing starts at EUR 19 per user per month, with a free trial.

Trengo is aimed at SMBs rather than enterprise contact centres, so advanced routing, workforce management and deep analytics sit below what a large operation expects, and the chatbot is closer to a deflection layer than a lead-qualification builder like Landbot or Tiledesk. Teams that need a visual lead-qualification builder, or that expect to scale into a large contact centre, will outgrow it, while a shop or agency with a handful of agents will find it covers the daily work.

Standout feature. WhatsApp as a first-class channel inside the shared inbox, which is how a large part of Europe actually contacts a business.

#6 Smartsupp

Brno, Czech Republic Free / Solo $17, Plus $25, Expert $83 per month billed annually ($24, $35, $117 monthly); Ultimate from $280 per month Free tier + 14-day trial

Best for: Online shops that want a bot trained on their product catalogue

• Operating company. Smartsupp.com, s.r.o.
• Jurisdiction. EU (Czech Republic)
• Where the data sits. Germany, on Amazon Web Services (AI features use OpenAI Ireland, where data may leave the EU)
• Source code. Closed source
• Replaces. Intercom, tawk.to, Zendesk Chat

Smartsupp is live chat for online shops from Smartsupp.com, s.r.o. in Brno, Czech Republic, and its chatbot angle is a catalogue-aware AI agent called Mira that can be trained on up to 30,000 products.

A visitor asking about a product gets an answer drawn from the shop's own data rather than a scripted menu. Chatbot and automation workflows sit alongside the live chat widget, and the product is aimed at shops replacing Intercom, tawk.to or Zendesk Chat rather than at ticket-heavy service desks. That catalogue grounding is what separates it from a generic FAQ bot in a shop setting, where most questions concern products rather than policies.

There is a free tier and a 14-day trial. Paid plans billed annually cost $17 a month for Solo, $25 for Plus and $83 for Expert, or $24, $35 and $117 on monthly billing, and Ultimate starts at $280 a month.

Solo is among the lowest paid entry prices in this category, while the step from Expert to Ultimate is the one a growing shop should price before it needs it. Annual billing saves roughly 30 percent on the lower tiers, and the free tier lets a small shop try the widget before paying anything at all.

The data path deserves a careful read. Smartsupp stores data in Germany on Amazon Web Services, so the company is Czech, the servers are German and the infrastructure provider is American. Its AI features use OpenAI Ireland, where data may leave the EU.

A shop that needs every conversation kept inside the EU should leave those features off or obtain the transfer terms in writing first. None of this makes Smartsupp unsuitable, but it is a different promise from a vendor that hosts and processes everything inside the EU, and the buyer should know which one they are accepting.

Standout feature. A catalogue-trained AI agent that puts a shop's own product data behind the answers in the chat window.

#7 LiveAgent

Slovakia Small Business $15 / Medium Business $29 / Large Business $49 / Enterprise $69 per agent per month, billed annually 30-day free trial, no card required; no permanent free tier

Best for: Support teams that want proactive chat invitations inside a helpdesk

• Operating company. Quality Unit, s. r. o.
• Jurisdiction. EU (Slovakia)
• Independent checks. GDPR (data processing agreement available)
• Source code. Closed source
• Replaces. Drift, Intercom, Zendesk

LiveAgent is built and operated by Quality Unit, s. r. o., a Slovak software company, which keeps both the product and the contract under EU jurisdiction.

It is first a helpdesk, with ticketing, live chat and a call centre in one product, and its conversational-marketing layer sits on top rather than being the whole product. Proactive chat invitations trigger automatically from visitor behaviour, and a 24/7 AI support agent answers routine questions and hands off to a human when it runs out of confidence. A team replacing a chat widget plus a ticketing tool can consolidate both under one contract with one Slovak company.

Real-time visitor monitoring lets an agent see who is browsing and trigger an invitation on the right page, and feedback buttons and satisfaction surveys close the loop after the conversation.

Pricing is published in four per-agent tiers, $15, $29, $49 and $69 a month billed annually, every tier includes an AI Answer Assistant, and there is a 30-day free trial with no card required but no permanent free plan. The satisfaction surveys and feedback buttons sit alongside the tickets in the same product, so the invitation and the support outcome can be reviewed in a single place.

It is not a dedicated lead-qualification bot builder the way Landbot or Tiledesk are. The flows are simpler, there is no visual designer for qualification sequences, and per-agent pricing climbs for a larger team compared with conversation-based pricing.

A team that wants a marketing bot first should weigh that against the broader helpdesk feature set, which is the real reason to choose it. For teams already running a support desk, the proactive layer is a pleasant addition, and for teams buying a bot to generate leads, it is a thinner offer than the specialist tools.

Standout feature. Behaviour-triggered chat invitations in every tier, the nearest thing to a marketing-bot trigger a helpdesk ships.

#8 Kindly

Oslo, Norway Founded 2016 Session-based pricing on an annual commitment, quoted per organisation Free trial; no permanent free tier stated

Best for: High-volume retailers that need one bot across 100+ languages

• Operating company. Kindly AS
• Jurisdiction. EEA (Norway)
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Drift, Intercom, Tidio

Kindly is operated by Kindly AS in Oslo, Norway, founded in 2016, and is a Norwegian AI chatbot built around a visual, no-code dialogue builder and support for more than 100 languages out of the box.

That language count is the widest stated in this category, and it matters to a European retailer or marketplace selling across many language markets from one bot rather than one bot per market. The product is aimed at companies with high conversation volume, where one bot answering consistently in many languages can replace a separate bot for each market.

The agent deploys across chat, voice, in-app and messaging channels including WhatsApp, and it personalises in real time using connected CRM, helpdesk and order-management data, so a returning customer can be asked about the order they actually placed.

It is positioned at high-volume conversational commerce rather than a handful of daily conversations, and the company runs a public trust centre for security and compliance questions. The practical result is one bot that can answer in the customer's own language and draw on order and helpdesk data, rather than a generic FAQ that deflects to email.

Pricing is the obstacle. It is session-based on an annual commitment and not published anywhere on the vendor site, so every plan is quoted per organisation after a sales conversation, which makes budgeting harder than a monthly published tier.

Norway is in the EEA rather than the EU, which for GDPR purposes is the same regime. Small businesses will find the product and the sales motion pitched above them. Anyone shortlisting it should ask early for a price range and for a pilot scope, since the commercial discussion decides whether it fits at all.

Standout feature. The widest language coverage stated in this category, 100+ languages from a single dialogue builder.

#9 giosg

Helsinki, Finland Founded 2011 Quoted per organisation after a discovery call, starting from EUR 790 per month No free tier or trial stated; demo on request

Best for: Enterprises replacing several engagement tools with one EU-hosted platform

• Operating company. giosg.com Oy
• Jurisdiction. EU (Finland)
• Where the data sits. All customer data stored in the European Union
• Independent checks. ISO 27001, GDPR
• Source code. Closed source
• Replaces. Drift, Intercom, Zendesk Chat

giosg is run by giosg.com Oy, a Finnish limited company registered in Helsinki in January 2011 under business ID 2388009-8.

Its platform is a bundle of engagement tools: AI agents for support, shopping and lead capture, live chat, an interaction builder for pop-ups and quizzes, video bots, and WhatsApp and telephony channels, with support for more than 70 languages. The pitch is replacing several point tools with one platform for support, sales and marketing teams. It is aimed at companies that run chat, forms and campaigns across several teams and want one vendor to answer for all of them.

Delivery is project-shaped. The vendor describes a discovery call, a demo and a pre-study before building, and says it prices for value rather than seats, with a starting point of EUR 790 a month stated on the pricing page and everything above that quoted.

There is no free tier or self-serve trial, so evaluation means a sales process, which suits enterprise buyers and rules out a quick experiment. That model suits organisations with a procurement process and an integration team, and it works against a marketing manager who simply wants to try a bot this afternoon.

On compliance, the vendor states ISO 27001 certification, GDPR compliance, EU data residency with all customer data stored in the EU, and a VAULT feature that controls where its services can be used from.

A company registered since 2011 makes it one of the longer-lived entries here. Published customer cases skew to telecom, automotive, housing and banking. The Finnish trade register lists the company since 2011, and the vendor discloses where data lives, which is more than several quote-only competitors here do.

Standout feature. One Finnish platform covering AI agents, live chat, video bots and lead capture, with ISO 27001 and EU-only data storage.

#10 Leadoo

Helsinki, Finland Founded 2018 Quoted per domain in three packages (Engage, Expand, Elit); Leadoo Lite is free Leadoo Lite (free analytics tier)

Best for: Website-focused B2B teams measuring conversion lift from chat and lead tools

• Operating company. Leadoo Marketing Technologies Oy
• Jurisdiction. EU (Finland)
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Drift, Qualified, HubSpot chatbot

Leadoo is run by Leadoo Marketing Technologies Oy in Helsinki, business ID 2922046-1, with a UK subsidiary, Leadoo Marketing Technologies Ltd.

Having rebranded as Leadoo AI, it describes a conversion and customer-experience platform: AI conversational tools that engage visitors and qualify leads, live chat, a personaliser, calendar booking, and analytics that identify companies visiting the site. It is built for a marketing team that wants to see which pages convert, not only to answer questions. It shares the Finnish home market with giosg, but its centre of gravity is the website conversion funnel rather than the support queue.

Pricing is quoted per domain in three packages, Engage, Expand and Elit. Engage covers 3 live chat agents and 250 AI chats a month, Expand covers 10 agents and 2,500 chats, and the top tier 10,000 chats, with conversion expert consulting hours included per year.

Leadoo Lite is a free tier that samples the analytics, with company identification, website analytics and a sales assistant, but not the full chatbot. The packages scale by domain, chat volume, live chat seats and consulting hours, which makes it clear what grows as a company moves up a tier, even without a price attached.

No list price is published, and the packages are described by feature rather than by cost, so budget needs a quote. Its security and GDPR pages state GDPR compliance and a cookieless approach to analytics, and the terms reference the EU AI Act and Data Act.

Leadoo suits B2B sites with enough traffic for conversion testing; a shop wanting a catalogue bot or a support deflection tool will find other entries closer. That narrower focus is a strength for the right buyer, but it means Leadoo is not a replacement for a helpdesk or a WhatsApp support operation.

Standout feature. Company identification and conversion analytics sit under the same login as the chatbot, with a free Lite tier to try the analytics.

#11 Hubtype

Barcelona, Spain Not published; demo-led, quoted per use case None stated; demo on request

Best for: Large contact centres running WhatsApp as the main customer channel

• Operating company. Metis Solutions, S.L.
• Jurisdiction. EU (Spain)
• Independent checks. ISO 27001, GDPR
• Source code. Open source
• Replaces. Intercom, Zendesk, Drift

Hubtype is operated by Metis Solutions, S.L., based in Barcelona, and describes itself as an agentic customer-experience platform for designing, deploying and managing AI agents on WhatsApp and other messaging channels.

It positions as a Meta Business Partner and says it has been improving customer experience for brands for more than ten years, and lists airlines, insurance and banking among its industries. The product combines a flow builder, a helpdesk and an analytics suite. Its pitch is that WhatsApp is no longer just a channel for notifications, but a place where a customer can complete a task with a bot or a person.

It is built for high conversation volume, where scalability and security determine what can be automated. The company states ISO 27001 certification, end-to-end encryption on conversations, secure SSL webhooks, and alignment with the Spanish National Security Scheme (ENS) in its security policy.

Its Botonic bot framework is published on GitHub under the MIT licence, which gives developers an open code path even though the platform itself is proprietary. For a regulated buyer the combination of an ISO 27001 certificate, a public security policy and an open framework is easier to audit than a closed bot with a brochure.

No prices are published and no pricing page was found on its site, so the route in is a demo and a quote scoped to the use case. That is normal for enterprise messaging projects and inconvenient for a small team comparing options.

Hubtype fits a company with a contact centre, WhatsApp as its main channel and an integration team, and is far more than a small shop needs. It is a sound choice for a bank, insurer or airline with a contact centre, and an unnecessary one for a small shop that wants a website chat widget.

Standout feature. A WhatsApp-first agent platform with an MIT-licensed bot framework underneath, from a Barcelona company certified to ISO 27001.

#12 Chatarmin

Vienna, Austria Custom plan per shop volume, no list prices; Meta conversation fees passed through with EUR 0.00 markup Free trial offered on the site ("kostenlos testen")

Best for: Online shops that want WhatsApp marketing and an AI chatbot together

• Operating company. chatarmin.com GmbH
• Jurisdiction. EU (Austria)
• Independent checks. GDPR (data processing agreement published)
• Source code. Closed source
• Replaces. Drift, Klaviyo SMS, Gorgias

Chatarmin is made by chatarmin.com GmbH in Vienna, entered in the Austrian commercial register under number 555067a at the Commercial Court of Vienna.

It is a customer-experience tool for e-commerce that joins WhatsApp marketing and AI customer service: newsletters, automated flows such as abandoned cart and post-purchase journeys, a shared WhatsApp inbox, an AI chatbot and AI agents, an AI voice assistant, and a ticketing system.

The company names its two managing directors in its imprint. Its argument is that the customer who gets a WhatsApp campaign and the customer who asks a question about it are the same person, and should meet the same system.

It connects to Shopify, WooCommerce, Shopware, Magento, Klaviyo, Emarsys, Zendesk and Gorgias, so order data can drive both campaigns and support answers. The chatbot handles automated replies and product guidance with automatic escalation to agents, and the shop trains it on its own data.

Chatarmin positions itself as a replacement for stitching together a newsletter tool and a support desk for WhatsApp. Because campaigns and support share one inbox, a reply to a promotional message lands with the team that can answer it, rather than in a separate marketing tool.

Pricing is a custom plan based on shop volume, with no list price, and Meta's conversation fees are passed through with a stated EUR 0.00 markup. That makes the real cost depend on message volume, so a small shop should get a quote before committing.

It is narrower than a general chatbot platform: it fits WhatsApp-led commerce, and a team that needs website lead qualification or a multi-channel helpdesk will look to the others. Shops that sell mainly through Shopify or WooCommerce will find the integrations a good fit, while B2B firms and multi-channel service desks will find the focus too narrow.

Standout feature. Marketing flows and AI support on the same WhatsApp inbox, wired into the shop catalogue and order data.

#13 moin.ai

Hamburg, Germany Founded 2015 Business EUR 750 per month billed annually (EUR 880 monthly) / Growth EUR 1,350 per month billed annually (EUR 1,580 monthly) / Professional EUR 2,500 per month billed annually (EUR 2,930 monthly) None; minimum contract of 3 months on the entry tier

Best for: German enterprises that want an AI chatbot across marketing, sales and service

• Operating company. knowhere GmbH
• Jurisdiction. EU (Germany)
• Where the data sits. German server hosting
• Independent checks. GDPR
• Source code. Closed source
• Replaces. Drift, Intercom, HubSpot chatbot

moin.ai is operated by knowhere GmbH, registered in Hamburg under commercial register number HRB 135686.

The vendor states it was founded in March 2015 to build a travel app, pivoted to chatbots in 2016 and rebranded to moinAI in 2020 when it moved to a SaaS model, which gives it one of the more clearly documented histories here.

The product spans marketing, sales and service: an AI chatbot, live chat with human handover, a RAG-based knowledge base, generative content creation and product recommendations. It has sold chatbots as SaaS under the moin.ai name since 2020, longer than many newer entrants here.

Pricing is published across three tiers with minimum terms: Business at EUR 750 a month billed annually (EUR 880 month to month) with a 3-month minimum, Growth at EUR 1,350 with 6 months, and Professional at EUR 2,500 with 12 months.

Every tier includes unlimited conversations and German server hosting, which is unusual generosity on volume in a category where most vendors cap conversations even on paid plans. Because the conversation allowance is not metered, the cost of a busy month is predictable, and the number of AI agents, sites and live chat seats is what moves a customer between tiers.

It is the most expensive entry point in the category by a wide margin, more than seven times LiveAgent's entry tier, and there is no free tier or low-commitment way to trial it before a multi-month contract.

The vendor states more than 170 customers across finance, tourism, e-commerce, energy and manufacturing, so it is aimed at mid-sized and large companies, not at a small shop. For a mid-sized German or Austrian company with a service department and a marketing team that both want a bot, the price is defensible, while a small shop will find better value elsewhere.

Standout feature. Unlimited conversations at every tier, from a German company that publishes both its prices and its history.

#14 Watermelon

Utrecht, Netherlands Free (50 conversations/month) / Starter EUR 99 / Advanced EUR 199 / Business EUR 399 per month / Enterprise custom Free plan

Best for: Small teams that want an AI agent with lead generation and ISO 27001

• Operating company. Watermelon B.V.
• Jurisdiction. EU (Netherlands)
• Where the data sits. Servers hosted in Europe
• Independent checks. ISO 27001, GDPR
• Source code. Closed source
• Replaces. Intercom, Drift, Zendesk Chat

Watermelon is operated by Watermelon B.V., a Dutch company registered in Utrecht under Chamber of Commerce number 66844177.

The vendor states that it hosts servers in Europe and holds ISO 27001 certification alongside GDPR compliance with end-to-end encryption, a stronger compliance statement than most of this category publishes. The product runs one AI agent across customer service, lead generation, and HR and internal communication. For a small European business that wants a certificate to point to in a procurement questionnaire, that is a useful starting point.

Pricing is published across five tiers by conversation volume: a free plan with 50 conversations a month, Starter at EUR 99, Advanced at EUR 199 for 500 conversations, Business at EUR 399 for 1,000, and a quoted Enterprise tier.

The conversational-marketing features, automatic lead generation and visitor tracking, only unlock from Advanced at EUR 199 a month, so the free and Starter plans are closer to a support widget with an AI layer. Volume limits are counted in conversations rather than seats, so a small team can run a bot on a modest plan without paying for unused agent licences.

That gating is the main caveat, along with conversation-based pricing that scales steeply: EUR 399 a month buys 1,000 conversations before Enterprise volume is reached. The vendor does not state a founding year, which makes maturity harder to gauge against Landbot or moin.ai.

For a small team that wants a free start and published tiers from a certified Dutch company, it is a credible entry. The free plan is worth testing for the AI agent and the widget, but a team that bought the product for lead capture should budget for Advanced from day one.

Standout feature. ISO 27001 combined with a named automatic lead-generation feature, a rare pairing of formal compliance and marketing intent here.
