Every European low-code/no-code platform reviewed
Rotterdam, Netherlands
Founded 2005
Free tier; Standard from €918/month (one app) or €2,295/month (unlimited apps); Premium quoted
Free tier for prototypes and small personal apps; no SLA or support included
Best for: Version control built directly into the modeling environment — every change to an application is tracked the way a developer would track code, which is unusual among low-code tools and matters once more than one person is building the same app.
Mendix is a Rotterdam-founded, model-driven low-code platform for building enterprise applications, acquired by Siemens in 2018 and now sold as part of Siemens’ Digital Industries Software portfolio under the Siemens Intelligence Center X banner.
That ownership is worth stating plainly: Siemens AG is itself headquartered in Munich, Germany, so the acquisition keeps Mendix inside the EU rather than moving it offshore, while giving the platform a much larger balance sheet and — for manufacturers already running Siemens’ industrial software — a more direct line into OT and PLM systems than a standalone low-code vendor could offer.
The platform’s defining technical choice is baking version control into the modeling environment itself, so multiple developers working on the same application get the kind of change history and merge conflict handling that most low-code tools only approximate.
Pricing starts with a genuinely free tier for prototypes, then splits into a One App plan from €918/month and an Unlimited Apps plan from €2,295/month — Mendix is explicit that there's no technical difference between the two, only how many applications the licence covers. The Premium tier, which adds multi-region failover, a private marketplace and 24/7 support, is quote-only.
The trade-off is scale and complexity: this is built for organisations replacing core systems with a governed development process, not a small team shipping its first internal app, and the per-application pricing model means a company running many small tools will find the maths works against it. For an enterprise that wants an EU-domiciled low-code platform with real version control and Siemens-grade backing, it remains one of the most credible options in this category.
Pros
- Rotterdam-founded, still the platform’s operational home, with genuine enterprise scale behind it since Siemens’ 2018 acquisition
- Version control and collaborative development built into the platform itself, not bolted on
- Published entry pricing for the Standard tier — unusual for an enterprise-grade low-code platform
- Part of Siemens’ Digital Industries Software estate, which matters for manufacturers already running Siemens OT/industrial software
Cons
- Premium tier, the one enterprises actually need for HA and multi-region failover, is quote-only
- Pricing is metered by application count rather than a flat seat price, which punishes a company running many small apps
- Being owned by Siemens since 2018 means the roadmap now answers to a much larger parent company's priorities, not just Mendix's own
- Free tier explicitly excludes any support plan or uptime guarantee
Amsterdam, Netherlands
Founded 2007
Create €1,500/month; Scale €3,500/month; Enterprise quoted
No permanent free tier stated
Best for: Applications compile to standard, exportable React and WebAssembly rather than a proprietary runtime you can only run on Betty Blocks’ own servers — the platform is explicitly positioned against what it calls the ‘sovereignty gap’ most no-code tools leave a customer exposed to.
Betty Blocks was founded in Amsterdam in 2007 and built its early reputation on governed citizen development: letting non-developers build applications while IT retains oversight, a model that found particular traction with Dutch insurers and public-sector bodies.
The company has more recently repositioned around AI-driven application generation, emphasising that applications built on the platform compile to standard React and WebAssembly rather than a proprietary format only Betty Blocks can run — its own language for this is closing the ‘sovereignty gap’ that leaves customers of most no-code platforms unable to leave without rebuilding everything.
Pricing is published rather than quote-only at the entry tiers: Create is €1,500 a month and Scale is €3,500 a month, with Enterprise reserved for a custom quote. That is meaningfully more expensive than the other Dutch options in this category (Mendix's free tier, Ninox's per-user pricing), which positions Betty Blocks as a mid-market-and-up purchase rather than a small team's first low-code tool.
Where it earns its place in this category is the export story: a customer who wants to leave, or who wants to self-host, can point to standard React and WebAssembly output rather than a black box, which is a genuinely different answer to lock-in than most no-code vendors give. It suits an organisation that has been burned by vendor lock-in before, or one in a regulated Dutch sector that already expects a formal citizen-development governance model.
Pros
- Founded in Amsterdam in 2007, with a straightforward, published two-tier pricing structure before the inevitable enterprise quote
- Application code exports in standard formats (React, WebAssembly), a genuine answer to the usual no-code lock-in complaint
- Originally built around governed citizen development, which shows in how deliberately IT oversight is designed into the workflow
- Deployment infrastructure choice is left to the customer rather than forced onto Betty Blocks’ own cloud
Cons
- Published entry pricing starts at €1,500/month — high for a small team compared with Mendix's free tier or Ninox's per-user pricing
- The platform's own marketing has shifted meaningfully toward ‘AI application generation’, which makes it harder to evaluate against its longer no-code track record
- No independently confirmed compliance certification (SOC 2/ISO 27001) found on the pages checked for this review
- Best documented for citizen-developer governance in regulated Dutch sectors (insurance, public sector); less proven outside that use case
Berlin, Germany
Founded 2014 (rebranded 2021)
Free (up to 5 users); Team €25/user/month annual; Business €40/user/month annual; Enterprise quoted
Genuine free tier for up to 5 users, 100MB storage, 5,000 records
Best for: A proprietary scripting language sits underneath the visual builder, so a Ninox application can express real business logic — calculated fields, triggers, custom functions — that a pure no-code database can't, while staying far lighter than an enterprise platform like Mendix.
Ninox is built by Ninox Software GmbH, headquartered in Berlin, founded in 2014 and rebranded in 2021 after running Germany's fastest crowdfunding campaign the year before. It sits between a no-code database and a full application platform: relational tables and forms come first, but a proprietary scripting language underneath lets a non-developer add calculated fields, triggers and small pieces of real logic that a plain database tool can't express.
Pricing is published in full: a genuine free tier for up to 5 users and 5,000 records, then Team at €25 a user a month and Business at €40 a user a month, both billed annually, with Enterprise reserved for organisations that want a private-cloud deployment. That transparency, combined with German hosting, is a large part of why the vendor reports over 5,000 customers concentrated in the German and Swiss Mittelstand.
The honest limitation is maintainability: Ninox's scripting language is proprietary and thinly documented outside German, so an application built by one person becomes hard for a successor to read, and performance is known to degrade once tables grow large. It is the right tool for a small back-office team building its own departmental database with some logic attached — not for an application meant to scale past a few hundred thousand records or outlive its original builder.
Pros
- Berlin-headquartered (Ninox Software GmbH), with a genuine free tier for up to 5 users, not just a trial
- Published, transparent per-user pricing on every paid tier, including Enterprise’s private-cloud option
- A built-in scripting language lets a non-developer add real logic — formulas, triggers, automations — beyond a plain database
- Widely adopted among German and Swiss Mittelstand back offices, per the vendor's own customer figures (5,000+ customers stated)
Cons
- The scripting language is proprietary to Ninox and sparsely documented in English, so applications are hard for anyone but their original author to maintain
- Performance is reported to degrade on very large tables — this is a tool for departmental applications, not enterprise-scale data volumes
- No third-party compliance certification (SOC 2, ISO 27001) stated on the pages checked
- Free tier is capped tightly (100MB, 5,000 records), useful for evaluation rather than production use
Apeldoorn, Netherlands
Founded Not stated by the vendor
Not published; quote only
No free tier stated
Best for: A dedicated ‘Upcycler’ component is built specifically to analyse and transform legacy application code as part of a migration, rather than leaving the migration itself entirely as professional-services work the way most low-code vendors do.
Thinkwise is a Dutch low-code vendor headquartered in Apeldoorn, built around a model-driven approach to a specific, hard problem: replacing a legacy ERP, WMS, TMS, PIM, MES or OMS system that a business has outgrown but can't easily walk away from. Rather than generating one application from a set of screens, Thinkwise generates the whole application — data model, business logic and interface — from a shared model that can be adapted as the business changes.
The platform's distinguishing feature is a component the vendor calls the Upcycler, built specifically to analyse and transform logic out of a legacy system as part of a migration, which is normally the single most expensive and riskiest part of any modernisation project and something most low-code vendors leave entirely to professional services.
AI-assisted modelling has been layered onto the platform more recently, on top of what was already a mature model-driven core rather than as a young product's headline feature.
Pricing is not published anywhere on the vendor's site — every engagement starts as a sales conversation — and no founding date or customer count is disclosed, which limits independent verification of the company's scale.
This is not a tool for a team that wants to ship a small departmental app this week; it is aimed specifically at large organisations undertaking a multi-year replacement of a business-critical legacy system, where the model-driven approach and the Upcycler's migration tooling are worth the steeper learning curve.
Pros
- Genuinely EU-headquartered (Apeldoorn, Netherlands), with a model-driven approach that separates business logic from the generated interface
- Purpose-built for legacy modernisation — ERP, WMS, TMS, PIM, MES, OMS — rather than a generic ‘build anything’ pitch
- The Upcycler component gives it a concrete answer to the hardest part of any legacy replacement: what happens to the old system's logic
- AI-assisted modelling layered onto an already mature model-driven core, rather than an AI feature bolted onto a young product
Cons
- No published pricing anywhere — every deal starts with a sales conversation and a quote
- No founding date, team size or customer count disclosed on the vendor pages checked, which makes independent scale verification difficult
- The model-driven approach has a steeper learning curve than a form-and-workflow builder like Betty Blocks or Ninox
- Positioned squarely at large, complex, multi-year modernisation projects — not a fit for a team that wants to ship a small app this week
Würzburg, Germany
Founded 2012
Not published; quote only (a ‘Discovery Call’ is required)
No free tier stated
Best for: Deep, certified SAP integration — Simplifier is an SAP Silver Partner and a SAP-Certified Business Technology Platform provider — aimed specifically at companies that want to build apps against SAP without committing entirely to SAP's own BTP low-code tooling.
Simplifier is a German low-code platform built by Simplifier AG, headquartered in Würzburg since 2012, with a stated 740 employees and more than 300 customer projects delivered. Its specific niche inside this category is SAP integration: Simplifier is an SAP Silver Partner and a SAP-Certified Business Technology Platform provider, which means it is explicitly positioned as an alternative — or a complement — to building low-code apps directly on SAP's own BTP tooling.
Beyond SAP, the platform is also a Microsoft Partner and lists on both AWS and Azure Marketplace, so a customer isn't locked into an SAP-only deployment story even if that's the platform's main selling point. Pricing is not published anywhere on the site; every engagement begins with a ‘Discovery Call’, which is typical for this SAP-adjacent tier of enterprise software but does mean no number appears before a sales conversation.
The vendor's own marketing claims a 40% total-cost-of-savings figure against SAP BTP, which is a vendor-stated number rather than an independently verified one and should be read that way. Simplifier makes the most sense for a company already running a significant SAP estate that wants a dedicated low-code layer over it; a company without SAP in its stack gets comparatively little advantage from choosing it over Mendix, Betty Blocks or Ninox.
Pros
- Würzburg-headquartered (Simplifier AG), operating since 2012 with a stated 740 employees and 300+ customer projects
- Certified SAP Silver Partner and SAP-Certified Business Technology Platform provider — a genuine SAP-integration specialism
- Also a Microsoft Partner with AWS and Azure Marketplace listings, so it isn't purely SAP-locked as a deployment option
- Vendor states over 100,000 end users across its customer base, suggesting real production scale
Cons
- No published pricing anywhere — every quote requires a discovery call with sales
- The vendor's own ‘40% TCO savings vs SAP BTP’ claim is unverified marketing and should be treated as such, not as an independent finding
- No independent security certification (SOC 2, ISO 27001) found on the pages checked, despite the SAP partner credentials
- Its core value proposition is specifically SAP integration — a company without an SAP estate gets little advantage over the other EU alternatives in this category
Oslo, Norway
Founded Not stated by the vendor
Not published; quote only
No free tier stated
Best for: The platform is built specifically to close what the vendor calls the ‘execution gap’ between what SAP manages and how work actually happens — building applications, multi-step processes and now AI agents directly against SAP and connected systems, rather than being a generic app builder that happens to have an SAP connector.
Neptune Software is a Norwegian low-code vendor headquartered in Oslo, built specifically around SAP-native application development. Rather than positioning itself as a general-purpose app builder, the platform — sold as Neptune DXP — is designed to close what the vendor calls the ‘execution gap’ between what SAP manages centrally and how work actually happens day to day, by letting customers build applications and orchestrate multi-step processes directly across SAP and connected systems.
Scale claims from the vendor are substantial: over 600 customers across 43 countries and more than 5 million licensed users, figures that — if accurate — would put Neptune among the larger SAP-adjacent low-code vendors, though these are vendor-stated numbers rather than independently audited ones. The product has also recently added the ability to deploy AI agents directly into applications and processes, extending its SAP-native approach into agentic workflows.
Pricing is entirely quote-only, and the vendor discloses no founding date on the pages checked, which limits how much of its history can be independently verified. As with Simplifier, the platform's value is concentrated almost entirely in companies that already run SAP: for that audience it offers a genuinely SAP-native alternative to building directly on SAP BTP or Fiori; for anyone without an SAP estate, the other EU vendors in this category are a better starting point.
Pros
- Genuinely EEA-headquartered (Oslo, Norway), with a large stated licensed-user base — over 5 million users across 600+ customers in 43 countries
- SAP-native positioning throughout the product, not a generic low-code tool with an SAP plugin added later
- Process orchestration across SAP and connected systems, not just single-screen app building
- Recent addition of deployable AI agents directly into applications and processes, built on an already SAP-mature core
Cons
- No published pricing anywhere on the site; every deal is quote-only
- No founding date disclosed, which limits independent verification of the company's history and scale claims
- Like Simplifier, its core value proposition assumes an existing SAP estate — limited advantage for a company outside SAP
- No third-party security certification (SOC 2, ISO 27001) stated on the pages checked
Kraków, Poland
Founded Not stated by the vendor
Not published; quote only
No free tier stated
Best for: InstantChange™, the vendor's name for modifying a live business process without redeploying or interrupting instances already in flight — a specific answer to the usual low-code complaint that changing a workflow mid-flight is disruptive or impossible.
WEBCON is a Polish low-code vendor headquartered in Kraków, selling what it calls the WEBCON BPS (Business Process Suite) Platform.
It sits at the process-automation end of this category — closer in spirit to Appian than to a general-purpose builder like Mendix or Betty Blocks — and is explicit about that positioning: the vendor describes it first as a platform to ‘automate and manage business processes across the entire organisation’, with application-building as the mechanism for doing that rather than the headline pitch.
The platform's named technology, InstantChange, lets a live business process be modified without redeploying the system or breaking process instances already in flight — a real answer to a problem most workflow tools handle badly, where changing a form or a routing rule mid-process either breaks existing cases or requires a maintenance window.
WEBCON states substantial enterprise scale: over 1,000 enterprise clients and 400,000 active end users across more than 70 countries, with deep integration into existing ERP systems and the Microsoft ecosystem.
Because of its BPM-first framing, WEBCON is a better fit for financial approvals, HR workflows, manufacturing operations and document-heavy processes than for building a standalone customer-facing product — evaluate it as a process platform that happens to build applications, not an application platform that happens to route processes. No pricing is published and no founding date is disclosed, so budgeting and company history both require a direct conversation with the vendor.
Pros
- Kraków-headquartered, with substantial stated enterprise scale: 1,000+ enterprise clients and 400,000+ active end users across 70+ countries
- InstantChange technology addresses a genuine operational pain point: modifying a live process without breaking in-flight instances
- Deep integration with existing ERP systems and the Microsoft ecosystem, useful for organisations already standardised on Microsoft tooling
- Applications span financial processes, HR workflows, manufacturing operations and document management, evidence of genuine breadth beyond a single use case
Cons
- WEBCON describes itself first as a ‘business process automation platform’ — it sits closer to the BPM/workflow-automation end of this category than a general-purpose app builder like Mendix or Betty Blocks
- No published pricing anywhere on the vendor's site
- No founding date, employee count or compliance certification disclosed on the pages checked for this review
- Best suited to process-centric applications (approvals, document flows); less suited to building a standalone customer-facing product
