European Alternatives to Confluent
Looking for a European alternative to Confluent? Confluent, Inc. is a Delaware corporation according to its terms of use, and its pricing page states that all prices are in United States Dollars unless specifically stated otherwise. Confluent Cloud is usage-based, with Standard from about $385 per month and Enterprise from about $895 per month (starting costs assume about 70% utilization), and the pricing page header describes Confluent as an IBM company (checked on 3 November 2026).
The European tools below offer managed Apache Kafka, governance, stream processing and, in four cases, message brokers, from vendors in Finland, the Netherlands, the United Kingdom, Germany, Poland and Sweden.
How we rank these tools — 4-step process
-
1
European ownership, verified
The company is headquartered and incorporated in the EU, EEA, the UK, Switzerland or Israel, and processes customer data in Europe or Israel. A US parent company disqualifies a tool from this page regardless of where its servers are.
-
2
Category fit and hands-on review
What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.
-
3
Compliance and pricing check
GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

Position on this page
Placement on this page can be paid, and that can affect which tools appear here and the order they appear in. It never buys a good review: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.
Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Vendors can pay for more visibility, higher up on the review pages; it never affects which tools are listed. Editorial policy

Why people leave Confluent
Confluent is a US company that sells Apache Kafka as a product. According to its terms of use, the contracting party is Confluent, Inc., a Delaware corporation, and the header of its pricing page describes it as an IBM company. A European buyer who opens a Confluent contract is therefore signing with a US entity inside a larger US group.
Confluent Cloud is billed on usage, and the numbers on the pricing page are in United States dollars unless stated otherwise. The Standard tier starts at about $385 per month and the Enterprise tier at about $895 per month, and Confluent notes that these starting costs assume roughly 70% utilization. A budget in euros therefore carries an exchange rate that you do not control, and a bill that moves with traffic.
Most people who look beyond Confluent are not unhappy with Kafka itself. They want one of three things: a contract with a European company, a price that is easier to forecast, or a smaller piece of the stack. Some only need managed brokers, some only stream processing, and some do not need a Kafka log at all. This page sorts those cases.
- The contracting party is a US corporation Confluent's terms of use name Confluent, Inc. as a Delaware corporation. For a public body, a regulated firm or any buyer with a sovereignty policy, that is the deciding fact, before features or price enter the discussion. The European vendors on this page are registered in Finland, the Netherlands, Germany, Poland, Sweden and the United Kingdom, so the contract sits under their national law, not under Delaware.
- Prices are in dollars and move with usage The pricing page of Confluent states that all prices are in United States dollars unless specifically stated otherwise. Cloud pricing is usage-based, and the entry costs shown for Standard and Enterprise assume about 70% utilization. If your traffic is lower or spikes higher, the monthly figure differs. Aiven bills by the hour per service and Ververica and Axual quote per deployment, which gives you different shapes of cost to compare.
- The vendor now belongs to a bigger group The pricing page header calls Confluent an IBM company. We could not verify what that changes for contracts, roadmap or support, and we do not claim that it changes anything. It is still a reason for a procurement review: the party you negotiated with may not be the party that sets terms in two years. A mid-sized European vendor with a single product line offers a more predictable counterpart.
- You may be buying more platform than you use Many teams run Kafka for one pipeline and pay for a full platform around it. Lenses sells only the developer workspace and replication layer, Ververica and Nussknacker sell only Flink stream processing, and Aiven sells only managed brokers. Splitting the stack lets you pay for the piece you use and swap the others, at the cost of integrating them yourself.
What you have to replace, not just match
Replacing Confluent starts with deciding which layer you actually depend on. Brokers and topics are the core and the easiest part to move, because the Kafka protocol is the same on the other side. Stream processing, governance, replication and the connectors that feed your topics are separate jobs, and each of them has a different European vendor on this page.
For managed brokers, Aiven in Finland is the like-for-like option, with a free Kafka plan and bring-your-own-cloud deployment. For governance, access control and self-service topics, Axual in Utrecht is the closest match. For a developer workspace across clusters, and for replication between them, Lenses in London fills the gap. For Flink-based processing, Ververica in Munich and Nussknacker in Warsaw both work on top of Kafka rather than replacing it.
Four tools on this page are not log-based streaming: CloudAMQP, HiveMQ, Ably and Pusher. They are message brokers or realtime services, and none of them keeps a replayable event log the way Kafka does. If your applications consume old events again, or build state from the log, those four are not replacements. If you only push messages to devices or browsers, they are the lighter and cheaper fit.

How each alternative compares to Confluent
Best for: Teams that want managed Kafka in EU regions with a free entry plan
Aiven Oy is registered in the Finnish commercial register under Business ID 2795743-5, and its terms set Finnish law with arbitration in Helsinki. Against Confluent Cloud it covers the same core need: Kafka that somebody else operates. Services run on AWS, Google Cloud, Azure, DigitalOcean, OVH and UpCloud, with regions that include Frankfurt, Amsterdam and London.
The commercial model differs from Confluent's usage tiers. Aiven bills by the hour per service and says the rate covers infrastructure, operations, backups and upgrades. A free Kafka plan with capped resources and no time limit gives you a place to test a migration before paying. The price of Kafka itself sits on a separate pricing page and was not compared here.
What Aiven does better than Confluent
- Finnish contracting company under Finnish law, not a Delaware corporation
- Free Kafka plan without a time limit
- BYOC deployment inside your own cloud account
- Hourly billing per service that is easy to forecast
Where Aiven is a step down from Confluent
- No bundled governance portal comparable to Axual
- Terms do not name the contracting company; the register entry does
- Free plans are limited to specific providers and regions
Standout against Confluent. The only tool here that matches Confluent Cloud on managed Kafka itself and adds a free plan.
Best for: Organisations that need access rules and self-service topics on EU infrastructure
Axual B.V. is based on Jaarbeursplein in Utrecht. Its governance dashboard controls access, schemas and data flows, and developers manage their own topics and schemas in a self-service portal. Stream processing is available through low-code KSML or Flink SQL under the same governance. Confluent customers who struggle with who may read which topic will recognise the problem Axual targets.
Axual Cloud runs on Scaleway, which the vendor describes as an EU sovereign cloud, and you can also self-manage on-premises or in your own cloud, including air-gapped systems. The price is a quote per deployment. There is no public list and no self-service subscription, so an evaluation means talking to the company first.
What Axual does better than Confluent
- Dutch company with an EU sovereign cloud option
- Governance dashboard built into the platform
- Air-gapped and self-managed deployment possible
- Free local run with Docker Compose for developers
Where Axual is a step down from Confluent
- No public prices and no self-service sign-up
- No free hosted tier
- Quote-based buying slows a first evaluation
Standout against Confluent. Governance and sovereignty in one Dutch platform, at the price of a sales conversation.
Best for: Teams that already run Kafka and want tooling and access control around it
Lenses.io Ltd is an English private limited company registered under number 09975716. It does not provide Kafka brokers. The DevX workspace adds SSO and SAML and role-based access control in the Team edition, and the Multi-Kafka Enterprise tier manages several clusters from one place.
K2K replicates across any Kafka cluster, which makes it useful for a migration away from Confluent: you can mirror topics into a new cluster while consumers still read the old one. The free Community edition covers up to 5 users and K2K Community is limited to 5 partitions per replication job. Prices are shown in dollars without a named currency.
What Lenses does better than Confluent
- Free Community edition for up to 5 users
- Replication across any Kafka cluster, which eases a migration
- Federated management across several clusters
- UK company under English law instead of Delaware
Where Lenses is a step down from Confluent
- No brokers, so you still need a Kafka host
- User caps of 5 and 15 on the lower editions
- Hosting location is not stated on the pages we read
Standout against Confluent. The migration helper: K2K lets you run old and new Kafka side by side.
Best for: Teams whose real need is Flink processing running on Kafka data
Ververica GmbH in Munich builds the VERA engine on Apache Flink. Its Streamhouse architecture combines batch and stream processing under one SQL dialect, and the Data Movement part offers more than 100 connectors, including Flink CDC. Ververica processes streams but does not host Kafka, so it pairs with a broker service from Aiven or Axual.
Deployment is bring-your-own-cloud, with the control plane in your AWS or Azure account, or self-managed on any Kubernetes cluster including on-premises. Pricing is on request and no free trial is listed. The site is inconsistent on a managed cloud model, so confirm that point in writing before you plan around it.
What Ververica does better than Confluent
- German company under German law
- Batch and stream processing in one SQL dialect
- Runs in your own cloud account or air-gapped
- Over 100 connectors including Flink CDC
Where Ververica is a step down from Confluent
- No Kafka hosting, so it replaces only the processing layer
- No public prices and no listed free trial
- Managed cloud offer is unclear on the website
Standout against Confluent. The Flink specialist: it replaces the processing job without forcing a broker decision.
Best for: Teams that want analysts and developers to build Flink scenarios visually
Nussknacker is built by TouK in Warsaw. It offers a visual drag-and-drop designer for Apache Flink scenarios and can deploy real-time machine learning models inside them. The core is open source under Apache 2.0 and is available on GitHub, so you can run it yourself without a licence fee.
The paid SaaS starts with a 3-month free trial by email, then Starter at $480 per month, Professional at $950 and Enterprise at $2,840 per month, in USD excluding VAT. The contracting entity of the SaaS and its region are not named on the pages we read. The open core has no support, so self-hosting means carrying the operations yourself.
What Nussknacker does better than Confluent
- Apache 2.0 core that you can self-host
- Published plan prices from $480 per month
- Visual designer instead of code-only jobs
- Polish builder, not a Delaware corporation
Where Nussknacker is a step down from Confluent
- Does not host Kafka
- Prices in USD, not euros
- SaaS region and contracting entity are not stated
Standout against Confluent. The only processing tool here with both an open-source core and a visible price list.
Best for: Platform teams that run Kubernetes and want Kafka next to other data tools
Stackable GmbH in Wedel, Germany, ships the Stackable Data Platform with Apache Kafka among Trino, Apache Spark, Apache NiFi, Apache Airflow and OpenSearch. It runs on Kubernetes on-premises or in the cloud, and a quick start works through the stackablectl tool. Only software with non-restrictive open-source licences is included.
Kafka here is one app of many, not a dedicated streaming product, so expect less polish around topics than Confluent offers. Commercial plans are Subscription, Managed Data Lakehouse and Expertise, without published prices, and the Managed Data Lakehouse has a 30-day trial. The hosting location of the managed plan is not stated.
What Stackable does better than Confluent
- Free open-source platform with no licence fee
- German company under German law
- Kafka runs next to Trino, Spark and NiFi in one stack
- Runs on-premises under your own control
Where Stackable is a step down from Confluent
- Kafka is not a dedicated product here
- Requires Kubernetes skills from your team
- No published commercial prices
Standout against Confluent. The self-run route: Kafka without a licence fee, if you can operate Kubernetes.
Best for: IoT and industrial teams that send device messages and need no replay
HiveMQ GmbH delivers messages between devices and applications over MQTT. It does not keep a replayable event log the way Apache Kafka does, which is an inference from the product pages. If your Confluent topics carry sensor data that nobody re-reads, HiveMQ is a lighter fit. If they feed analytics from stored history, it is not.
The Lab tier is free for one broker with 25 connections and 25 messages per second. Launch costs $299 per month and Run $499, and fully managed Starter costs from $0.34 per hour plus $0.80 per million messages with a 15-day trial. The country is inferred from the GmbH legal form, and the city is not stated.
What HiveMQ does better than Confluent
- Built for devices, with a free Lab tier for testing
- Self-serve plans with published prices
- Self-managed or fully managed
Where HiveMQ is a step down from Confluent
- Not a Kafka-style event log
- Lab tier is capped at 25 connections
Standout against Confluent. A broker for devices that should not be mistaken for a Kafka log.
Best for: Applications that queue jobs and messages and need no event replay
CloudAMQP, run by 84codes AB, hosts RabbitMQ and LavinMQ brokers in shared and dedicated plans. It is a message broker service, so it fits task queues and service-to-service messages rather than a retained event log. The Kafka service of the same operator, CloudKarafka, is marked as discontinued on its own site.
Two free shared plans exist, and shared paid plans cost $19 per month. Dedicated plans run from $49 to $14,995 per month and are billed by the second, with a VPC add-on at $99 per month. Free instances with no messages for two months are deleted after a warning email. Sweden is inferred from the AB form and Swedish governing law.
What CloudAMQP does better than Confluent
- Per-second billing on dedicated plans
- Free shared plans for small queues
- Five cloud providers listed, including Scaleway
Where CloudAMQP is a step down from Confluent
- Not a log-based streaming platform
- Idle free instances are deleted after two months
Standout against Confluent. The cheapest way to run a queue broker, provided you do not need Kafka semantics.
Best for: Products that push live updates to users with channels and presence
Ably Realtime Ltd, a UK company, offers channels, presence and connections with SDKs. It does not replace a Kafka event log, which is an inference from the product. Think of it as the layer that delivers an event to a user interface, rather than the system of record that stores events.
The free plan costs $0 and includes 6M messages per month, 1 day of message storage and a 64 KiB cap per message. Standard is $29 per month plus usage and Pro $399 per month plus usage, with messages at $2.50 per million. Region and hosting are not stated on the pricing page, and the dollar figures carry no currency code.
What Ably does better than Confluent
- Free plan with 6M messages per month
- Published usage prices per million messages
- Channels and presence built for end-user apps
Where Ably is a step down from Confluent
- Not a durable event log
- Free plan keeps messages for only 1 day
- UK company; hosting region not stated
Standout against Confluent. Good at pushing events to users, and not designed to store them.
Best for: Web and mobile apps that need simple live updates at a predictable price
Pusher Limited is registered in England and Wales under number 07489873. Pusher Channels offers a publish and subscribe API with daily message limits and concurrent-connection limits. It is not a durable event streaming log, so it cannot stand in for Confluent topics that consumers replay.
The Sandbox tier is free with 200k messages per day and 100 connections. Paid tiers are fixed monthly plans from $49 to $1,199, Enterprise is a custom quote, and Priority support starts at $3,000 per month. Plans are prorated when you change them in the dashboard. Hosting region is not stated on the pricing page.
What Pusher does better than Confluent
- Fixed monthly tiers that are easy to forecast
- Free Sandbox tier
- Simple API for live updates
Where Pusher is a step down from Confluent
- Not a durable event log
- Priority support from $3,000 per month
Standout against Confluent. The most predictable price on the page, for the narrowest job.
What actually breaks when you switch
The first thing that breaks is the assumption that every tool here is Kafka. Aiven, Axual and Stackable run Kafka, so clients keep working with new connection details. The four brokers and realtime services speak other protocols, so applications need new code, not a changed hostname.
Second, the surrounding layers: schemas, access rules, connectors and processing jobs were built against Confluent's setup and have to be recreated or exported. Run the new cluster in parallel, mirror topics with a replication tool such as Lenses K2K, and move consumers one group at a time. Check the termination and notice terms in your Confluent contract before you set a date, because we could not read them for you.
Can I move off Confluent without leaving Kafka?
Yes, if what you run is Apache Kafka. Aiven, Axual and Stackable all offer Kafka itself, so clients that speak the Kafka protocol keep working once you change the connection details. Aiven runs it as a managed service, Axual adds governance on top, and Stackable ships it as one app among many on Kubernetes.
The harder work is everything around the brokers: topic and schema definitions, access rules, connectors and any processing jobs. Plan the move per layer and run old and new side by side. Lenses can replicate between Kafka clusters with its K2K product, which gives you a way to mirror topics during the cutover.
Which tool on this page is not a Kafka replacement?
CloudAMQP, HiveMQ, Ably and Pusher are the four. CloudAMQP hosts RabbitMQ and LavinMQ brokers, and the Kafka hosting service of the same operator is marked as discontinued on its own site. HiveMQ is an MQTT broker for device messaging. Ably and Pusher are publish and subscribe services built around channels.
They solve a neighbouring problem: delivering a message now, to a device or a browser, without keeping history. If your Confluent topics act as a durable record that consumers replay, choose among Aiven, Axual or Stackable for the log, and add Lenses, Ververica or Nussknacker for the tooling around it.
Which one to pick
If you want managed Kafka with the least change, take Aiven. If you need governance and a sovereign cloud and accept a sales process, take Axual. If you run Kubernetes and prefer to operate Kafka yourself, take Stackable, and add Lenses if you want tooling and replication across clusters.
If your Confluent bill is mostly stream processing, Ververica or Nussknacker replaces that layer. If you only deliver messages to devices or browsers, HiveMQ, CloudAMQP, Ably or Pusher cost less, and none of them replaces a Kafka log.
Frequently Asked Questions
For managed Apache Kafka, Aiven from Helsinki is the closest match, with a free Kafka plan and BYOC. For governance and self-service on an EU sovereign cloud, Axual from Utrecht. For Flink stream processing, Ververica from Munich or Nussknacker from Warsaw. Lenses from London adds a developer workspace across clusters.
Partly. Aiven has a Kafka free plan with capped resources, Lenses has a free Community edition for up to 5 users, and Nussknacker has an Apache 2.0 open-source core and a 3-month free trial. Stackable is free as an open-source platform. Axual is free only for a local run with Docker Compose, not as a hosted trial.
Confluent's own terms name Confluent, Inc., a Delaware corporation, as the contracting party. The header of its pricing page describes Confluent as an IBM company. We checked both pages on 3 November 2026 and did not read further into the ownership structure, so we make no claim about control, voting rights or contract changes.
Two on this page lean open source. Nussknacker publishes its core under Apache 2.0, though that core has no support and no enterprise integrations. Stackable includes only software with non-restrictive open-source licences and runs Kafka on Kubernetes, which requires Kubernetes skills from your team.
Several options say where they run. Aiven lists regions including Frankfurt, Amsterdam and London, Axual Cloud runs on Scaleway, and Ververica, Nussknacker and Stackable support deployment in your own cloud account or on-premises. Lenses, Ably, Pusher and Nussknacker's SaaS do not state a region on the pages we read.
Not always. If you send updates to browsers or devices and never replay old messages, a broker or realtime service such as HiveMQ, CloudAMQP, Ably or Pusher is smaller and cheaper. If consumers need to re-read history, build state from the log or reprocess data, you need a log-based platform.
