// Competitive Comparison
Confluent Alternatives Compared
Confluent Platform is Apache Kafka plus components under Confluent's own licences, and IBM has owned Confluent since March 2026. These are the supported ways to run Kafka without it, what each one gives up, and where OSSeva fits.
Where OSSeva is stronger
- ✓Patched community Apache Kafka builds for 2.x and 3.x lines, including ZooKeeper-mode clusters
- ✓Support for Kafka 3.8 and 3.9 after Confluent Platform 7.8 and 7.9 standard support ends
- ✓Runs where your Kafka runs today: your data centre, your cloud account or Kubernetes
- ✓24/7 managed operations with a 15-minute P1 SLA on the Operate tier
- ✓Migration design for replacing Confluent Platform components such as Schema Registry and commercial connectors
Where Confluent is stronger
- →Confluent Cloud, a fully managed Kafka service that OSSeva does not run
- →Confluent-built components: Schema Registry, ksqlDB, Control Center and commercial connectors
- →Up to three years of patches per Confluent Platform minor release on the Enterprise licence
- →The backing of IBM, which completed its acquisition of Confluent on 17 March 2026

Alternatives compared
| Option | What it is | Best for |
|---|---|---|
| Self-managed Apache Kafka with OSSevaDetails | Patched community Apache Kafka 2.x and 3.x builds, including ZooKeeper-mode clusters, on your own infrastructure. 24/7 operations on the Operate tier and migration design off Confluent components such as Schema Registry. | Teams that want to keep running Kafka themselves, including versions Confluent no longer covers. |
| Instaclustr (NetApp)Source | Managed open source Apache Kafka in the cloud or on-premises, and support for Kafka clusters you run yourself. | Teams that want a managed service that is not tied to one public cloud. |
| Amazon MSKSource | AWS's managed Apache Kafka, in ZooKeeper or KRaft mode. AWS says a cluster on a Kafka version past its end of support date is auto-upgraded, at any time and without notification. | AWS-only workloads where AWS can operate the brokers and decide upgrade timing. |
| StrimziSource | A Cloud Native Computing Foundation incubating project that deploys and operates Apache Kafka on Kubernetes. Open source with no SLA of its own. | Kubernetes platform teams, usually paired with commercial support for the Kafka clusters it runs. |
| RedpandaSource | A Kafka API compatible broker written in C++, not Apache Kafka. Community Edition is under the Redpanda Business Source License, which converts to Apache 2.0 four years after release. Tiered Storage, audit logging and RBAC need an Enterprise licence. | New deployments that can test client behaviour against a different broker implementation. |
| Aiven for Apache KafkaSource | Managed upstream Apache Kafka on AWS, Google Cloud and Azure, with a Karapace schema registry and a Bring Your Own Cloud option. | Teams that want a managed service across clouds, with an open source Schema Registry replacement. |
Why teams choose OSSeva
Supported Apache Kafka without the platform
OSSeva patches upstream community Apache Kafka. Kafka, Kafka Connect and Kafka Streams are Apache 2.0, so your cluster keeps running the runtime you already deploy, with security fixes backported to the version you are on. There is no proprietary distribution to adopt and nothing to migrate just to start support.
The versions Confluent's calendar leaves behind
Confluent Platform 7.8 (Kafka 3.8) leaves standard support on 2 December 2026 and 7.9 (Kafka 3.9) on 19 February 2027. Confluent Platform 7.x is also the last line that runs on ZooKeeper. OSSeva covers those Kafka versions and the ZooKeeper ensembles behind them after the dates pass, so the move to KRaft and Kafka 4.x happens on your schedule.
Operations and the exit, under one contract
The Operate tier adds 24/7 monitoring and incident response with a 15-minute P1 SLA. The migration work covers the parts of an exit that take time: replacing Schema Registry and commercial connectors, the KRaft migration, and a blue-green cutover between clusters.
Why teams choose Confluent
The broadest commercial Kafka ecosystem
If your applications depend on Schema Registry, ksqlDB, Control Center or Confluent's commercial connectors, Confluent remains the simplest way to keep them. Replacing those components is the largest part of any exit, and some teams decide it is not worth it.
Confluent Cloud for teams that want no brokers at all
Confluent Cloud runs Kafka on Confluent's infrastructure. If the goal is to stop operating Kafka entirely rather than to keep self-managed clusters supported, it is a strong option that OSSeva does not replicate.
Which is right for your situation?
Choose OSSeva when…
You want to keep running Apache Kafka yourself, on-premises, in your own cloud account or on Kubernetes, with security patches for the versions you have, including ZooKeeper-mode 2.x and 3.x clusters, and with 24/7 operations or migration help when you need them.
Talk to an engineerConsider Confluent when…
Your applications rely on Confluent-licensed components such as ksqlDB or commercial connectors, you are on a Confluent Platform release inside its support window, or you want a fully managed service on the vendor's infrastructure.
OSSeva covers community Apache Kafka 2.x and 3.x, including after Confluent Platform 7.x support dates. Confluent covers its own distribution for up to three years per minor release.
Frequently asked questions
What are the main Confluent alternatives?
There are five common routes. Self-managed Apache Kafka with commercial support from a provider such as OSSeva or Instaclustr. Amazon MSK, AWS's managed Apache Kafka. Strimzi, which runs Kafka on Kubernetes. Redpanda, a Kafka API compatible platform that is not Apache Kafka. And managed Apache Kafka services such as Aiven for Apache Kafka. The right one depends on whether you want to keep operating Kafka yourself and which Confluent components you use.
When does Confluent Platform 7.x support end?
Per Confluent's version support page: 7.7 (Kafka 3.7) left standard support on 26 July 2026, with Platinum support to 26 July 2027. 7.8 (Kafka 3.8) leaves standard support on 2 December 2026, Platinum on 2 December 2027. 7.9 (Kafka 3.9) leaves standard support on 19 February 2027, Platinum on 19 February 2028. Confluent Platform 8.x ships Kafka 4.x, which no longer supports ZooKeeper.
Who owns Confluent now?
IBM. It completed its acquisition of Confluent on 17 March 2026.
Is OSSeva a Kafka fork?
No. OSSeva patches are applied to upstream community Apache Kafka source code. Your cluster runs Apache-licensed Kafka, with no OSSeva-specific APIs, no proprietary configuration format and no runtime components that differ from community Kafka.
How does OSSeva handle Kafka's move from ZooKeeper to KRaft?
OSSeva supports both ZooKeeper-mode and KRaft-mode clusters. EOL support covers the ZooKeeper-dependent 2.x and 3.x versions, and the architecture work includes KRaft migration planning for teams ready to move off ZooKeeper.
