The short version

  • Only Decodable has a free tier, so it costs nothing to try first.
  • Each has a real cost: Camunda camunda 7 Community Edition stopped receiving security patches after the 7.24 release in October 2025, so free production deployments are now running unpatched software.; Decodable credit pricing rewards intermittent work and penalises always-on pipelines: a single small task running continuously costs roughly 86 US dollars a month before any parallelism.
  • They diverge on capability: Camunda covers BPMN 2.0 execution, Decodable covers Managed Flink.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Camunda

  • Camunda 7 Community Edition stopped receiving security patches after the 7.24 release in October 2025, so free production deployments are now running unpatched software.
  • Camunda 8 Self-Managed is source-available under the Camunda License 1.0, not open source: production use requires a paid licence, and organisations that adopted Camunda for its Apache licence have to renegotiate that decision.
  • Migrating from Camunda 7 to 8 is a rewrite rather than an upgrade because the engine, the API and the persistence model all changed, and there is no in-place migration for running instances.
  • Camunda 8 Self-Managed has substantial infrastructure requirements including Zeebe brokers, Elasticsearch and Identity, which is a considerable operations burden compared with the single database that Camunda 7 needed.
  • Pricing is not published at all, so evaluating total cost requires a sales process, and there is no way to size a budget before committing engineering time to a proof of concept.

Decodable

  • Credit pricing rewards intermittent work and penalises always-on pipelines: a single small task running continuously costs roughly 86 US dollars a month before any parallelism.
  • Parallelism multiplies tasks, so scaling a pipeline to keep up with throughput multiplies the bill in a way that is easy to under-forecast at design time.
  • The free tier retains streams for only 24 hours, which is too short to debug an intermittent failure that surfaces days later.
  • Java and Python transformations are gated behind paid plans, so anything the SQL layer cannot express means moving off the free tier immediately.
  • The operational layer is proprietary even though Flink and Debezium are not, so migrating to self-managed Flink later means rebuilding connectors, schema handling and monitoring from scratch.

Answered from the vendors’ own pages

Camunda: Is Camunda still open source?

No. Camunda 8 Self-Managed ships under the Camunda License 1.0, which is source-available and requires a paid production licence.

Decodable: What is a credit worth?

0.12 US dollars on On Demand and 0.10 on Enterprise. A small task consumes one credit per hour, medium two, large four.

Camunda: What happened to Camunda 7?

Its final feature release, 7.24, was in October 2025 and the Community Edition receives no further patches. Enterprise support runs to April 2030.

Decodable: Is there a free plan?

Yes, up to four concurrent tasks with 24 hour or 10 GB stream retention.

Camunda: Can I upgrade from 7 to 8?

Not in place. The engine, API and persistence changed, so it is a rewrite of the integration layer.

Decodable: Is it really Apache Flink underneath?

Yes, Flink for processing and Debezium for change data capture, both managed by Decodable.

Camunda: What does it cost?

Camunda does not publish prices. Both self-managed production and SaaS require a quote.

Decodable: Can I run my own Flink jobs?

Yes, Java and Python jobs on paid plans; the free plan is SQL only.
