The short version

  • Each has a real cost: Activiti the last stable release was 8.2.0 in January 2024, and while release candidate builds continue, a two-year gap between stable versions is a real risk signal for a production dependency.; OpenSearch diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • They diverge on capability: Activiti covers BPMN 2.0 engine, OpenSearch covers Full-text search.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Activiti

  • An Alfresco or Hyland content services deployment where Activiti is already the embedded workflow enginenot OpenSearch
  • A Java application that needs to embed a BPMN engine as a library under a permissive licencenot OpenSearch
  • An organisation that has ruled out Camunda 8 on licence grounds and needs an Apache 2.0 alternativenot OpenSearch
  • Document-centric approval workflows where the process engine sits inside the content management stack rather than beside itnot OpenSearch

OpenSearch

  • Log and observability storage where an Apache-2.0 licence is a requirementnot Activiti
  • Replacing Elasticsearch after the licence change without changing architecturenot Activiti
  • Search plus analytics on one cluster rather than two systemsnot Activiti

Where each one falls short

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

Activiti

  • The last stable release was 8.2.0 in January 2024, and while release candidate builds continue, a two-year gap between stable versions is a real risk signal for a production dependency.
  • Both Camunda and Flowable forked away and took large parts of the contributor base with them, so the community, tutorials and third-party tooling around Activiti are much thinner than around either fork.
  • Commercial support is only realistically available by buying Hyland Alfresco subscriptions, so there is no way to pay for Activiti support on its own.
  • Activiti Cloud imposes a distributed architecture of several Spring Boot services plus Keycloak, which is heavy for teams who simply wanted an embeddable engine.
  • Documentation is dated and partly split between old Alfresco sites and Hyland Connect, and the transition between Activiti 6, 7 and 8 architectures makes much of the older material actively misleading.

OpenSearch

  • Diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • Operationally heavy in the way Elasticsearch is: cluster sizing, shard strategy and JVM tuning are ongoing work
  • Smaller ecosystem of third-party tooling than Elasticsearch, which most integrations still target first
  • Overkill for plain application search, where a dedicated search engine is far simpler

Answered from the vendors’ own pages

Activiti: Is Activiti still maintained?

Yes, Hyland continues to publish builds, but the last stable release was 8.2.0 in January 2024.

OpenSearch: Is OpenSearch free?

Yes, Apache 2.0 licensed under the Linux Foundation. Amazon OpenSearch Service is a paid managed option.

Activiti: What is its relationship to Camunda and Flowable?

Both are forks of Activiti: Camunda in 2013 and Flowable in 2016, when core developers left Alfresco.

OpenSearch: Why does OpenSearch exist?

Elastic moved Elasticsearch off the Apache 2.0 licence in 2021. AWS forked the last Apache-licensed version, and the project now sits under the Linux Foundation.

Activiti: What licence is it?

Apache 2.0, which distinguishes it from Camunda 8’s source-available licence.

OpenSearch: Is OpenSearch compatible with Elasticsearch?

It was at the 7.10 fork point. Both have developed independently since, so compatibility weakens with every release and should be verified for the features you use.

Activiti: Should I choose Activiti for a new project?

Only if the Apache licence or an existing Alfresco deployment is decisive. Flowable and Camunda have far larger ecosystems.
