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.; Bazel steep learning curve for developers unfamiliar with build systems
  • They diverge on capability: Activiti covers BPMN 2.0 engine, Bazel covers Fast incremental builds.
  • 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.

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.

Bazel

  • Steep learning curve for developers unfamiliar with build systems
  • Initial setup complexity; requires BUILD files and Bazel configuration
  • Verbose error messages can be difficult to debug for new users
  • Smaller community and fewer third-party integrations vs enterprise tools

Can I use Activiti for free?
Both have a free tier, so you can try either at no cost before committing.
What is Activiti best used for?
Activiti is most often used for an alfresco or hyland content services deployment where activiti is already the embedded workflow engine, a java application that needs to embed a bpmn engine as a library under a permissive licence, an organisation that has ruled out camunda 8 on licence grounds and needs an apache 2.0 alternative, document-centric approval workflows where the process engine sits inside the content management stack rather than beside it. Of those, an alfresco or hyland content services deployment where activiti is already the embedded workflow engine and a java application that needs to embed a bpmn engine as a library under a permissive licence are not what Bazel is typically brought in for.

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.

Bazel: Does Bazel support distributed builds across CI infrastructure?

Yes, Bazel supports distributed execution and remote caching, allowing build work to be distributed across multiple machines and CI agents.

Source
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.

Bazel: What languages can be built with Bazel?

Bazel has built-in support for Java, C++, Go, Python, and Android/iOS development, with additional language support available through custom rules and community extensions.

Source
Activiti: What licence is it?

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

Bazel: Can I use Bazel for small projects or is it only for large monorepos?

While Bazel excels at handling large projects, it can be used for smaller codebases. However, the setup overhead may not be justified for very small or simple projects.

Source
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.
