BPMN-Process Automation for Everyone

Home

Operaton is a community-driven, free, and open-source BPMN engine.

It inherited its source code from the legacy of Camunda, Activiti and their predecessors. Camunda 7 was an important contribution to the open-source BPMN community. Building on this legacy, we aim to create a thriving future for a truly free and open-source BPMN engine.

Our Promise

  • Operaton is a state-of-the-art BPMN engine
  • Forever free and open source under the Apache 2.0 license
  • Community-owned by a legal foundation (currently in progress)
  • The trademark Operaton will be owned by the instituted legal foundation
  • Source Code
  • Documentation
  • Forum
  • Chat (Slack)

    Features & Goals
    • Easy migration from Camunda 7 (see Documentation and OpenRewrite scripts)
    • Up-to-date dependencies (e.g. increased Java and Spring base versions)
    • Focus on security and stability
    • Completely new web apps, rewritten with accessibility, usability and performance in mind
    • Improved documentation (see Documentation)
    • An inclusive and welcoming community (join the Forum and Chat (Slack))
    • Contributions are welcome

    Principles
    Community ownership
    Operaton shall always be a community-owned free open-source project (legal work in progress). There shall be no private or commercial entity which is able to legally claim its ownership or divert the goals of the community. See our Code of Conduct to learn how we foster an open, welcoming, diverse, inclusive, and healthy community.
    Quality
    It shall be held to high-quality standards regarding every aspect: SonarQube activtities and GitHub issues.
    Transparency
    Operaton is developed in the open. All decisions are transparently made by its community for its community.
    Self ownership
    There shall be no hidden dependencies making it hard to build it on your own. Everything is easy to run by yourself.

    Roadmap

    We want to keep Operaton users informed and know what to expect next and when. This also shall show where the current priorities of the contributors lie. If you have other priorities you may share them in our forum or contribute changes yourself (with the help of the community).
