Operaton is a native BPMN 2.0 process engine that runs inside the Java Virtual Machine.
It can be embedded inside any Java application and any runtime container.
It integrates with Spring, Spring Boot, Quarkus and is a perfect match for Jakarta EE.
On top of the process engine, you can choose from a stack of tools for human workflow management, operations and monitoring.
Operaton is the successor of the Camunda 7 BPM platform that went EoL in October 2025.
Release 1.0 is feature complete and fully compatible with Camunda 7.24.

## About Operaton
### Components
Operaton provides a rich set of components centered around the BPM lifecycle.
#### Process Implementation and Execution
- Operaton Engine - The core component responsible for executing BPMN 2.0 processes.
- REST API - The REST API provides remote access to running processes.
- Spring, CDI Integration - Programming model integration that allows developers to write Java Applications that interact with running processes.
#### Process Operations
- Operaton Engine - JMX and advanced Runtime Container Integration for process engine monitoring.
- Operaton Cockpit - Web application tool for process operations.
- Operaton Admin - Web application for managing users, groups, and their access permissions.
#### Human Task Management
- Operaton Tasklist - Web application for managing and completing user tasks in the context of processes.
### Highly Integrable
Out of the box, Operaton provides infrastructure-level integration with Java EE Application Servers and Servlet Containers.
### Embeddable
Most of the components that make up the platform can even be completely embedded inside an application. For instance, you can add the process engine and the REST API as a library to your application and assemble your custom BPM platform configuration.
### Process modelling
Operaton is fully backwards compatible to your existing BPMN-, DMN-models and Forms, which were created in Camunda Modeler for Camunda 7. You can download the Camunda Modeler [here](https://camunda.com/download/modeler/) (MIT Licence).
## Get it!
Get the latest release from the [Releases page](https://github.com/operaton/operaton/releases).
To get the latest stable build visit the [Early Access release page]([https://github.com/operaton/operaton/actions/workflows/nighly-build.yml?query=branch%3Amain+event%3Aschedule+is%3Asuccess++](https://github.com/operaton/operaton/releases/tag/early-access)), click on _Assets_ and download the desired package.
## Development
### Building
Prerequisites: JDK 17 or newer - check `java -version`
Operaton is tested and supported on Java 17, 21, and 25.
You can use the Maven Wrapper script to execute the build. The script downloads and installs (if necessary) the required Maven version to `~/.m2/wrapper` and runs it from there.
On Linux and MacOS, run
```shell
./mvnw
```
On Windows, run
```shell
mvnw
```
Alternatively, you can use your own Maven installation (minimal version: 3.9.0) Wrapper and execute
```shell
mvn
```
For a faster build you can add `-DskipTests` to skip test execution and `-Dskip.frontend.build=true` to skip the build of the webapps.
