OpenRocket is developed and maintained entirely by volunteers in their free time. Every contribution — whether code, documentation, translations, testing, or design examples — directly improves the tool for the entire rocketry community.

​
Ways to contribute

Code

Fix bugs, implement new features, or improve existing functionality. The source code is on GitHub and contributions are made via pull requests.

Documentation

Help improve or expand this documentation. If you notice something missing or incorrect, you can contribute directly. See the Developer Guide for instructions.

Translations

Help translate the OpenRocket interface into other languages via the OpenRocket Crowdin project. Translations are community-maintained and many are incomplete.

Testing

Test pre-release versions of OpenRocket and report bugs on the GitHub issue tracker. Pre-release testing helps catch last-minute issues before a stable release.

Example designs

Create well-documented example rocket designs that demonstrate OpenRocket features and can be bundled with the application.

Bug reports

Report bugs or request features on the GitHub issue tracker. Detailed, reproducible bug reports are extremely valuable.

​
Getting started

The best place to start is the OpenRocket contribute page and the CONTRIBUTING.md file in the repository. These describe the practicalities of submitting code, the development workflow, and the project’s conventions. For questions and discussion with other contributors, join the OpenRocket Discord server.
