Today we are announcing the Devin Open Source Initiative.
As part of Devin’s general availability launch, we’re giving selected open source maintainers 500 free ACUs on a Devin Teams plan. Sign up now at app.devin.ai and reach out to us at osi@cognition.ai to be included.
Open source projects often have a long backlog of issues. There are so many little things to fix that maintainers can quickly become overwhelmed. Devin is the ideal partner on these tasks — by working on minor tasks in the background, Devin helps the maintainers focus on the critical tasks.
Below are some OSS contributions Devin has already helped to make:
Pull request: https://github.com/modelcontextprotocol/inspector/pull/105
Devin session: https://app.devin.ai/sessions/266955553baf40cfa7fdd32d42ab219d
Here Devin works on the inspector project, a debugging UI for MCP servers, to add a new feature for displaying the capabilities negotiation.
Issue: https://github.com/modelcontextprotocol/inspector/issues/85
Devin first uses the browser to research how capability negotiation works:
After Devin writes the code, a few key Devin features enable proper testing:
- Repo setup. Before starting Devin sessions, we set up Devin’s VM by installing
uvfor Python MCP servers. - Knowledge. We can either tell Devin manually how to test the code, or add this to its knowledge base so that Devin automatically remembers in future sessions.
Given this setup, Devin can verify that the code changes work in the browser:
The code, now tested, is ready for the maintainer to review.
Pull Request: https://github.com/dagger/dagger/pull/9130

Devin’s PR addresses a low-priority task in the Dagger project.
While it’s impressive that Devin is able to eventually solve the issue, several rounds of back and forth are sometimes needed.
Devin’s Github integration works with PR comments and CI checks to make this process smoother. Any PR comments are automatically sent to Devin by a webhook.
Finally, to get the most out of Devin, don’t expect 100% perfect PRs. While Devin can get you 80% of the way there, a human should still ensure quality of the final result. This means e.g. removing stray diffs before merging. In this PR, Devin added debugging logs which will later need to be removed.

We had Devin contribute to many more open source repos, including:
