Orbi

Orbi is an open-source coding agent that takes GitHub issues all the way to a release. A developer labels an issue ai-ready, Orbi writes the change in an isolated worktree and opens a pull request, a second AI session checks the pull request against the issue's acceptance criteria and fixes what fails, and only the reviewed commit is merged before Orbi tags the release through the repository's own release process. Issues labelled ai-ops-only run deploys or investigations and post the commands and output back on the issue. It runs on the model of your choice.

Self-hosting is free under AGPL-3.0 with your own model key. Orbi Cloud includes three merged deliveries free. Solo is US$29 a month or US$290 a year (US$24 a month billed yearly) for one repository, and Pro is US$79 a month or US$790 a year for five repositories.

Teams comparing autonomous coding agents that work from GitHub issues can also look at OpenHands, an open-source agent with a free cloud tier, and Devin, which plans, codes and opens pull requests in the cloud. Teams that want Google's asynchronous coding agent can look at Jules.
