Orbi
Orbi is an open-source (AGPL-3.0) software factory for GitHub repositories. When you label a GitHub Issue ai-ready, Orbi implements it in an isolated worktree, opens and reviews pull requests in a separate AI review session that checks acceptance criteria and repairs failing tests, merges the exact reviewed commit SHA, and cuts a tagged GitHub Release when a human applies the ai-release label.

What is Orbi?
Orbi is an open-source software factory for GitHub repositories that turns labelled GitHub Issues into reviewed, merged pull requests and tagged releases. When a maintainer adds the ai-ready label to an Issue, Orbi spins up an isolated git worktree, runs a coding agent (such as Claude Code or Codex) to implement the change and open a pull request, and then launches a separate, independent AI review session with fresh context to verify every acceptance criterion and repair failing checks.
Rather than letting the implementation agent grade its own work, Orbi enforces a six-point merge gate—requiring an explicit reviewer verdict, satisfied acceptance criteria, green CI checks, a clean branch and an exact commit-SHA match between the reviewed revision and the merge target. Teams can self-host Orbi for free with Docker or Node.js 22+ using their own model keys, or use Orbi Cloud with a GitHub App install.
