Orbi — GitHub issue delivery with independent review, fixes, merge and separate release tasks.

About Orbi

Orbi is a GitHub App (Cloud) and an open-source delivery engine you can self-host. It is for developers and small teams that use GitHub issues to define changes and want the resulting code independently reviewed and merged.

Label an issue ai-ready. An AI agent implements it in an isolated workspace, then Orbi pushes a branch and opens a pull request. A separate AI review session finds problems, fixes the code and reruns tests. Before merging, Orbi requires the review and CI to pass. Releases are separate: create a Release task when you want Orbi to update the version, create tags and publish a GitHub Release.

Start with a small change whose expected result you can check, such as a reproducible bug. Put the goal and acceptance criteria in the issue, then inspect the resulting diff, review fixes and test results. Use that delivery to assess the workflow in your own repository before increasing the scope.

Cloud provides the hosted GitHub App and includes 3 deliveries free, no credit card. Self-hosting the engine is free under AGPL-3.0 or the alternative Sustainable Use License. You provide your own model access and operate the runtime; model and infrastructure costs depend on your setup. Read the selected license before redistributing Orbi or offering it as a service.

Who it is for
Developers and small teams that define changes in GitHub issues.
Problem it solves
AI-written code still needs independent review, fixes, tests, merging and release coordination.
The solution
Orbi implements ai-ready issues in isolated workspaces and merges after independent review and CI pass.
What makes it unique
A separate AI review session fixes findings and reruns tests. Release tasks run separately. The engine is self-hostable under AGPL-3.0 or the Sustainable Use License.

What do DR4, DR3 and the model difference mean?
DR4:
Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
DR3:
The previous model, shown in the Ahrefs app until 1 December 2026.
Model difference:
DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
