Comparison · facts verified 2026-09-07
The closest overlap, with a different trust boundary. Copilot coding agent takes an Issue assignment and works in a GitHub cloud sandbox before opening a pull request. Orbi runs the delivery loop on your machine, with your model endpoint and GitHub as the record. Both reduce hands-on coding; the choice is who owns execution, models, cost, and evidence.
THE COMPETITOR, FROM OFFICIAL MATERIALS
GitHub documents coding agent as an agent that can be assigned an Issue by mentioning @copilot. It works autonomously in a GitHub-hosted ephemeral development environment, creates a branch, and opens a pull request for review. GitHub says it is included with eligible Copilot plans and works alongside the repository's normal review workflow. It is a convenient cloud service, not a locally operated or source-auditable delivery runner.

DIFFERENCES THAT DECIDE THE CHOICE
| Dimension | Orbi | Copilot coding agent |
|---|---|---|
| Task entry | GitHub Issue plus ai-ready label; queue and priority are yours | Mention @copilot in an Issue; GitHub assigns the cloud agent |
| Models | BYOK: any OpenAI-compatible endpoint, including free tiers | Models and available choices are governed by GitHub/Copilot |
| Runs where | Your machine: repository, keys, tests, and state stay local | GitHub-hosted cloud sandbox; code is already in GitHub, but execution is remote |
| Cost | Your hardware and model spend; self-hosted core has no platform fee | Requires an eligible Copilot subscription (the cited plans were $10–39/month/person at verification); plan limits and future pricing are GitHub's policy |
| Auditability | Open-source delivery chain and GitHub evidence can be inspected | PR evidence is visible in GitHub, while the hosted agent implementation is not |

THE VENDOR RISK, STATED PLAINLY
Copilot is a sensible choice when the repository already lives on GitHub: the incremental data boundary is smaller than moving that repository to a new service. But subscription prices (the cited plans were $10–39/month/person), included usage, model availability, sandbox permissions, and retention policy are vendor-controlled and can change. Orbi trades zero-install convenience for local ownership: you choose the endpoint and can inspect the whole chain. Neither is universally better; the right boundary depends on your requirements.

OPEN SOURCE CORE
Copilot removes setup. Orbi keeps the delivery system in your hands. Both can start from a GitHub task; only one is designed to run on your machine with your model.
