Comparison · facts verified 2026-09-24
The closest overlap, with a different trust boundary. Copilot cloud agent (formerly Copilot coding agent) takes an Issue assignment, works in a GitHub cloud sandbox, and can open a pull request. Orbi runs the delivery loop self-hosted on your machine or on an Orbi Cloud hosted runner, with your configured 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 cloud agent as an agent that can be started from an Issue assignment, the agents panel, Copilot Chat, VS Code, a pull request comment such as @copilot, Slack, or Teams; automations can also trigger it on a schedule or event. It works autonomously in a GitHub-hosted ephemeral development environment, creates a branch, and can open a pull request for review. GitHub says it is included with paid Copilot plans, but cloud agent usage also consumes GitHub Actions minutes and AI credits. Some rulesets and branch protection rules are incompatible with cloud agent and can block it unless Copilot is added as a bypass actor. It is a convenient cloud service, not a locally operated or source-auditable delivery runner.

DIFFERENCES THAT DECIDE THE CHOICE
| Dimension | Orbi | Copilot cloud agent |
|---|---|---|
| Task entry | GitHub Issue plus ai-ready label; queue and priority are yours | Issue assignment, agents panel, Chat, VS Code, PR @copilot, Slack/Teams, or scheduled/event automations |
| Models | BYOK: any OpenAI-compatible endpoint; provider terms vary | Models and available choices are governed by GitHub/Copilot |
| Runs where | Self-hosted: execution and state run on your machine; code goes to your configured model endpoint unless you use a local model. Orbi Cloud runs on a hosted runner | 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 | Paid Copilot subscription (the cited plans were $10–100/month/person at verification), plus cloud agent usage of GitHub Actions minutes and AI credits; limits and future pricing are GitHub's policy |
| Auditability | Open source (AGPL-3.0) delivery chain and GitHub evidence can be inspected | PR evidence is visible in GitHub, while the hosted agent implementation is not source-auditable |

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 $10–100/month/person), Actions-minute and AI-credit usage, model availability, sandbox permissions, and retention policy are vendor-controlled and can change. Orbi trades zero-install convenience for control of the execution boundary: self-hosted runs use your machine, while Orbi Cloud uses a hosted runner; code is sent to the model endpoint you configure unless you use a local model. Neither is universally better; the right boundary depends on your requirements.

AN HONEST READ
IF YOU ARE REPLACING COPILOT
Copilot is two products behind one subscription, and its alternatives divide along the same seam. One surface completes and chats inside your editor; the other starts from a GitHub Issue and opens a pull request. The four tools in the table replace the first surface, each described from its own documentation. Orbi replaces the second, and carries the task past the pull request to an independent review, the merge and the release.
REPLACING THE EDITOR ASSISTANT
| Choose this when | Tool | What its own documentation says |
|---|---|---|
| You want the agent in the same window as the code | Cursor | Its Agent takes on a coding task in a side pane, edits files and runs terminal commands where the code lives. |
| You already work in Windsurf | Windsurf (now Devin Desktop) | Cognition's FAQ dates the rename to 2026-06-02 and says it is the same IDE, the same editor and the same features under the Devin brand. |
| You want to approve every action | Cline | A coding agent inside the editor and the terminal that reads files, writes code and runs commands, asking for approval at each step. |
| Completion and chat must stay on your infrastructure | Tabnine | A private, organization-aware agent with completion, chat and a CLI, built to run inside your own deployment. |

REPLACING THE CLOUD AGENT
Orbi starts from an ai-ready Issue and does not stop at the pull request: it runs the coding session, reviews its own frozen head in a separate session, merges only that head, and tags the release. The same boundary is measured against other runners in Orbi vs Claude Code, Orbi vs OpenAI Codex and Orbi vs OpenHands. You need not take that on faith: the sibling Claude Code alternatives section on this site went through the loop — Issue #869 in, PR #880 out, merged by the orbi-build app with no human review — and more deliveries are indexed on the evidence page.

OPEN SOURCE (AGPL-3.0) 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.
