KeelenCompare — Keelen vs GitHub Copilot
Copilot helps you type. Keelen works while you don't.
GitHub Copilot and Keelen sit at different layers of the stack. Copilot is a pair-programming assistant: it lives in your editor and accelerates the code you are actively writing. Keelen is an autonomous coding loop: it holds your product roadmap and runs against your GitHub repository around the clock — planning tasks with acceptance criteria, writing code in isolated single-use VMs on your own Claude, Codex, GLM, or Kimi credentials, verifying every change through test and review gates, and shipping merged pull requests. They are complements, not substitutes.
Keelen is an autonomous coding loop: an AI development team that runs against your GitHub repository around the clock. It turns free-form requests into a prioritized roadmap, breaks roadmap items into dev-ready tasks with acceptance criteria, implements each task in an isolated single-use VM using your own Claude, Codex, GLM, or Kimi credentials, verifies every change through test and review gates, and ships the result as a merged pull request — or holds it for your review, if that's what you've configured.

Different layers, honestly
An editor assistant makes the hours you spend coding faster. That is real leverage, and Keelen does not compete with it — Keelen has no editor, no autocomplete, no chat panel. It addresses the other twenty-odd hours: the backlog items nobody is typing on.
The two workflows never collide. An editor assistant's output lands in your working tree; Keelen's output lands as pull requests on branches, in the open, in your repository's audit history.
What a standing loop adds
You write a free-form request once. Keelen's PM layer turns it into prioritized roadmap items and dev-ready tasks with acceptance criteria, then the loop picks the top task, implements it in a fresh single-use VM, and pushes a PR — then picks the next one. Failures are classified into 30 kinds and retried on a budget; real dead ends surface as one plain-English decision card instead of silent stalls.
Verification is the point, not an afterthought. Five gates stand between the AI and your main branch. New tests are applied without the implementation first and must fail — tests born green are rejected. An independent adversarial reviewer that shares no context with the dev run reviews the diff. Your real test suite runs on a clean checkout. Nothing merges over a red required CI check. And gated auto-merge waits out a review window — or you can replace it entirely with plan-review sign-off, manual merge, or branch-only mode.
Run both
Most Keelen users keep an editor assistant for the code they write by hand and point Keelen at the roadmap they never get to. Keelen's PRs are ordinary GitHub pull requests — review them in whatever editor you already use.
FAQ
Is Keelen a replacement for GitHub Copilot?
No — they solve different problems. An editor assistant accelerates the code you are actively writing; Keelen works your backlog when nobody is typing. Many users run both: the assistant for hands-on work, Keelen for the roadmap items that never reach the top of the day.
Can I use Keelen and Copilot together?
Yes. Keelen operates at the repository level through branches and pull requests, so it coexists with any editor tooling. Its PRs are ordinary GitHub PRs you can review and edit in your own editor, assistant and all.
How does Keelen verify code with nobody watching?
Five gates stand between the AI and your main branch. New tests are applied without the implementation first and must fail — tests born green are rejected. An independent adversarial reviewer that shares no context with the dev run reviews the diff. Your real test suite runs on a clean checkout. Nothing merges over a red required CI check. And gated auto-merge waits out a review window — or you can replace it entirely with plan-review sign-off, manual merge, or branch-only mode.
Whose AI account does Keelen run on?
Keelen runs on credentials you connect: Anthropic Claude (subscription login or API key, via Claude Code), OpenAI Codex, Zhipu GLM, or Moonshot Kimi. Token usage bills to your own provider account at cost — Keelen charges a flat monthly tier ($29 / $79 / $299) and never marks up tokens.
