At a glance
| Capability | ReviewGate | GitHub Copilot code review |
|---|---|---|
| Deployment / data residency | Self-hosted CLI; diffs go only to the LLM endpoint you configure | Hosted by GitHub; code processed on GitHub's infrastructure |
| LLM provider choice | Any OpenAI-compatible or Anthropic endpoint (DeepSeek, Kimi, GLM, Qwen, Claude, …) | GitHub-managed models; no bring-your-own endpoint |
| Output form | A verdict: BLOCK / WARN / pass, with exit codes 0 / 1 / 2 for CI | Review comments and suggestions on the PR |
| Gate semantics | Designed as a merge gate; --fail-on block|warn fails the pipeline |
Advisory by default; gating requires wiring branch-protection rules around it |
| Incomplete review handling | Timeout / oversized context degrade to WARN + non-zero exit; never a fake PASS | No explicit incomplete-review contract |
| Findings validation | Line anchoring, cross-dimension dedup, counter-evidence judge | Model-side filtering; internals not public |
| Works outside GitHub | Any git repo — GitLab, Gitea, local, air-gapped CI | GitHub only |
| Pricing model | MIT open source; you pay only your own LLM usage | Part of Copilot subscription plans |
| Public evaluation logs | Raw benchmark runs committed under docs/evals/ | Not public |
When Copilot code review is the better fit
- Your team already pays for Copilot and lives entirely inside GitHub PRs.
- You want zero setup: no binary, no CI step, no API key management.
- You mainly want inline suggestions and conversational review, not a hard gate.
- Your org is fine with code being processed by GitHub's managed models.
When ReviewGate is the better fit
- Code cannot leave your infrastructure, or you must pick the exact LLM endpoint (including domestic providers like DeepSeek, Kimi, GLM, Qwen).
- You need a real merge gate in CI: exit 0 clean, exit 1 blocked, exit 2 tool failure — not just comments someone may ignore.
- You review AI-generated changes in bulk and care about "never fake a PASS" semantics when the review times out or the diff is oversized.
- You are not on GitHub, or you also review local diffs before pushing.
Can you use both?
Yes, and it is a reasonable setup: Copilot code review for conversational, in-PR feedback, and ReviewGate as the last pre-merge gate in CI that decides whether the pipeline goes red. They do not conflict — one produces comments, the other produces a verdict.
Try ReviewGate on your next PR
Install the CLI in one command, point it at your LLM endpoint, and run reviewgate review --fail-on block in CI.
