Postil vs CodeRabbit
CodeRabbit is the most widely deployed AI reviewer and has the broadest platform coverage. Postil is a CodeRabbit alternative built around restraint and structure: a hard merge gate separate from advisory comments, a published silence rate, and pricing based on active private-PR authors rather than repositories.
| Capability | Postil | CodeRabbit |
|---|---|---|
| Dedicated fail-closed merge gate |  Yes. postil/gate, fail-closed |  Partial. built-in checks; custom checks on Pro Plus |
| Published silence / quiet-rate metric | Yes. headline dashboard number |  no |
| Pricing | Per active private-PR author; 30-day hosted trial | ~$24/seat (Pro, annual) |
| Self-host without enterprise sales | Yes. free, Docker Compose | Partial. enterprise-gated |
| Platforms | GitHub App: GitHub. CLI/CI: GitHub, GitLab, Bitbucket + Azure DevOps on a best-effort CI gate | GitHub, GitLab, Azure DevOps, Bitbucket |
| Config compatibility | Yes. reads .coderabbit.yaml | Yes. native |

The merge gate is the difference that matters
CodeRabbit's pricing page lists built-in pre-merge checks on Pro and custom pre-merge checks on Pro Plus, so it is not a comments-only tool. The difference is structure. Postil ships a dedicated gate:postil/gate fails only at or above your configured severity and is safe to require in branch protection, while postil/review carries advisory findings. On operational errors the gate fails closed by default; repos can opt into gate.onError: advisory, which fails open on provider outages only.
CodeRabbit's noise rate, measured directly
An independent audit of 28 CodeRabbit-reviewed PRs rated 15% of its comments useless and another 21% nitpicking. Postil ships with a high confidence threshold by default and reports its silence rate (the share of PRs where it said nothing) as the first number on the dashboard, with the confidence distribution of every finding it did ship.
Postil bills active private-PR authors
CodeRabbit Pro is $24 per seat per month on the annual plan. Postil prices private plans by active author. BYOK provider usage is billed directly. Hosted starts with a 30-day trial. See the pricing details.
Where CodeRabbit is ahead
CodeRabbit's Azure DevOps and Bitbucket support is mature and widely deployed. Postil's CLI supports both behind the same forge abstraction that covers GitHub and GitLab on a best-effort basis, and Postil's hosted app is GitHub-only. If your install finds a platform-specific edge case, we want the report.
Keep your .coderabbit.yaml.
Postil reads it. Install the App for a hosted trial, connect BYOK, or install the CLI and review your next diff.
