Postil vs Greptile
Greptile's cross-file reasoning is genuinely strong. Postil is a Greptile alternative for teams who hit the limits of its commercial model and merge contract: per-review overage pricing gets punishing at agent-team volume, and findings ship as comments rather than a separable, enforceable gate.
| Capability | Postil | Greptile |
|---|---|---|
| Hard merge gate (separate blocking check) |  Yes. postil/gate, fail-closed |  No. comments only |
| Published silence / quiet-rate metric | Yes. headline dashboard number | no |
| Pricing | Flat $10/dev, BYO key, zero markup | ~$30/seat + ~$1 per review past 50 |
| Cost at high PR volume | Yes. flat — seats × $10 | No. scales with review count |
| Self-host without enterprise sales | Yes. free, Docker Compose | no |
| Platforms | Hosted app: GitHub. CLI/CI: GitHub, GitLab, Bitbucket + Azure DevOps (early) | GitHub, GitLab |

Per-review pricing breaks at agent speed
Greptile's March 2026 move to $30/seat plus $1 per review past 50 produced a public backlash. A developer pushing several hundred agent-driven PRs in a month can owe hundreds of dollars. Postil charges a flat $10 per developer per month and routes inference through your own key at provider rates with zero markup, so your worst-case bill is seats times ten — independent of PR count. Compare on the cost calculator.
A gate you can require, not just comments to read
Greptile posts findings as PR comments. Postil completes postil/gate as a real, separable check you can require in branch protection, distinct from advisory postil/review commentary. On operational errors the gate fails closed by default rather than completing neutral; repos can opt into gate.onError: advisory, which fails open on provider outages only.
Restraint is measured
Greptile's own v4 release notes show comments-addressed rising from 30% to 43% between versions — evidence that defaults trend noisy. Postil reports its silence rate and the confidence distribution of shipped findings as the headline metrics, so drift toward noise is visible in a chart before engineers feel it in notifications.
Where Greptile is ahead
Greptile's cross-file recall on large codebases is a real strength, and it has a longer track record on deep repository context. Postil optimizes the precision of what it says over breadth of recall.
