Compare Postil with other AI reviewers.

An independent audit of 28 CodeRabbit-reviewed PRs rated 15% of its comments useless noise and another 21% nitpicking. Greptile's own v4 release notes show comments-addressed rising from 30% to 43% between versions, evidence that defaults in this category trend noisy.

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 your dashboard, with the confidence distribution of every finding it did ship. GitHub reports that Copilot code review stays silent on roughly 29% of reviews, but the number lives in a blog post, not on your dashboard; we make it the headline.

CodeRabbit Pro is $24 per seat per month on the annual plan. Greptile's March 2026 move to $30/seat plus $1 per review past 50 produced a public backlash site; a developer pushing 571 agent-driven PRs in 30 days would owe roughly $500 a month. GitHub moved Copilot code review onto Actions-minutes billing in June 2026; the community discussion of the underlying usage-based billing change ran 958 downvotes to 24 upvotes, with one developer reporting 8% of a monthly allotment burned in two hours.

Postil prices private plans by active author. BYOK provider usage is billed directly. Hosted starts with a 30-day trial. A comparable model is Kodus, at $10 per developer plus passthrough, with minimal distribution.

Several reviewers we compare put blocking-severity and style-level findings into the same review stream. GitHub Copilot's review completes as a neutral grey check that reads as "didn't fail". Teams that want "block on critical, ignore nits" build it by hand from raw check statuses.

Postil completes two named check-runs on every non-draft PR in an enabled repository: postil/gate fails only at or above your configured severity and is safe to require in branch protection; postil/review carries everything advisory. On operational errors the gate fails closed by default, never neutral. Repos can opt into gate.onError: advisory, which fails open on provider outages only.

Many of the highest-precision review tools are GitHub-only. Teams on GitLab Self-Managed in regulated industries are left choosing between platform support and review quality.

Postil's CLI speaks GitHub, GitLab, Bitbucket, and Azure DevOps (each including its self-managed/server variant via a base-URL environment variable) through the same forge interface. Bitbucket and Azure DevOps support follows the same best-effort contract: shipped, covered by tests, and driven by customer feedback where platform edge cases differ. The CLI's interactive @postil bot (postil respond) follows the same reach: GitHub and GitLab cover issues and PRs/MRs, Bitbucket and Azure DevOps cover pull requests only. The hosted app supports GitHub only. Off GitHub the gate is enforced as a CI job that passes or fails, rather than a named external check-run like GitHub's postil/gate.

PR-Agent's self-hosted config silently fell back to OpenAI when pointed at non-OpenAI models, and a v0.33 regression overwrote non-OpenAI API keys with dummy values. Bito charges a $5/seat add-on for self-hosting. CodeRabbit gates it behind enterprise sales.

Postil ships a Docker Compose that brings up Postgres, the web app, and the worker, validates every required setting at startup with an actionable error message, and documents working configs for OpenRouter, Azure OpenAI, and local Ollama. postil doctor verifies your endpoint, key, and model before the first review. The stack is Apache-2.0 with no seat fees or license cost; you supply inference and infrastructure.

Most tools re-review the whole PR on every push, so a one-line fixup triggers a fresh flood. Cursor BugBot shipped incremental review in June 2026; few others have it.

Postil records the envelope of every completed review. On the next push it reviews only what changed since the last reviewed commit, reconciles prior findings, and reports "N resolved, M open" instead of repeating itself. The control plane passes the previous envelope to the CLI automatically.

None of the reviewers on our comparison pages documents a replay that shows what a config change would have done before deployment. Teams otherwise tune review settings against live PRs.

postil plan re-applies a candidate config to your stored envelopes (no model calls, no API spend) and shows exactly which findings would have shipped, been suppressed, or failed the gate on your recent PRs. Terraform-plan semantics for review configuration.
