## How each alternative compares with CodeRabbit

- **Qodo** (Paid, $30/mo, checked 2026-11-11): Meters reviews in credits at $0.015 each pooled across up to 30 users, not per seat; the $30 pack covers 2,000 credits, and Enterprise adds on-prem and BYOK. Switch if you want pooled credits instead of per-developer seats and rules that learn from PR history. Stay with CodeRabbit if you want flat per-developer pricing with a free tier for public repositories.
- **Greptile** (Free plan + paid, $1/credit, checked 2026-11-11): No seat fees: you buy credits at $1 each, where a base review costs 1 credit, a Plus review 3 and an Apex review 10, shared across the organisation. Switch if you have many occasional contributors and prefer paying per review rather than per developer. Stay with CodeRabbit if you want a fixed per-developer price instead of credits that vary with review size.
- **GitHub Copilot** (Free plan + paid, $10/mo, checked 2026-11-11): Pull request and file-diff review is included from the $10 Pro plan and works on github.com, VS Code, JetBrains, Xcode and the GitHub CLI; reviews consume AI credits. Switch if you already pay for Copilot and want PR review bundled with it. Stay with CodeRabbit if you need GitLab support, learnings from past reviews and pre-merge quality checks.
- **Cursor (Bugbot)** (Free plan + paid, $30/mo, checked 2026-11-11): Bugbot reviews GitHub pull requests and sends fixes to the Cursor editor or Background Agent; it has no separate subscription and averages $1.00 to $1.50 per review. Switch if your team already works in Cursor and wants review findings fixed from the editor. Stay with CodeRabbit if you want a flat per-developer price and GitLab as well as GitHub.
- **Claude Code** (Paid, $20/mo, checked 2026-11-11): The /code-review command works on any plan inside a session, while managed GitHub Code Review with severity-ranked inline comments needs a Team or Enterprise plan. Switch if you want to review a branch locally in a coding-agent session on a personal plan. Stay with CodeRabbit if you want automatic reviews on every pull request without owner-level plan setup.
- **PR-Agent** (Open source, Free (self-hosted)): Community-maintained, MIT-licensed legacy project of Qodo that you run yourself as a GitHub Action, CLI or Docker image, and it can use any model through LiteLLM. Switch if you want to self-host review with your own model key and no per-seat fee. Stay with CodeRabbit if you want a hosted service with dashboards, learnings and support.
- **PR-AF** (Open source, Free (self-hosted)): Apache-2.0 reviewer built on AgentField that generates a review pipeline for each pull request, routing models through OpenRouter instead of a hosted service. Switch if you want to inspect and modify how the review pipeline is generated. Stay with CodeRabbit if you do not want to run Docker, a control plane and an OpenRouter account yourself.
- **claude-code-security-review** (Open source, Free (self-hosted)): MIT-licensed GitHub Action from Anthropic that uses Claude for semantic security review of changed files only; the README warns it should review trusted pull requests only. Switch if you only need a security-focused review action billed to your own Claude API key. Stay with CodeRabbit if you need general bug and quality review, summaries and handling of untrusted external contributors.

The documented reasons are: CodeRabbit added a usage-based add-on that bills reviews pay-per-use once a plan's review limit is reached, so heavy teams can pay beyond their seat price (9 Apr 2026); Each plan carries a per-developer hourly review allowance (Essentials 5, Team 8, Advanced 10), lowered to 1 per hour after heavy recent use (11 Nov 2026). Each is sourced in the section above.

It depends on the job. Qodo suits pooled credits and team rules, Greptile suits per-review pricing, and Copilot suits teams already paying for it. None is ranked above CodeRabbit on every point.
