Footnotes
- Codex — the Codex CLI is open source; the hosted Codex product is closed.
- Claude Code — the
anthropics/claude-code-actionGitHub Action is open source; the Claude Code CLI/platform is a commercial Anthropic product. - Qodo — the PR-Agent core is AGPL-3.0 and supports OpenAI GPT, Claude, DeepSeek, and more. The hosted Qodo Merge product is a closed commercial layer on top.
- Greptile — OSS and startup discounts are available but not a free tier. (greptile.com/pricing)
- Codex — “Codex for Open Source” program offers free API credits and ChatGPT Pro access by application.
- Qodo — Developer tier is $0/month with 30 free PRs/month promo and 75 credits. (qodo.ai/pricing)
- CodeRabbit — self-host is available only to Enterprise customers with 500+ seats; on the self-hosted build, customers plug in OpenAI, Azure OpenAI, AWS Bedrock, or Anthropic directly. (docs.coderabbit.ai/self-hosted/github)
- Greptile — self-hosting in AWS is available only on the Enterprise plan, which also unlocks BYO LLM. (greptile.com/pricing)
- Claude Code — reviews run on GitHub-hosted runners via the Action; the Claude Code CLI itself runs locally. No “self-hosted control plane” in the MergeWatch sense.
- Claude Code — built as a single-agent loop with tool use and a configurable
--max-turns; not a pre-built multi-agent review pipeline. - CodeRabbit / Cursor BugBot — 14-day free Pro trials rather than a free tier.
- Codex — bundled with ChatGPT Plus/Pro/Business/Edu/Enterprise plans; API access is pay-as-you-go at standard OpenAI rates.
- Greptile — Cloud is 1 per additional review.
- Copilot code review — non-licensed org members access it through “premium requests” that bill separately.
- Claude Code — Action runs cost GitHub Actions minutes + Anthropic API tokens; subscription plans are per-seat.
- Qodo Teams — $30/user/month annual with 2,500 credits/user/month.
How to use this matrix
- If self-hosting is a requirement, only MergeWatch and Qodo offer it without seat gates; CodeRabbit and Greptile have enterprise-only paths.
- If you need local/air-gapped inference, MergeWatch (via Ollama) and Qodo (via on-prem/air-gapped deployments) are the only options listed.
- If you want a fully open-source review pipeline you can audit line-by-line, only MergeWatch offers this under AGPL-3.0 across the full pipeline (Qodo’s PR-Agent is AGPL but the hosted product is closed).
- If you already pay for Copilot, ChatGPT, or Claude, the bundled review features are the cheapest marginal cost — but you lose multi-model choice and most have no self-host option.
