Which one would each critic pick
| Critic | CodeRabbit | Open Code Review | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.8 | 6.8 | CodeRabbit — CodeRabbit is the PR reviewer I would install today, free on public repos and with a pre-commit CLI that plugs into your coding agent, as long as you treat its comments as a second opinion. |
| El Crítico | 6.5 | 6.0 | CodeRabbit — By the number CodeRabbit itself reports, precision on Code Review Bench is 49.2%, so on that benchmark roughly one comment in two is not a real finding. |
| El Profesor | 6.5 | 6.8 | Open Code Review — The reported figures come from a self-authored 200-pull-request benchmark claiming higher precision at roughly a ninth of the tokens, with no methodology published to check either number. |
| La Inversora | 7.8 | 6.8 | CodeRabbit — Free for public repos is a distribution engine, the $24 to $72 seat ladder is pricing power, and both Git hosts it lives on would rather own it than compete with it. |
| La Jefa | 7.0 | 6.0 | CodeRabbit — Sixty seats on Team is $2,880 a month, it runs on all four Git hosts we could plausibly use, and Enterprise self-hosting exists, so this is a procurement I can actually finish. |
| El Hacker | 4.3 | 8.0 | Open Code Review — Apache-2.0, a global npm install, and an MCP client, so I can bolt my own servers onto the review and read every rule that produced a comment. |
