Which one would each critic pick
| Critic | CodeRabbit | cubic | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.8 | 7.0 | 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 | 6.5 | no preference |
| El Profesor | 6.5 | 6.5 | no preference |
| La Inversora | 7.8 | 6.3 | 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 | 4.0 | CodeRabbit — Cloud-only and closed, so I cannot read the reviewer or run it on my box, but the CLI, MCP client and BYOK give me more handles than most closed review bots do. |
