Which one would each critic pick
| Critic | Bugbot | Mira | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.3 | Mira — Pick it if your team already ignores a review bot and you want the honest fix; pick CodeRabbit if you would rather someone else ran the service. |
| El Crítico | 6.3 | 6.5 | Mira — The learning loop synthesises rules from your merged history, so it learns what your team approved rather than what your team should have approved. |
| El Profesor | 6.0 | 7.0 | Mira — Review context is drawn from a codebase index rather than the diff alone, which is correct, and no precision or recall figure accompanies it. |
| La Inversora | 8.0 | 6.3 | Bugbot — Metered on individual plans starting at $20, this exists to move solo subscribers onto a team contract, which is the highest-value conversion in the category. |
| La Jefa | 7.0 | 7.3 | Mira — The dashboard reports cost per repository and per model, which is the number finance asks for and no review vendor has ever given me. |
| El Hacker | 3.5 | 7.8 | Mira — Apache-2.0, vulnerability scanning included in the self-hosted build, and per-provider quirks kept in config rather than code, so vLLM or Ollama is one line. |
