Which one would each critic pick
| Critic | Mira | Seer | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.0 | 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 | 6.5 | 6.5 | no preference |
| El Profesor | 7.0 | 6.8 | 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 | 6.3 | 7.8 | Seer — Selling this as an add-on to an existing subscription is the cheapest distribution in the category: the data moat was already paid for by the monitoring product. |
| La Jefa | 7.3 | 6.8 | 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 | 7.8 | 4.3 | 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. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
