Which one would each critic pick
| Critic | Code Puppy | OpenDev | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 7.0 | OpenDev — Pick it if you want a terminal agent that is one binary and nothing else; pick a heavier tool if you need it to manage branches for you. |
| El Crítico | 6.0 | 6.3 | OpenDev — It spawns parallel agents into one project, records no git operations and describes no isolation, so concurrent writes are a question the row does not answer. |
| El Profesor | 7.0 | 6.5 | Code Puppy — Tool calls go through Pydantic AI, so arguments are validated by a typed library rather than recovered from prose, which removes a whole error class. |
| La Inversora | 6.5 | 6.5 | no preference |
| La Jefa | 6.0 | 5.3 | Code Puppy — It states that it makes no calls beyond the provider you configure, which is a claim I like and not a policy I can hold anyone to. |
| El Hacker | 7.5 | 8.0 | OpenDev — MIT, `cargo install`, MCP servers attach, and Ollama or LM Studio are in the provider list, so a worker can run on weights I serve myself. |
