“It is built to be run by your coding agent rather than by you, which is the first tool here honest about who its actual user is.”

Which one would each critic pick
| Critic | OpenReview | revmux | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.8 | 6.0 | revmux — Pick it when the thing you want reviewed is a plan or a proposal rather than code; pick a normal review bot when it is a pull request and nothing else. |
| El Crítico | 5.3 | 5.5 | revmux — It performs no scope detection and fetches nothing itself, so the review is entirely a function of the context whoever called it happened to write to disk. |
| El Profesor | 7.0 | 6.3 | OpenReview — The review executes linters, formatters and the test suite inside the environment rather than reasoning about them, which is the only honest form of verification here. |
| La Inversora | 5.3 | 5.0 | OpenReview — This is a labs release, not a product: no hosted tier, no price, and the commercial logic is that every review burns the parent's platform compute. |
| La Jefa | 5.3 | 5.0 | OpenReview — There is no seat price because there is no product: sixty developers costs whatever the sandbox compute and the model tokens come to, which is two meters and no cap. |
| El Hacker | 5.8 | 6.0 | revmux — MIT and a Go binary that writes to standard output and modifies nothing, which is the most unix thing anyone has shipped in this category. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
