Which one would each critic pick
| Critic | amux | Supacode | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.0 | amux — Pick amux if you want a fleet of agents working overnight with a board to wake up to; pick Crystal if you would rather supervise a couple of them yourself. |
| El Crítico | 5.5 | 5.5 | no preference |
| El Profesor | 6.3 | 6.8 | Supacode — Sessions run inside a separate session daemon rather than as children of the application, so the interface is a viewer over state that outlives it. |
| La Inversora | 5.0 | 4.8 | amux — MIT with a Commons Clause bolted on is not open source, and 383 stars from a vendor whose real product is elsewhere makes this a side project with a moat clause. |
| La Jefa | 5.0 | 4.0 | amux — There is no licence fee and no right to resell it either, and no CI integration is documented, so it schedules its own work outside anything I already monitor. |
| El Hacker | 6.5 | 4.8 | amux — One Rust binary with a SQLite store, model or provider swappable mid-run without losing context, and Ollama listed among the worker runtimes. |
