Which one would each critic pick
| Critic | Munder Difflin | OpenRig | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 6.8 | Munder Difflin — Pick Munder Difflin if you want to orchestrate multiple terminal agents on your local machine for free, but be ready to manage the risk of them running without a sandbox. |
| El Crítico | 4.8 | 6.3 | OpenRig — OpenRig coordinates Claude Code and Codex via tmux, but the lack of an execution sandbox puts your local environment entirely at the mercy of delegating agents. |
| El Profesor | 5.8 | 4.5 | Munder Difflin — Munder Difflin is a multi-agent harness that wraps existing CLIs, but its lack of sandboxing presents a notable risk to the host system. |
| La Inversora | 7.0 | 7.0 | no preference |
| La Jefa | 4.0 | 5.0 | OpenRig — OpenRig coordinates local harnesses well, but lacks the isolation and governance sixty engineers require. |
| El Hacker | 7.5 | 6.5 | Munder Difflin — Munder Difflin is a solid MIT-licensed harness for orchestrating local agents, but the lack of a sandbox for terminal execution is a risk I'd have to manage myself. |
