Which one would each critic pick
| Critic | cmux | Hermes Studio | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.5 | Hermes Studio — Pick Hermes Studio if you want a free, open-source workbench to run and compare multiple local agents without touching the command line. |
| El Crítico | 6.5 | 5.5 | cmux — A programmable browser lives inside the same application that hosts your agents and your remote sessions, and no sandbox is recorded anywhere on the row. |
| El Profesor | 6.8 | 4.0 | cmux — Attention routing is built on OSC 9, 99 and 777 escape sequences rather than a private hook, which is the design choice most likely to outlast the agents it hosts. |
| La Inversora | 6.0 | 7.0 | Hermes Studio — This is a free, open-source aggregator with respectable adoption but no visible business model, making its long-term maintenance and survival questionable. |
| La Jefa | 5.5 | 5.5 | no preference |
| El Hacker | 7.5 | 8.8 | Hermes Studio — Hermes Studio is a proper MIT-licensed orchestrator for multiple agents, giving you a local runtime with full MCP support and model freedom. |
