Which one would each critic pick
| Critic | CC GUI | Nimbalyst | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.5 | Nimbalyst — Pick it if you want to read every agent change before it lands; pick Proliferate if you would rather the agents just run and you check the branch later. |
| El Crítico | 6.3 | 6.5 | Nimbalyst — Two of the five advertised agent providers, OpenCode and GitHub Copilot, are documented as alpha, so the roster on the front page is larger than the one you can rely on. |
| El Profesor | 7.5 | 7.0 | CC GUI — The listing documents its own network path: requests go direct to the official API unless a proxy is set, the route is labelled first, and no credential is read without a dialog. |
| La Inversora | 7.3 | 6.5 | CC GUI — 5,809 stars in under a year, MIT, no meter and no seat, published by CodeMoss AI. The asset is marketplace attention, and attention is convertible if the vendor wants it to be. |
| La Jefa | 5.3 | 6.3 | Nimbalyst — No licence cost at sixty seats, but nothing runs unattended, and the iOS companion means diff approval leaves the laptop for a device we do not manage. |
| El Hacker | 8.0 | 7.8 | CC GUI — MIT with a gradlew buildPlugin target, so the fork path is a clone away, and MCP servers attach to the panel rather than to whichever CLI happens to be running. |
