Which one would each critic pick
| Critic | UniHarness | VibeAround | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.5 | VibeAround — Pick VibeAround if you have collected half a dozen agent CLIs and are tired of editing all their config files; pick one agent and stay there if you have not. |
| El Crítico | 5.8 | 5.8 | no preference |
| El Profesor | 7.3 | 6.8 | UniHarness — A protocol separates the runtime from the machine it drives, and the runtime's keys, configuration and source are kept outside what the agent can read. |
| La Inversora | 5.3 | 5.8 | VibeAround — 525 stars and a permissive licence on a launcher for ten other companies' agents: every one of them captures the value, and this captures the configuration burden. |
| La Jefa | 5.3 | 5.0 | UniHarness — Free across sixty engineers and able to run unattended, but the confined remote target is a third-party service, which is a supplier my security review has to process. |
| El Hacker | 6.8 | 7.0 | VibeAround — MIT, and it refreshes a reserved MCP entry inside each launched agent's own configuration so that agent can reach the host-side tools this thing exposes. That is a neat trick. |
