“It gives you push, pull, clone and snapshot for agents, so you can now have a merge conflict with a colleague you invented.”

“There is a public instance at app.warren.run, which is a generous offer from someone who knows exactly what agents cost to run.”

| Browser control | No | No |
| Sandboxed execution | YesAgents can be placed in Docker containers, on Modal or on remote hosts, with SSH key isolation, network allowlists and full container control. | YesEach run stays inside a sandbox boundary chosen per deployment; watchdogs reconcile lost processes and pods, implying container or pod backends. |

Which one would each critic pick
| Critic | mngr | Warren | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.5 | no preference |
| El Crítico | 6.8 | 6.8 | no preference |
| El Profesor | 6.8 | 7.3 | Warren — The guaranteed output of a run is a pushed branch, with pull requests and tracker updates layered on top, so success is defined as an artefact rather than as a transcript. |
| La Inversora | 6.5 | 5.8 | mngr — 410 stars, and the public repository is an automatic mirror of an internal one: the roadmap is decided somewhere you cannot see, by a lab with other priorities. |
| La Jefa | 7.0 | 6.3 | mngr — Key isolation per agent, network allowlists and full container control across sixty engineers, and the cost is compute rather than seats, which is a line I already forecast. |
| El Hacker | 8.0 | 7.5 | mngr — MIT, plugins to extend it, and the same commands drive Claude Code, Codex or OpenCode, so the harness stops being a thing I choose once and then live with forever. |
