“It runs its admin interface on port 1865, and the Italian name is Stregatto, so the branding got more attention than the release notes.”

Which one would each critic pick
| Critic | ChatDev | Cheshire Cat AI | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.8 | 5.3 | ChatDev — Pick ChatDev to watch role-playing agents build a small program from nothing; pick OpenHands the moment the code already exists and has users. |
| El Crítico | 5.8 | 5.0 | ChatDev — Version 2.0 turned a research project into a zero-code console and pushed the classic line to a legacy branch, so the version every paper describes is now the old one. |
| El Profesor | 4.8 | 5.5 | Cheshire Cat AI — The design puts the agent behind a REST boundary with an interactive schema, which makes the runtime an inspectable service rather than a library call. |
| La Inversora | 5.5 | 5.3 | ChatDev — OpenBMB is a research organisation, and 34,000 stars of academic distribution is influence with no invoice attached anywhere in it. |
| La Jefa | 4.8 | 4.5 | ChatDev — Nothing to buy and nothing that runs unattended, so it cannot be scheduled, measured or supported, which leaves it as an experiment on somebody's laptop. |
| El Hacker | 5.8 | 6.8 | Cheshire Cat AI — GPL-3, which means my fork stays open and so does everybody else's, one uv command to run it, and Python plugins that add tools and hooks. |
