Which one would each critic pick
| Critic | Cheshire Cat AI | PI from Scratch | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.3 | 4.3 | Cheshire Cat AI — Pick Cheshire Cat if you are learning how agent runtimes fit together; pick Flowise when you want to assemble something usable this afternoon. |
| El Crítico | 5.0 | 5.0 | no preference |
| El Profesor | 5.5 | 3.3 | 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 | 5.3 | 6.5 | PI from Scratch — This is a well-executed open-source tutorial, not a company; it's a portfolio piece for its creator, not a foundation for a business. |
| La Jefa | 4.5 | 3.3 | Cheshire Cat AI — Nothing per seat, and a strong copyleft licence plus an alpha label means two separate reviews before sixty developers could touch it. |
| El Hacker | 6.8 | 8.0 | PI from Scratch — PI from Scratch is an MIT-licensed tutorial, not a production tool, but it's the right way to learn how an agent works from the metal up. |
