Which one would each critic pick
| Critic | KaibanJS | MetaGPT | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.5 | 5.8 | MetaGPT — Pick MetaGPT to turn one sentence into a full document set for a greenfield idea; pick CrewAI when you want to define the roles yourself instead of inheriting a simulated company. |
| El Crítico | 5.0 | 4.8 | KaibanJS — No MCP client and no MCP server, so every tool an agent touches is bespoke integration code you write and then own forever. |
| El Profesor | 5.8 | 5.3 | KaibanJS — Agents are declared by role and goal, tasks carry an expected output, and results feed forward, with the board rendered as a view over a single state store. |
| La Inversora | 4.3 | 6.0 | MetaGPT — Seventy thousand stars against no product, no hosted service and no published pricing, which is one of the largest gaps between attention and revenue on this board. |
| La Jefa | 4.5 | 4.8 | MetaGPT — Nothing to purchase and it will run unattended, but the output is greenfield scaffolding, which is the one thing sixty engineers on a mature codebase do not need. |
| El Hacker | 6.3 | 7.3 | MetaGPT — MIT, one YAML file holds the entire configuration, and it takes any OpenAI-compatible endpoint including my own, so the whole simulated company runs on my hardware. |
