Which one would each critic pick
| Critic | KaibanJS | Tools4AI | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.5 | 5.3 | KaibanJS — Pick KaibanJS if watching agents move across a board is how you want to debug them; pick VoltAgent if you need MCP tools and a way to run it unattended. |
| El Crítico | 5.0 | 4.3 | 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 | 4.3 | 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 | 4.3 | no preference |
| La Jefa | 4.5 | 4.3 | KaibanJS — Free to install and pleasant in a demo, but it does not run headless, so it can never become a step in the pipeline, and support is one small repository. |
| El Hacker | 6.3 | 6.3 | no preference |
