Which one would each critic pick
| Critic | EvoAgentX | KaibanJS | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 5.5 | EvoAgentX — Pick EvoAgentX if you are a researcher or developer building self-improving, multi-agent systems and need a framework to automate workflow creation and evaluation. |
| El Crítico | 6.0 | 5.0 | EvoAgentX — EvoAgentX is a framework for researchers building self-evolving agent workflows, but it cannot edit multiple files or perform Git operations. |
| El Profesor | 3.8 | 5.8 | 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 | 3.5 | 4.3 | KaibanJS — About 1,470 stars since July 2024 and no commercial product behind it, which is a library rather than a company, and libraries do not raise rounds. |
| La Jefa | 4.8 | 4.5 | EvoAgentX — EvoAgentX is an open-source framework, not a managed service, and therefore lacks the enterprise features required for direct procurement. |
| El Hacker | 7.5 | 6.3 | EvoAgentX — EvoAgentX is a solid MIT-licensed framework for anyone who wants to build and iterate on multi-agent workflows with full control over the models and execution environment. |
