Which one would each critic pick
| Critic | LightAgent | uAgents | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.3 | LightAgent — Pick this if you are a Python developer who wants a free, open-source framework to build multi-agent systems and can handle sandboxing yourself. |
| El Crítico | 5.3 | 5.5 | uAgents — Each agent registers on a smart contract on the Fetch.ai blockchain at startup, so a local process now depends on an external network before it is doing anything useful. |
| El Profesor | 4.0 | 6.5 | uAgents — Identity is derived deterministically from a seed and messages between agents are signed, so the sender of a message is verified rather than asserted in its payload. |
| La Inversora | 5.8 | 5.8 | no preference |
| La Jefa | 5.3 | 5.5 | uAgents — Nothing to license for sixty engineers and nothing to administer, and the supported Python range stops at 3.13, which becomes my problem on the next platform upgrade. |
| El Hacker | 8.0 | 6.8 | LightAgent — LightAgent is a solid Python framework for building agents you can actually own, with great model freedom and a permissive license. |
