“It writes Lua to get work done in Elixir, which is two functional languages agreeing that a third one should take the blame.”

Which one would each critic pick
| Critic | Legion | PageAgent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.5 | Legion — Pick Legion if you write Elixir and want the agent inside the application rather than beside it; pick a framework in Python if the rest of your stack already lives there. |
| El Crítico | 6.0 | 5.8 | Legion — The generated snippet runs in the project's own sandbox, and the README does not describe a container runtime, so the isolation boundary is whatever the host process could already reach. |
| El Profesor | 7.8 | 6.8 | Legion — One evaluation can filter, branch and loop, so a sequence that costs a tool-calling agent a model round trip per step collapses into a single call. The claim is structural and checkable. |
| La Inversora | 6.3 | 6.0 | Legion — 166 stars and a consultancy's name on it. Software Mansion builds open libraries to sell engineering time, which funds this exactly as long as the pitch still works. |
| La Jefa | 5.5 | 6.0 | PageAgent — This is a dependency review, not a purchase: nothing is billed, but every end user we ship it to generates model calls on an endpoint we are paying for. |
| El Hacker | 6.8 | 8.0 | PageAgent — MIT, npm install page-agent, any OpenAI-compatible endpoint including a locally deployed model, and it runs an MCP server so my own clients can drive the page. |
