Which one would each critic pick
| Critic | Codel | Terragon | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 3.8 | 3.3 | Codel — Do not adopt: this stopped receiving commits in 2024, and anyone who wants a self-hosted agent with a shell and a browser should be running OpenHands. |
| El Crítico | 3.8 | 3.3 | Codel — No commits since 2024, and for a project whose runtime is a container image and a model API, standing still means decaying against two moving dependencies at once. |
| El Profesor | 4.3 | 5.0 | Terragon — The design routed all agent output through pull requests, so verification borrowed the organisation's existing review process rather than inventing one. |
| La Inversora | 3.5 | 3.0 | Codel — A single developer's project with no entity behind it, from the wave of 2024 clones that the model vendors made redundant by shipping their own harnesses. |
| La Jefa | 3.0 | 2.8 | Codel — Self-hosting an unmaintained service that spawns containers and holds a provider key is a security finding with a web interface, and there is nobody to escalate to. |
| El Hacker | 5.5 | 5.0 | Codel — AGPL-3.0, one docker run with OPEN_AI_KEY and port 3000, and Ollama support, so the whole thing runs on my hardware with nothing phoning home. |
