Which one would each critic pick
| Critic | Codeg | OpenChamber | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.3 | Codeg — Pick Codeg if you keep switching between coding CLIs and losing your place; pick Vibe Kanban when parallel task management matters more than session continuity. |
| El Crítico | 5.8 | 5.5 | Codeg — It imports the session history of fifteen coding CLIs, which means depending on fifteen private on-disk formats that their owners can change without notice. |
| El Profesor | 6.0 | 6.8 | OpenChamber — A goal is checked after every turn and the loop continues until it is met, blocked, or a limit is reached, which is a stated termination condition. |
| La Inversora | 6.0 | 6.5 | OpenChamber — 9,556 stars and over twenty-three thousand editor installations from a repository that did not exist before September 2025, with nothing charged for any of it. |
| La Jefa | 6.0 | 6.0 | no preference |
| El Hacker | 7.5 | 6.8 | Codeg — Apache-2.0, a single docker run, MCP servers and skills supported, and any agent speaking ACP can be registered rather than waiting for built-in support. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
