“It assumes your agent already works when you run it by hand, which is the most optimistic sentence in the documentation.”

Which one would each critic pick
| Critic | OpenChamber | Sortie | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.5 | Sortie — Pick this if you have a groomed backlog and an agent that already works; pick a supervised tool if either half of that sentence is aspirational. |
| El Crítico | 5.5 | 5.3 | OpenChamber — Pointing at an element sends the running page's screenshot, styles and console errors to the agent, so whatever that page contains becomes agent input. |
| El Profesor | 6.8 | 6.8 | no preference |
| La Inversora | 6.5 | 6.0 | 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 | 6.3 | Sortie — Free across sixty engineers, it runs unattended, and it tracks cost per run, which makes it one of the few things on this board I could actually put in a budget review. |
| El Hacker | 6.8 | 7.3 | Sortie — Apache-2.0 with an install script and a Homebrew cask, and it is agnostic about which agent it schedules, though there is no MCP client and no local endpoint. |
