Which one would each critic pick
| Critic | Async IDE | ThinkRail | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 7.3 | ThinkRail — Pick it when you want a task to have its own branch, files and terminal without thinking about it; pick your usual IDE if one task at a time is enough. |
| El Crítico | 6.0 | 6.5 | ThinkRail — It hosts another project's agent in-process, and that project owns models, compaction, cost and session state, so the parts users complain about are not fixable here. |
| El Profesor | 7.0 | 6.8 | Async IDE — The control loop is named and exposed: Think, Plan, Execute, Observe, with each stage visible and interruptible rather than collapsed into one opaque completion. |
| La Inversora | 5.8 | 6.0 | ThinkRail — 412 stars and a large vendor calling it an incubator project, which is the clearest expiry signal any company on this board has volunteered. |
| La Jefa | 5.3 | 6.5 | ThinkRail — A signed installer from a company legal has already contracted with is the easiest security review here; there is still no SSO, no audit log and nothing in CI. |
| El Hacker | 7.8 | 7.0 | Async IDE — Apache-2.0, Ollama and vLLM named directly rather than implied, MCP servers attach, and each agent carries its own model, workspace and allowlist. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
