Which one would each critic pick
| Critic | bolt.diy | Doop | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.8 | Doop — Doop is an excellent open-source canvas for collaborative UI brainstorming with AI, but it is not a production design tool. |
| El Crítico | 5.5 | 6.3 | Doop — Doop's AGPL-3.0 license is a dealbreaker for most commercial use cases, restricting its multiplayer design canvas to open-source projects or internal tools. |
| El Profesor | 5.3 | 5.5 | Doop — Doop's multiplayer canvas and MCP server provide a structured environment for UI generation, though its utility is confined to HTML rendering within iframes. |
| La Inversora | 4.0 | 4.5 | Doop — A clever open-source play for mindshare in the AI-native design space, but its business model is a question mark without a clear path to revenue. |
| La Jefa | 4.5 | 3.8 | bolt.diy — Nothing to procure: no seats, no SSO, no audit log, no retention policy, no headless mode, and sixty engineers each running an Electron app or a dev server on a laptop. |
| El Hacker | 7.8 | 7.3 | bolt.diy — MIT, keys in .env.local, nineteen providers including Ollama and LM Studio for a fully local run, MCP servers, and docker compose --profile development; this is the Bolt I would run. |
