Which one would each critic pick
| Critic | bolt.diy | Onlook | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 7.3 | Onlook — Pick Onlook if you want a visual editor that writes directly back to your Next.js and Tailwind codebase. |
| El Crítico | 5.5 | 7.8 | Onlook — Onlook bridges React code and visual DOM styling, but it binds your workflow strictly to Next.js and TailwindCSS. |
| El Profesor | 5.3 | 6.0 | Onlook — A specialized visual editor for teams standardizing UI development on Next.js and TailwindCSS. |
| La Inversora | 4.0 | 7.0 | Onlook — Treat Onlook as an open-source visual prototyping experiment while monitoring how the team monetizes its upcoming hosted tier. |
| La Jefa | 4.5 | 6.5 | Onlook — Open-source visual editor for Next.js, but lacks the audit logs, SSO, and centralized controls required for team adoption. Not yet. |
| 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. |
