Which one would each critic pick
| Critic | Onlook | Cloudflare VibeSDK | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.0 | Onlook — Pick Onlook if you want a visual editor that writes directly back to your Next.js and Tailwind codebase. |
| El Crítico | 7.8 | 6.5 | Onlook — Onlook bridges React code and visual DOM styling, but it binds your workflow strictly to Next.js and TailwindCSS. |
| El Profesor | 6.0 | 7.0 | Cloudflare VibeSDK — The loop is model-and-tool rather than a fixed sequence of generation phases, and verification closes on the deployed preview's own console output rather than on a separate test run. |
| La Inversora | 7.0 | 7.5 | Cloudflare VibeSDK — Cloudflare publishes the platform because every generated application consumes its compute, storage and gateway, so the open source is the sales motion, not a side project. |
| La Jefa | 6.5 | 6.3 | 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 | 7.3 | 6.5 | Onlook — A visual Next.js editor with real Apache-2.0 code, held back by closed model plumbing and zero MCP support. |
