Which one would each critic pick
| Critic | Emergent | Cloudflare VibeSDK | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.8 | 7.0 | Cloudflare VibeSDK — Pick VibeSDK if you want an app builder running in an account you control; pick Lovable if you would rather nobody asked you to own any of the infrastructure. |
| El Crítico | 5.3 | 6.5 | Cloudflare VibeSDK — Every structural piece is a product from one vendor, so the open licence buys you the source and not portability: self-hosting means hosting it in their account. |
| El Profesor | 5.3 | 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 | 6.0 | 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 | 4.5 | 6.3 | Cloudflare VibeSDK — It produces applications rather than reviewable changes, so it belongs to prototyping and never to the pipeline sixty engineers ship through. |
| El Hacker | 4.0 | 6.5 | Cloudflare VibeSDK — MIT, the entire platform deploys into my own account from one button, the gateway lets me choose the provider, and project export gets the code out again. |
