Which one would each critic pick
| Critic | Onlook | v0 | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 6.8 | Onlook — Pick Onlook if you want a visual editor that writes directly back to your Next.js and Tailwind codebase. |
| El Crítico | 7.8 | 6.0 | Onlook — Onlook bridges React code and visual DOM styling, but it binds your workflow strictly to Next.js and TailwindCSS. |
| El Profesor | 6.0 | 5.5 | Onlook — A specialized visual editor for teams standardizing UI development on Next.js and TailwindCSS. |
| La Inversora | 7.0 | 8.3 | v0 — v0 is a funnel into Vercel deploys with Next.js as the distribution, and a $30 plan that includes exactly $30 of credits tells you the subscription is the margin. |
| La Jefa | 6.5 | 6.0 | 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 | 3.8 | Onlook — A visual Next.js editor with real Apache-2.0 code, held back by closed model plumbing and zero MCP support. |
