Which one would each critic pick
| Critic | bolt.diy | v0 | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.8 | v0 — Use v0 if you ship Next.js on Vercel and want UI and full-stack scaffolding that lands in a GitHub branch, and know that training opt-out costs $100 a user and the models are Vercel's own black boxes. |
| El Crítico | 5.5 | 6.0 | v0 — v0 bills per token on composite models with no published methodology, charges $50 per million output tokens at the top tier, and sells the training opt-out as a $100-a-seat feature. |
| El Profesor | 5.3 | 5.5 | v0 — v0 asserts composite models and documents a sandbox, browser use and error fixing; the composition is undisclosed, no benchmark exists, and the Platform API is the only fully legible surface. |
| La Inversora | 4.0 | 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 | 4.5 | 6.0 | v0 — Training opt-out at $100 a user and SAML only on a custom Enterprise contract, for a tool that helps the frontend team and nobody else; approved with conditions. |
| El Hacker | 7.8 | 3.8 | 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. |
