v0 produces production Next.js + Tailwind + shadcn UI components. Bolt runs full-stack apps live in a browser WebContainer. Pick v0 for UI inside a Next.js codebase, Bolt for full-app prototyping.

## At a glance

| Dimension | v0 (Vercel) | Bolt (StackBlitz) |
|---|---|---|
| Output type | UI components + pages | Full-stack app running live |
| Stack | Next.js + Tailwind + shadcn (fixed) | **Next.js / Vite / SvelteKit (pick)** ✓ |
| Execution | Code-only — you deploy | **Live in WebContainer — runs immediately** ✓ |
| UI quality (first try) | **State of the art (shadcn)** ✓ | Solid |
| Backend / DB / auth | No | **Limited but possible in WebContainer** ✓ |
| Iteration speed | Fast | **Faster — no deploy step** ✓ |
| Code export to GitHub | Yes | Yes |
| Best for | UI inside an existing Next.js app | Full-app prototyping + exploration |

## Verdict

v0 wins when you need production-quality UI components inside an existing Next.js codebase — its shadcn defaults are unmatched. Bolt wins for full-app prototyping where you want the app running live in a browser and you value stack flexibility over UI polish. Many builders use both: Bolt for the v0.1, then v0 to upgrade specific UI sections after export to a Next.js codebase.

## When to pick which

- **v0 (Vercel)** — Next.js project, production UI components, design-system polish.
- **Bolt (StackBlitz)** — Full-app prototyping, stack flexibility, in-browser iteration.
