v0
Vercel's hosted AI agent for generating full-stack Next.js apps and live UIs from natural-language prompts, with one-click Vercel deployment, design-mode visual editing, and autonomous web search / error fixing.
Description
v0 is Vercel's hosted prompt-to-app product. It generates Next.js + Tailwind + shadcn/ui UI and backend code from natural-language prompts (or wireframes/mockups), shows a real-time live preview, and deploys to Vercel with one click. The agent plans, creates tasks, and connects to databases as it builds; it can autonomously web-search, inspect sites, fix errors, and call external tools. A design mode lets users iterate visually on generated output. Users can deploy directly or open a PR for review.
Solution
Spec-driven generation loop. User prompts (text or image); v0 plans tasks, generates code (Next.js, Tailwind, shadcn/ui), previews live, optionally inspects sites and web-searches, fixes errors automatically, and either deploys to Vercel or opens a PR. Design mode lets the user nudge the generated output through visual controls rather than text.
Primary use cases
- prompt-to-UI generation in Next.js + Tailwind + shadcn/ui
- full-stack app prototyping with real-time preview
- one-click deployment to Vercel from the agent
- visual design-mode iteration on generated code
- autonomous web search and error fixing during generation
