v0

v0 is Vercel's AI agent for building software from natural language descriptions. Originally launched in late 2023 as a tool for generating individual React components from text or image prompts, it has grown into a full-stack app builder that can scaffold Next.js applications complete with API routes, server actions, and database connections to services like Supabase and Snowflake. Users describe what they want to build, and v0 generates a working UI along with the backend logic to support it, offering live previews, automatic error fixing, and one-click deployment through Vercel's own infrastructure. A Git panel and VS Code-style editor let developers refine the generated code directly, and agentic workflows allow v0 to carry out multi-step changes rather than just producing a single response. Vercel positions v0 for a wide range of roles beyond engineers, including product managers prototyping ideas, designers implementing UI changes without writing code, and founders building MVPs. Because v0 is tightly coupled to Vercel's deployment platform and its preferred stack of Next.js, Tailwind, and shadcn/ui, teams committed to a different hosting provider or framework may find it less useful than teams already building on Vercel.
