v0

v0 is Vercel's AI app builder. It started as a generator for React and Tailwind CSS UI components and has grown into a builder for full Next.js applications, created from natural-language prompts, screenshots, or design files. Output uses shadcn/ui as its default component library, so the code follows the same conventions many Next.js teams already use.

The workflow is conversational: describe what you want, check the live preview, and refine through follow-up messages. Design Mode then lets you click any element in the preview to move, resize, or restyle it without another prompt. v0 can wire in databases, authentication, and APIs through Vercel Marketplace integrations, though its strength remains frontend quality rather than backend depth.

Projects connect to GitHub, so generated code lands in a repository and v0 can work as an assistant on an existing codebase rather than only as a standalone builder. Deployment is one click to Vercel, with preview deployments and Vercel's edge network, which is a natural fit for teams already on Vercel and a soft constraint for those on other hosts.

Billing is credit-based, priced per token for each v0 model tier. The free plan includes a small monthly credit amount and a daily message cap; paid plans are per user, include monthly credits plus a daily login bonus, and allow extra credits shared across a team. Business opts out of training by default, and Enterprise adds SAML SSO, role-based access, and support SLAs.
