v0 is Vercel’s collaborative AI application builder for developers, designers, product professionals, and teams creating web prototypes. It starts from a conversational prompt or a prepared template, plans work, and generates runnable interfaces, components, and full-stack web applications. A live preview and visual design mode make it possible to refine details after the initial build without leaving the workspace.
Projects can define reusable colors, typography, and styles as a design system, and the agent can connect databases, application services, and APIs while it builds. Code can be synchronized with a GitHub repository, and a completed web project can be deployed to Vercel; creation is also available through the v0 iOS app. Repository synchronization requires a GitHub connection, production publishing follows Vercel’s deployment path, and generated code and integrations still require project-level testing and review.
