v0 supports Tailwind CSS

v0 is an AI app builder for shipping production apps from a prompt. You describe what you want and v0 generates a working app running in a real environment, with UI, logic, and data wired together. You can start from scratch or point v0 at an existing GitHub repo, where it picks up your environment variables and configuration from Vercel and keeps building on what you've already shipped. From there it plans, reasons, and debugs alongside you as the project grows.

Every prompt creates a branch, opens a PR against main, and deploys on merge. The code lives in your actual repo from the first message, which means product managers, designers, and marketers can ship real features through the same git workflow as engineers, instead of handing prototypes off to be rebuilt.
