v0 works at the interface layer: give it a requirement or a screenshot and it produces React and Tailwind-style component code, lets you adjust spacing, colors and interaction states in chat, then take the code into your project. It covers UI, not whole-site generation; business logic and data APIs are yours. Component-sized use works best, since filling a whole page then fixing it is painful; check the stack matches your project.
What it does
- Frontend component code from text or screenshots
- Chat-based tuning of styles, states and interactions
- Component-sized output for existing projects
- Connects to Vercel deployment flows
- Review before taking the code
Who it is for
- Missing a form and list for an admin page
- A design or screenshot to turn into working components
- Several interface layouts quickly at prototype stage
- Frontend capacity is tight and the view layer comes first
How to get started
- Build one component at a time with clear state and interactions
- Run it in your project to confirm style dependencies match
- Copy what you need and tidy by hand instead of pasting whole blocks
