V0 is an AI-generated frontend tool launched by Vercel that can generate React and Tailwind CSS code from natural language descriptions. V0 integrates open-source tools such as React, Tailwind CSS, Shadow UI, and other frontend best practices. Currently in beta testing, V0 has already received 100,000 user applications for trial. Vercel plans to introduce a paid subscription to provide more complete features. While V0 lowers the development barrier, the generated code still requires developer oversight.
