v0 is an AI-powered tool developed by Vercel that helps developers rapidly create user interfaces and prototype applications. It generates production-ready code using open-source technologies like React, Tailwind CSS, and Shadcn UI, based on user descriptions or images of desired layouts. v0 offers a chat-based interface where users can input prompts and receive responses in the form of text, code, or specialized content called “Blocks”. This tool is particularly useful for quickly building initial versions of products, streamlining the process from design to deployment, and allowing developers to focus on refining their ideas without getting bogged down in initial coding tasks.
