Vercel v0 is a generative UI (User Interface) tool developed by Vercel. It allows developers and designers to create web interfaces by describing them in natural language or by providing existing mockups/images. v0 then generates code primarily using React, Tailwind CSS, and Shadcn UI. The aim is to accelerate the initial phase of UI development, enabling rapid prototyping and iteration. Users can select from generated options, refine them within v0, and then copy the code into their projects for further development. It's positioned as a tool to build the first iteration of a product or specific UI components quickly.
