Guillermo Rauch, founder and CEO of Vercel, discusses v0, an AI tool for generating web apps from prompts, screenshots, or designs. Building on Vercel's infrastructure like Next.js, v0 aims to expand the number of product builders from millions of developers to 100 million by enabling non-coders to ship full-stack products that scale.

v0's origins and expansion strategy

Vercel created v0 to leverage LLMs' strength in JavaScript, React, Tailwind, and Next.js—skills already in training data from open source contributions. It started as a "ChatGPT for web products" post-ChatGPT launch, using multiple models (OpenAI, Claude, Gemini) in a pipeline. Now at 1.3 million users with exponential growth, v0's community feature has 20,000 submissions in under a month, allowing forks like GitHub but for intent-first building: users describe changes (e.g., "change button color, save to database"), inverting traditional Git commits.
