v0.app by Vercel
The AI builder for everyone
Visit website →About
v0.app is Vercel's AI builder for web software. A prompt, sketch, or screenshot becomes working front-end code, and v0 can also scaffold full-stack features with data, authentication, and API routes.
Output is standard React and Next.js that matches common design systems, so a developer can copy components into an existing project or keep iterating in v0 and deploy straight to Vercel. The chat keeps context across a build, and generated UI can be refined visually or by instruction.
It is aimed at developers who want to move faster on UI work and at designers and product people who want to produce real, deployable interfaces without writing everything from scratch.

Why we picked it
v0 earns its spot for producing standard React and Next.js that matches common design systems — code a developer can actually copy into an existing project is worth naming against builders whose output only makes sense inside their own walled editor.
