What v0 is in 2026
v0 is Vercel's AI design-to-code tool. The output is React + Tailwind + shadcn/ui — currently the dominant new-app stack — and the visual quality consistently beats every other AI UI generator.
The honest take
For React/Next.js developers, v0 is the right AI UI tool. For full-stack apps, pair with Lovable or your IDE.
