v0 by Vercel

v0 by Vercel is a chat-based UI and app generator that turns prompts (or screenshots) into production-ready React and Next.js code using shadcn/ui patterns. Beyond pure component generation, v0 now plans tasks, runs deployments, connects to databases, and can even build from an iOS app on a phone — making it one of the more complete "prompt-to-running-app" experiences from a major hosting vendor.

Pricing extracted live from v0.dev/pricing (verified 2026-06-01): Free at $0/month with $5 of included monthly credits plus $2 free daily credits on login, Pro at $30/user/month (popular tier, $30 monthly credits, training opt-out by default, additional credits purchasable), Business at $100/user/month ($30 monthly credits per user, centralized billing on Vercel, shared additional credits across the team), and Enterprise (custom pricing with SAML, data-never-used-for-training guarantees).

v0 prices its own models by token, which is unusual transparency for a UI generator: v0 Pro charges $3/1M input tokens and $15/1M output, v0 Max charges $5/1M input and $25/1M output, and v0 Max Fast pushes to $10/1M input and $50/1M output. That matters because heavy iteration can burn through credits quickly — a long chat session redesigning a dashboard can equal a full Pro user's monthly budget.

Where v0 wins: speed from idea to deployable UI, native integration with Vercel hosting and Next.js, image-to-UI (upload a Figma screenshot, get working code), and the iOS app for building on the go. Where it falls short: it heavily nudges you toward Vercel's stack — if you're on Cloudflare Workers, Netlify, or a non-Next.js backend, you'll fight the tool. Designers love it for marketing pages and dashboards; engineers use it for component ideation and rapid prototyping. Not a replacement for a real IDE on long-running projects, but excellent as the first 0-to-1 step.
