Pros
  • Generates React/Next.js + Tailwind + shadcn/ui code with a live preview
  • One-click deploy to Vercel and GitHub sync
  • Free plan includes Design Mode and deployment
  • Builds and deploys apps in the browser, with no setup
  • Handles hosting, databases and deployment in one place
  • Effort levels let you trade cost for capability
Catches
  • Token-based credits: chat history and project context count as input, so long projects get expensive
  • Users report credits burning fast on fixing v0's own errors
  • Free plan is capped at 7 messages a day, and new accounts get only a one-time $5 credit
  • Effort-based pricing: complex requests are billed as one checkpoint that can cost well over $0.25, so cost per prompt isn't predictable
  • Usage beyond the monthly credits is billed unless you set a usage limit in Settings
  • The Register reported customers furious about surprise cost overruns
