Capacity vs v0

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. Capacity starts at $25, v0 at $30. Both have a free tier. Only v0 ships a public API.

What our research says

Capacity

A reasonable on-ramp for non-coders who want a working app with accounts and payments rather than a static prototype, and unused credits never expire. The catch is variable credit burn per AI message, which makes the real cost of iterating hard to predict, and code export is locked behind the $69 tier.

Pros

  • Generates deployed apps with auth, data and payments, not just mockups
  • First app is free to try without a credit card
  • Credits roll over indefinitely, including one-time packs
  • Full codebase export available on Growth and above

Cons

  • Credit consumption per request is variable and opaque
  • Cheapest tier cannot export code or use custom domains
  • Share of the no-code app market is crowded with better-funded rivals

v0

The strongest choice when the target stack is Next.js on Vercel, since generation, preview and deployment live in one loop and the Platform API lets you embed the whole builder. Costs are credit-metered per token, so long agentic sessions eat the included allowance fast, and output is opinionated toward Vercel's stack.

Pros

  • Generates deployable full-stack code, not static mockups
  • Free tier plus daily login credits support light ongoing use
  • Documented Platform API and SDK for programmatic generation
  • Design Mode and screenshot-to-UI shortcuts help non-coders

Cons

  • Credit consumption is hard to predict on bigger builds
  • Training opt-out is default only on Business and Enterprise tiers
  • Output leans on Vercel deployment and ecosystem conventions

Which one fits

Choose Capacity if you need

  • Non-technical founders validating an app idea end to end
  • Simple internal tools that need logins, stored data and payments
  • Builders who prefer paying for stored credits over a metered monthly quota

Choose v0 if you need

  • Founders and PMs producing working MVPs and internal tools from prompts
  • Frontend engineers scaffolding shadcn/Tailwind components
  • Developers embedding text-to-app generation via the Platform API
