Lovable vs Polymet

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. Lovable publishes a starting price ($25); Polymet does not. Both have a free tier.

What our research says

Lovable

The cleanest prompt-to-app experience for someone who cannot write React, and GitHub sync means you are not locked in — but 100 credits a month is less runway than it sounds once the app gets real.

Pros

  • Live preview after each change keeps iteration legible to non-developers
  • GitHub sync and Supabase mean the output is real, portable code
  • The free tier is enough to find out whether the idea works
  • Per-action credit costs are published, so estimating is possible

Cons

  • Free tier caps at 30 credits a month regardless of the daily grant
  • Debugging a bad generation can cost more credits than the original build
  • Opinionated stack — React front end, Supabase back end, little room to differ
  • No API for driving builds programmatically

Polymet

Stronger than a generic prompt-to-UI toy because it starts from your design system and can round-trip through Figma, GitHub and Storybook. The blocker for evaluation is that no price exists anywhere in public, so budgeting means emailing sales before you know if it works for you.

Pros

  • Imports your own design system rather than imposing a generic one
  • Two-way Figma import and export
  • Hooks into GitHub, private npm packages and Storybook
  • Visual editor and code editor over the same artefact
  • Real-time team review and shareable live demos

Cons

  • No pricing published at all, on the site or in the docs
  • Credits expire at the end of each subscription term
  • Free-plan output carries a Built with Polymet badge on anything public
  • No API and no offline option

Which one fits

Choose Lovable if you need

  • Founders and designers shipping a working prototype without a developer
  • Anyone who wants generated code exported to GitHub rather than held hostage
  • Small internal tools needing authentication and a database on day one

Choose Polymet if you need

  • Product teams with an established design system and component library
  • Designers who want editable code, not a screenshot to hand off
  • Teams already living in Figma, GitHub and Storybook
