Use tool ↗About Polymet
Polymet is an agent that produces product design work together with the frontend code behind it. You point it at an existing design system, ask for a page, a component or a variant, then move between a visual editor for layout, spacing and colour and a code editor for the source. It imports and exports Figma files and connects to GitHub, public or private npm packages and Storybook, and teams can review together and share live demos with stakeholders. Polymet AI, Inc. works out of San Francisco and came through Y Combinator's 2024 summer batch. Subscriptions are metered in credits, but no figure is published anywhere: the free plan stamps a Built with Polymet badge on public work, and paid rates come only by asking.

Pros & cons of 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
Best for
- 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
Not for
- Solo builders who just want a deployed app from a prompt
- Buyers who need a published price before starting a trial
Watch out: The terms state prorated refunds are not issued for unused portions of a subscription period, and unused credits expire with the term.
