Everything you need to build, nothing you don't.
Design-to-code
Import design tokens and Figma frames. Designers and engineers work from the same source of truth.
Connect any datasource
Postgres, REST, GraphQL, gRPC, or your own SDK. Queries are typed and cached out of the box.
Git-native workflow
Everything is code. Branch, review, and roll back tools the same way you ship your product.
Edge runtime
Functions deploy to the edge automatically. Sub-50ms responses for tools your whole team relies on.
