Rey is a visual app builder that lets you design, build, and publish native iOS, Android, and web apps without writing a single line of code. Instead of hiring a development team or learning a programming language, you work on a drag-and-drop canvas alongside Rey AI, connect your data, and hit publish — all from your browser.

​
What problem Rey solves

Turning an app idea into a real, published product has traditionally required months of development time and a significant engineering budget — and once shipped, scaling and maintaining it takes even more. Rey removes both barriers. You stay focused on what your app should do and how it should look, while Rey handles the technical complexity underneath: production-ready UI, a managed database, native iOS and Android builds, and one-click submission to the App Store and Google Play. The same project that ships your first prototype is the one that runs your production app at scale.

​
Who Rey is for

Rey is built for teams shipping real products, from a first prototype all the way to production apps running at scale:
  • Founders and startups who need to launch a real, revenue-ready app and keep iterating on it as they grow
  • Product and engineering teams who want to ship features faster without maintaining a bespoke mobile codebase
  • Designers who want to take their Figma mockups all the way to a live, publishable app in the App Store and Google Play
  • Growing businesses who need a custom mobile experience for thousands (or millions) of customers without staffing a full native team
  • Product managers who want to move from prototype to production in the same tool, without a rewrite
No coding experience is required at any step.

How Rey works

Every Rey project brings together three core capabilities:
  1. Visual canvas: Design your app’s screens by dragging and dropping components like buttons, images, text fields, and lists. Rearrange layouts, adjust styles, and see your changes instantly.
  2. Rey AI: Describe what you want in plain English (“a sign-up screen with email, password, and a social login option”) and the agent generates a fully designed screen you can refine from the canvas.
  3. One-click publishing: When your app is ready, Rey packages and submits it to the App Store, Google Play, or the web with a single click — no developer accounts or command-line tools required.
