A2UI is a declarative UI protocol designed to enable AI agents to generate rich, interactive user interfaces that render natively across web, mobile, and desktop environments without executing arbitrary code. Instead of relying on text-only interactions or unsafe approaches like sending HTML or JavaScript, A2UI allows agents to communicate UI intent through structured JSON messages that describe components, layouts, and data bindings, which client applications then render using their own trusted, pre-approved components. This approach separates UI generation from UI execution, ensuring that interfaces are secure, consistent with the host application’s design system, and adaptable across platforms. It is designed to be LLM-friendly, using a flat, streaming JSON structure that allows agents to incrementally build and update interfaces in real time, enabling progressive rendering and responsive user experiences.

Huxly is an AI mobile app builder that turns a written prompt or Figma frame into editable app code. Choose Expo (React Native) or Flutter for iOS and Android, or SwiftUI for native iOS. Preview changes in the browser; SwiftUI projects can also run in a streamed iPhone simulator or the Mac Companion. Start from templates or edit source files directly, then export code or push it to GitHub. Huxly connects Supabase or Firebase for authentication and data, adds RevenueCat subscriptions or Stripe payments, and generates backend APIs, webhooks and edge functions. Backends deploy to your own Netlify, Render or Railway account, with secrets kept server-side. Cloud builds support TestFlight, App Store and Google Play submission. Its MCP connector lets Claude Code, Cursor, ChatGPT and Codex work directly on Huxly projects using an existing AI subscription. Huxly serves founders, designers and developers who want to ship mobile apps while retaining their source code.
