Build and ship real iOS & Android apps from a chat prompt
Chat with an agent that writes and edits your mobile app's code in real time, so changes appear as you describe them.
a0.dev handles the build, creates your App Store Connect listing, and uploads the app for you.
Set up in-app payments and subscriptions without wiring together separate payment tooling.
Develop against Convex or Supabase backends and use built-in APIs for AI inference and image generation.
Describe an app in chat and ship it
Describe your product in natural language and AI agents produce a functioning app rather than snippets or mockups.
Frontend and backend are generated together, so apps have real logic, data handling, and connectivity, not just UI.
Generated apps are deployed to a live URL right away, so you can share and test without setting up infrastructure.
The output is a standard codebase you can download, edit, and move into your own toolchain or repository.
Generates polished full-stack web applications faster, but offers less granular control over raw backend code configuration.

SpecialistThe AI coding agent for building ambitious software

Focuses heavily on business applications and workflows, but lacks the deep custom UI styling flexibility of Emergent.

Delivers a more comprehensive cloud development environment with agentic coding, but has a steeper learning curve.
Provides instant in-browser full-stack prototyping, but requires more manual intervention for production-grade database scaling.
Excels at generating modern React user interfaces instantly, but requires separate backend integration for full-stack deployment.
Specializes specifically in generating native Swift and Kotlin mobile applications directly from text prompts.

Includes built-in database and payment integrations out of the box, but has a smaller community ecosystem.

SpecialistTransforms spreadsheet data into business apps rapidly, but is less suited for building custom greenfield web applications.

Generates native mobile and web applications from conversational prompts with quick setup and deployment.

AI no-code builder that turns one sentence into native iOS, Android, and web apps
SpecialistProvides advanced visual low-code editing and full code export, but depends more on manual visual configuration.
