a0.dev

Paid

a0.dev is a platform for building iOS and Android apps through chat. You describe what you want, and an AI agent writes React Native code in real time. It is for App and Website Builders work.

The platform handles the parts that slow mobile development down: provisioning, builds, and app store submission. You get working code you can export, not a locked-in template.

It only makes mobile apps. If you need a web app, this is not your tool.

Open it if you need a published mobile app without Xcode or Android Studio. Skip it if you need web apps or custom backends.

You will get the most from it when this is your situation.

• Non-developers wanting published apps without coding: You describe features in plain language. The system writes the code and handles app store submission.
• Non-technical founders who want to ship iOS apps quickly: You skip months of learning mobile development. Your app can be live in days.
• Indie hackers validating mobile app ideas: You test concepts fast without hiring developers. You keep ownership of the code to iterate later.
• Developers tired of App Store provisioning complexity: You stop wrestling with certificates and profiles. One click handles submission.
• Side project builders shipping to both stores: You build once and publish to iOS and Android. No separate toolchains to maintain.
• Web developers without React Native experience: You use your existing logic knowledge. The platform translates to mobile components.
• Startup founders validating mobile MVPs: You get to market before spending on a dev team. Real user feedback comes faster.
• Digital agencies delivering quick client MVPs: You show working apps in days. Clients understand tangible previews.

These are what matter after you have used it for real projects.

• One-click publishing to app stores: You skip Xcode, Android Studio, and manual provisioning. Your build goes straight to App Store Connect and Google Play Console.
• Real code you own: On the Pro plan, you export React Native/Expo source. You can leave the platform and continue in any editor.
• Built-in backend support: Convex and Supabase integrate directly. Auth, database, and APIs come from prompts, not configuration files.
• Mobile tester app: You preview on your actual phone without simulator setup. No Expo Go pairing or device registration hassles.
• Live iteration: The AI agent debugs and modifies while you test. You describe changes and see results without rebuilding.

The flow is straightforward.

1. Sign up and describe your app idea in chat.
2. Review the generated React Native code and live preview.
3. Iterate by asking for changes until the app works as you want.
4. Connect your App Store and Google Play accounts.
5. Click publish to build and submit to both stores.

Skip it when these limits matter to your project.

• Web apps only: It does not make web apps at all. You get mobile binaries, not browser sites.
• Daily message limits: Vague prompts burn through your allowance fast. Complex projects need careful planning or higher tiers.
• Limited backend depth: Custom APIs and microservices are beyond scope. Standard backends work; custom architecture does not.
• AI context limits: Large projects can lose state or overwrite files. You need to manage project size and save checkpoints.
