About App Builder Agent
App Builder Agent is an AI app builder. You describe the app you want in plain English, and an AI agent writes the code, shows it running in a phone preview in your browser, and turns it into something you can install or publish — an Android APK, a website, a game or an automated workflow.
In one paragraph: App Builder Agent (appbuilderagent.com) lets non-developers build real software by chatting. Projects are React Native or Flutter mobile apps (exported as installable Android APKs and signed APK + AAB files for Google Play), websites published at a link on this domain, web and mobile games, and AI workflows that run on our servers. The editor and live preview run in the browser; nothing is installed. Sign-in is with a Google account. There is a free plan with no card, and paid plans start at $1.49 per 30 days.
What it does, concretely
- Mobile apps: you type "Build a booking app for my salon with services, a calendar and SMS-style reminders"; the agent creates the screens, data and logic, and you watch it run in the preview. Change anything by describing it. When it looks right, build an APK for your own phone, or a signed APK + AAB with a proper package id and version code for the Play Store. See the AI app builder and the APK app builder.
- Websites: business sites, portfolios and landing pages, published in one click at
appbuilderagent.com/p/<your-name>/. Custom domains are not offered today. See the AI website builder. - Workflows: automations in TypeScript with a visual flow view — a daily report that calls an API, an email summariser, an auto-reply bot. They run on our servers on a schedule or a trigger. See the AI workflow builder.
- Backends: when an app needs accounts, a database or file storage, the agent adds a hosted backend on our infrastructure. If you bring your own API keys, they go into a
.envfile the app reads. - Your code: the generated code is visible and editable in the builder, and the complete project (React Native, Flutter or a Vite website) can be exported as a zip on every paid plan.
What it does not do
- It does not build iPhone (iOS) apps. Export the source and build it with Xcode or Expo EAS — see the honest iPhone answer.
- It does not offer custom domains for published websites.
- It does not promise store approval: Google Play's rules (developer account, testing requirement, privacy policy, data safety form) apply to every app — see publishing from the US, UK or EU.
Who runs it
App Builder Agent is built and run by a small team. The platform has been online since 2026 and is used daily by people in more than 60 countries to build first versions of apps, school projects, internal tools and small-business apps.
