App Builder Agent

What App Builder Agent is

App Builder Agent is an AI app builder that runs entirely in the browser. You describe the app you want in plain English, and an AI agent writes the code, shows it running in a phone preview, and turns it into something you can install or publish: an Android APK, a website, a game or an automated workflow. The site's tagline is "Describe it. The agent builds it." It is written for people who are not developers, such as a founder with a first app idea, a freelancer prototyping for a client or a small business that wants a simple site or automation, and it also gives developers an exit through exportable source code. The pages do not say where the company is based.

What you build and how

The editor is a chat plus a live preview. The home page's example prompt is "Build a habit tracker app with streaks and reminders," with buttons for a mobile app, a website, a game or a workflow. The agent writes the code, you watch it run in the phone preview, and you keep describing changes. The home page says nothing needs installing: the editor, the device preview, the backend, the database and the workflow runner all run in your browser, and the editor and preview work without an account.

Mobile apps. The About page says the builder produces installable Android apps, and the guides say it writes Flutter or React Native code. Any plan can produce a signed APK and AAB for Google Play. The free plan includes a free APK download so you can install the app on your own phone, and the pricing page says the APKs you build carry no per-app fee. Google Play's own one-time developer registration, US$25, is paid to Google, and Apple's program fee is paid to Apple.

What it does not build. The About page is plain that it does not build iPhone (iOS) apps. The route it describes is to export the source and build it with Xcode yourself. If an iOS release is the point of your project, that caveat comes before everything else here.

Websites. The AI website builder is one of the 4 product pages listed in the site menu. Websites published on the platform carry no per-app fee, and the About page says a website project is a Vite site that can be exported as a zip. The guides compare the product with site and app builders such as Adalo, Bubble, FlutterFlow and Glide. The comparisons frame those tools as drag-and-drop, visual or spreadsheet builders and this one as description-driven with exportable code.

Games and workflows. Games run in the browser. The AI workflow builder covers automations such as a mail summarizer or an auto-reply bot, which run on the company's servers on a schedule or a trigger.

Backends and data. When an app needs accounts, a database or file storage, the agent adds a hosted backend on the company's infrastructure. If you bring your own API keys, they go into a .env file the app reads. The pages do not list named integrations.

Code ownership. 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. The pricing page says "Your code is yours." The site also reports that it is itself "built with App Builder Agent," as its footer puts it.

Support. The About page says there is a support panel inside the builder that opens a chat with the team.

What the pages say about plans

The pricing page says every plan gives you the whole product: the AI agent, the live preview, Android builds, websites, games and workflows. Plans differ in the monthly AI allowance, how many APK builds you can make and whether you can export source code. Prices are in US dollars, with India billed in rupees at the equivalent price.

• Free. $0, with 500K AI tokens a month, every feature, a free APK download and no card required. The Free plan counts as the trial. Android builds are capped at 5 in total.
• Member. $1.49 per 30 days, with unlimited APK builds and unlimited source code export. The AI allowance is stated two ways: the home page says 2M AI tokens a month, while the free plan guide says 5M AI tokens for 30 days. The pages disagree, so check the pricing page at purchase.
• Pro. $5.72, with 20M tokens a month.
• Max. $11.01, with 100M tokens a month.

Every bigger plan includes the Member features. Plans do not auto-renew: when a 30-day period ends you keep your projects and drop back to the Free plan until you pay again. The free plan guide, updated September 11, 2026, estimates that a small app typically takes a few hundred thousand tokens to build and iterate, so the free allowance covers a first app in most cases. It also notes that the 5-build cap is used up quickly by test and store builds, which is why a person publishing to Google Play will want Member.

The pages state no compliance certifications, no customer counts and no hosting regions.

Who it suits and who it does not

A solo founder who wants an Android MVP on their own phone this afternoon can get there with the free plan and no card. A freelancer can prototype a client's site or small app and hand over the exported source. A small business owner can try a scheduled automation such as an auto-reply bot. Because Member costs $1.49 per 30 days with no auto-renewal, the cost of publishing an app is small, and the site says there are no per-app fees on what you build.

The caveats are specific. There is no iOS build, so an iPhone-first product needs Xcode and the exported source. The generated stack is Flutter, React Native or Vite, so someone who maintains it later will need those skills. The pages describe a hosted backend and database but not data limits, compliance certifications or team permissions, so an IT group choosing a governed platform for many builders will find little to evaluate here. And since the two pages quote different monthly token allowances for Member, confirm the figure on the pricing page before you plan a heavy month of building.
