Flangapp PRO - Convert website to mobile app SAAS

Flangapp AI is a self-hosted SaaS script that turns any website into an Android and iOS app. Paste a link, describe what you want in plain language, and the built-in AI configurator sets up the app for you: navigation, colours, tabs, splash screen, even a dark theme for the website inside the app. Check the result in a live preview on real devices, then build, sign and publish without a Mac. Sell the service to your own customers with subscriptions or one-time plans.

See how it works

Watch the short video: how Flangapp AI turns a website into an app.

Meet the AI configurator

Open an app, choose Flangapp AI in the app settings and just write what you need. The assistant reads the current settings, inspects your website, applies the changes and tells you what it did. You can paste screenshots into the chat, and it suggests example requests written for your particular site.

• App settings: general info, design and template, side menu, navigation and bottom tab bar, permissions, splash screen, app texts.
• Your website inside the app: custom CSS and JavaScript for colours, fonts, a dark theme, hidden headers, footers, cookie banners and pop-ups.
• Site check: shows whether your website can be restyled inside the app before you spend any credits.
• Honest limits: the assistant works only within what the Flangapp template can do. It never edits the app’s source code or the website’s own content, and it warns you when a request is not possible.

Live preview on real devices

The preview streams the real app running on an Android device or an iOS simulator, right next to the chat. After every change the app restarts by itself, so you see the result in seconds. Preview builds don’t need signing keys and don’t use your build quota. Prefer your own phone? Scan the QR code with Expo Go.

Pay-as-you-go AI credits, no API keys

You don’t need accounts with AI providers. Activate your license and the AI is connected to the Flangapp billing service. The chat and the live preview share one balance of credits: every license includes 1,000 welcome credits (a $5 USD value) to test everything live, and you can top up by card at any time. Choose from four model levels: Level 3 is recommended, Levels 1 and 2 are cheaper and simpler, Level 4 is for the hardest requests. Every charge is listed in the credit history. The AI features are optional: you can still configure every app manually in the control panel.

From URL to app in 3 steps

Enter a name and a link, describe the changes in chat, then preview and build. It works with any website on any CMS: WordPress, Shopify, Wix, Webflow, Squarespace, Joomla and more.

Turn it into a business

• Create your own subscription and one-time plans (a fixed number of builds).
• Give free builds to any customer with gift plans.
• Accept payments with Stripe, PayPal, Razorpay, Paystack or cash.
• Money goes straight to your own payment accounts.

Publish without a Mac

Upload your Android and iOS signing keys once, and Flangapp signs and builds the apps automatically through GitHub and Codemagic: APK, AAB and IPA files, ready for Google Play, TestFlight and the App Store. Builds target Android 16 (API level 36) and the latest iOS SDK, so they meet current store requirements. No Android Studio, no Xcode, no Mac.

A complete admin panel

Dashboard with a sales chart, customers, apps, support tickets, plans, transactions and payment providers, in light and dark themes. Add administrators to your team, upload your own logo and set your own project name.

Everything a real app needs

• Bottom tab bar, top bar and side menu with a big icon collection.
• Free push newsletters for Android via OneSignal, managed inside the panel.
• Location, camera and microphone permissions generated automatically.
• White label: your logo, launch icon, splash screen and colour scheme, with no extra copyrights.
• Editable app texts and offline screen, ready for localization.

Built for developers

You get the full source code: a PHP 8 / CodeIgniter 4 backend, a Vue 3 + Vuetify 3 frontend and the Flutter (Dart) app template. Everything runs on your own server, so your data stays under your control. API methods are commented, and you can change any part of the code, or use your own design and app templates.

What’s included and what to expect

Included with the license

• Full source code: PHP API, Vue 3 frontend, Flutter app template
• Flangapp AI chat configurator and live preview, plus 1,000 welcome credits
• Admin panel with customers, apps, plans, tickets and transactions
• Subscription, one-time and gift plans; Stripe, PayPal, Razorpay, Paystack and cash payments
• Android and iOS key manager, APK / AAB / IPA builds
• Android push newsletters, setup wizard and documentation

Server requirements

• PHP 8.2, MySQL with the MySQLi driver, OpenSSL, at least 2 GB of RAM
• 2 domains or subdomains with SSL certificates (free Let’s Encrypt works), cron support
• A GitHub account and a Codemagic account
• No server of your own? Easy-Install hosting offers 3 months of free hosting with automatic installation.

IMPORTANT, please read

• One regular license covers one domain, with an unlimited number of customers and apps. Each new domain or project needs its own license.
• The AI chat and the live preview run on prepaid credits (1,000 welcome credits are included). Extra credits are bought separately by card.
• The apps work on Android and iOS using WebView technology.
• Flangapp integrates with external services: GitHub (stores the apps’ code), Codemagic (builds and publishing), Expo (QR preview) and OneSignal (Android push). Codemagic includes 500 free build minutes per month; usage above the limit is billed by Codemagic. The terms of these services can change at any time, and the author cannot control or guarantee their uninterrupted work.
• To publish, you or your customers need Apple and Google developer accounts.
• When using the embedded webview for Google Sign-In, some websites may return a 403 disallowed_useragent error. This is a restriction imposed by Google and is not related to Flangapp. Try signing in with a standard browser, check your Google account security settings, or contact the support team of the target service.

Changelog

25.09.2026 Update 4.0.2
- Android and iOS builds of apps that were built before the update no longer fail with
  "Failed to merge branch." Before a build, the app's branch in your build repository
  is brought up to date with main. When that merge conflicts (the app's own
  build.gradle.kts against the template's API 36 change), the branch now starts again
  from main; the build then uploads the app's files as usual.
24.09.2026 (Flangapp AI, Update 4.0.1 PRO)
- GitHub Repository Updates no longer stops with
  CONFLICT (modify/delete): android/app/build.gradle.kts deleted in HEAD and modified in template/main.
  The update no longer deletes that file from your build repository, and a merge conflict
  is now settled with the template's version of the file.
