Ever wondered what technology powers your favorite apps? BuiltWith instantly
reveals the development framework behind every app installed on your device.
🔍 WHAT IT DOES
BuiltWith scans your installed apps and identifies the framework each one was
built with — no internet required, no data leaves your device.
Detected frameworks include:
• Flutter
• React Native
• Unity
• Xamarin / .NET MAUI
• NativeScript
• Capacitor
• Cordova / Ionic
• Native Android (Java / Kotlin)
👨💻 BUILT FOR DEVELOPERS
Researching a competitor's tech stack? Curious whether that smooth app is
Flutter or native? Evaluating frameworks for your next project? BuiltWith
gives you real answers from real apps already on your device.
• Browse your full app inventory — user apps and system apps
• Filter by framework to see all Flutter apps, all React Native apps, and more
• Search by app name or package name
• Tap any app for a detailed framework breakdown
🔒 PRIVACY FIRST
BuiltWith is fully on-device. Here's exactly what happens when you scan:
• Your installed app list is read locally
• Each APK is inspected for framework fingerprints
• Results are displayed to you — and only you
• Nothing is uploaded, stored remotely, shared, or sold
• No account required. No analytics. No ads.
You'll see a clear disclosure before any scan begins. You stay in control.
⚡ MODERN & FAST
Built with Jetpack Compose and Material 3 for a clean, fluid experience.
Detection runs entirely in the background so the UI stays responsive even
across hundreds of installed apps.
📋 PERMISSIONS
BuiltWith uses the QUERY_ALL_PACKAGES permission. This is the only way to
enumerate all installed apps on your device — the core purpose of the app.
This permission is used solely to list and inspect apps for framework
detection. Nothing else.

what's running on your phone — BuiltWith gives you a clear, honest look at
the technology stack behind every app on your device.
