FrameworkScanner

A macOS app that scans installed applications and identifies the development frameworks they use — Electron, SwiftUI, Flutter, Qt, Unity, and more.

Features

• Scans /Applications and ~/Applications with up to 8 concurrent tasks
• Detects 13 framework types: Electron, CEF, Flutter, Qt, Unity, Unreal Engine, .NET/MAUI, Java/JVM, Tauri, Catalyst, SwiftUI, AppKit, and Unknown
• Electron apps show Electron / Chromium / Node.js version details
• Expandable rows reveal embedded frameworks with name, version, path, and size
• Search, multi-filter, and sort by name / size / date / framework
• Stats bar showing framework distribution and total Electron disk usage
• Export results as CSV or JSON
• Light / Dark / System appearance, 8 languages supported

Requirements

• macOS 13.0 (Ventura) or later

Installation

Homebrew (Recommended)

brew tap Geoion/tap
brew install --cask frameworkscanner

After installation, if macOS Gatekeeper blocks the app on first launch, run:

xattr -cr /Applications/FrameworkScanner.app

Why is this needed? macOS automatically adds a com.apple.quarantine extended attribute to files downloaded from the internet. This causes Gatekeeper to block unsigned or ad-hoc signed apps. The command above removes that attribute so the app can launch normally.

Then open the app as usual.

Build from Source

Requires Xcode 15+ and XcodeGen.
