Open Source & Third-Party Software
What Feint — and this site — are actually built on. Compiled directly from each project's real dependency manifests (Xcode's Package.resolved, Android's build.gradle.kts, and this site's own package.json), not guessed.
What this page is (and isn't)
This is a transparency page for you, not a legally-complete NOTICE file bundled inside the app installers — that's a separate, more exhaustive, typically machine-generated artifact we handle independently. Some libraries below aren't bundled inside Feint at all (you install them yourself, or they're called over the network) — they're listed anyway so you know what powers the functionality you're using, even where no attribution is legally required.
Feint for Mac
| Library | What it's for | License | Bundled? |
|---|---|---|---|
| Firebase Crashlytics | Crash reporting | Apache 2.0 | Yes |
| pymobiledevice3 | Real iPhone tunnel + location simulation | GPL-3.0 | No Installed separately via pip |
| scrcpy | Android screen mirroring | Apache 2.0 | No Installed separately via Homebrew |
| UxPlay | Wireless iOS (AirPlay) mirroring | GPL-2.0 | No Installed separately via Homebrew |
| Android Debug Bridge (ADB) | Android device control | Apache 2.0 | No Part of your own Android SDK |
| OSRM | Free route road-snapping (public demo server) | BSD 2-Clause | No Called over the network, not bundled |
pymobiledevice3 and UxPlay are GPL-licensed, but neither is bundled or distributed by Feint — you install them yourself via pip/Homebrew — so no copyleft obligation is triggered. They're listed purely so the underlying pipeline isn't a black box.
Feint Companion (Android)
| Library | What it's for | License | Bundled? |
|---|---|---|---|
| osmdroid | Standalone map picker | Apache 2.0 | Yes |
| ZXing (zxing-android-embedded) | QR code pairing scan | Apache 2.0 | Yes |
| Firebase Crashlytics | Crash reporting | Apache 2.0 | Yes |
| AndroidX Jetpack libraries | Core Android framework support | Apache 2.0 | Yes |
Also uses Google Play Services (Location) for device location APIs — that's Google's own proprietary SDK, governed by Google's SDK terms rather than an open-source license, so it's disclosed here separately from the OSS entries above.
iOS Companion
No third-party dependencies at all — pure SwiftUI and Apple system frameworks (CoreLocation, Network, ReplayKit).
