Jellystack
Jellystack is a privacy-focused Jellyfin and Seerr client with a native Android experience. Browse and play your own media, manage requests, download for offline use, and keep playback state in sync—without a Jellystack cloud, ads, analytics, or tracking.
Highlights
- Jellyfin libraries, favourites, watched state, progress, search, and Quick Connect
- Direct Play and HLS playback with audio, subtitle, and quality selection
- Offline downloads stored in app-specific storage
- Seerr discovery, requests, seasons, request status, trailers, and recommendations
- Cinematic details with cast, ratings, streams, collections, and similar titles
- Phone and tablet layouts, English and German, light and dark themes
- Contextual Cast permissions and an optional biometric app lock
- A remote-first Android TV, Google TV, and Fire TV interface in closed beta
Android is the stable, published platform. The shared Kotlin Multiplatform code and iOS host remain experimental; iOS is not currently distributed as a supported release.
Privacy
Jellystack connects directly to servers configured by the user. Server credentials and tokens are stored in the platform-protected credential store. The app has no analytics SDK, automatic log upload, advertising, or developer-operated media proxy.
See Privacy, Permissions, and the German privacy policy.
Build
Requirements:
- JDK 17
- Android SDK API 36
- Xcode on macOS for iOS targets
All Gradle commands run from the repository root:
./gradlew :app-android:assembleDebug
./gradlew :app-tv:assembleDebug
Useful verification:
./gradlew spotlessCheck detekt
./gradlew :app-android:check
./gradlew :shared-network:jvmTest :shared-core:testDebugUnitTest
See Building for local setup and Architecture for module boundaries.
The TV beta uses a separate GMS-free application module while sharing Jellyfin, Seerr, settings, and playback logic with mobile. See Android TV and Fire TV for emulator setup, remote controls, builds, testing, and store submission.
