Akiora is a fast, customisable anime player that brings cataloguing, streaming, danmaku, tracking, and watch-together into a single polished interface. Define your own video sources with a concise XPath rule format, watch in sync with friends, and enjoy real-time AI-powered upscaling on hardware as light as a phone.
- Custom rule engine — Define video sources with up to five lines of XPath selectors. Rules can be imported, exported, and shared.
- Built-in player — High-quality playback powered by libmpv. Hardware decoding, HLS support, ad filtering, and per-source playback overrides.
- Real-time super-resolution — Anime4K-based upscaling with quality and performance presets.
- Danmaku — Bullet-comment overlay with full style controls, keyword and regex blocklists, deduplication, and adjustable timing.
- Watch tracking — Personal watchlist with optional cross-device sync via Bangumi or WebDAV.
- Watch Together — Synchronised playback over the SyncPlay protocol with public and self-hosted servers.
- Image search — Identify any anime from a screenshot via trace.moe integration.
- Offline downloads — Per-episode or full-season downloads with adjustable concurrency and segment-level retries.
- DLNA casting and external player hand-off.
- Adaptive UI — Material You dynamic colour, OLED-friendly dark mode, high-refresh-rate support, custom title bars on desktop.
| Platform | Minimum version |

Pre-built binaries for each supported platform are published on the Releases page.
iOS builds require self-signing before sideloading. Linux users should prefer the
.debpackage; the.tar.gzis intended for repackaging only and lacks system-tray and icon integration by design.
flutter pub get
dart run build_runner build --delete-conflicting-outputs
flutter runA current Flutter SDK is required, along with the standard platform toolchain you target (Android Studio for Android, Xcode for iOS/macOS, Visual Studio with C++ tools for Windows, GCC + GTK for Linux).
App icons across every platform are regenerated from assets/images/logo/ via:
dart run flutter_launcher_iconsAlmost every behaviour is exposed through the in-app Settings menu, including:
- Video renderer and hardware decoder selection
- Super-resolution mode (off / performance / quality)
- Danmaku styling and shielding
- Download concurrency (per episode and per segment)
- Network proxy
- Sync providers (Bangumi token, WebDAV endpoint)
- Default startup screen, theme, and accent colour
For source-rule authoring, see the bundled examples and the Rule Editor page inside the app.
Why does playback stutter when I enable super-resolution?
Super-resolution is GPU-bound. On laptops or integrated GPUs, prefer the Performance preset. Applying super-resolution to lower-resolution sources is dramatically cheaper than applying it to high-resolution sources.
Memory usage during playback looks high.
The player aggressively buffers video to deliver smoother playback and faster seeking. On constrained devices, enable Low Memory Mode under Player Settings to bound the cache.
An external player can't open one of my videos.
Some sources require anti-hotlinking headers or cookies to deliver media. The built-in player handles this transparently; most external players cannot.
How do I write a custom rule?
Rules are five short XPath selectors targeting search results, episode lists, and the final stream URL. Only selectors starting with // are supported. Use one of the bundled examples as a template and verify the rule with the in-app Test tool.
I'm building from source and the build fails.
In addition to the Google-hosted Flutter dependencies, the build pulls native libraries from MavenCentral, GitHub, and SourceForge. If you are on a restricted network you may need to configure mirrors for those hosts.
Issues and pull requests are welcome. For new video-source rules in particular, please include a brief description and a sample query so reviewers can validate the rule end-to-end.
Akiora does not collect telemetry or personal data. Preferences and watch history are stored locally; optional sync flows go directly through the third-party services you configure (Bangumi, WebDAV, SyncPlay) and never touch any first-party server.
