About Fladder
Fladder is an open-source, cross-platform frontend for Jellyfin, built with Flutter. It plays media from a Jellyfin server through direct, transcoded or offline playback and can sync content locally to a device; it also supports library management such as refreshing content and editing metadata, multiple users and servers, intro/credit segment skipping, Trickplay timeline scrubbing, keyboard shortcuts and comic book files in .cbz and .cbr formats.
Builds are offered for Android (including TV), iOS, web (also via Docker), macOS, Windows and Linux, and the project is licensed under GPL-3.0. Chromecast support is listed as a planned feature. The web build hosted on GitHub only allows HTTPS connections, though self-hosted versions can use HTTP, and Windows Defender may mark some Flutter applications as false positives.
