Where Logs Go

Platform	Default destination
Linux	stderr (no log file by default)
macOS	~/Library/Logs/jellyfin-desktop/jellyfin-desktop.log
Windows	%LOCALAPPDATA%\jellyfin-desktop\Logs\jellyfin-desktop.log

The active log path is shown in the About overlay (right-click empty space → About).

Rotation

Each run starts a fresh log file. The previous 3 runs are kept alongside the active one with .1, .2, .3 suffixes (oldest dropped). A file also rotates mid-run if it exceeds 10 MB.

Options

--log-file <path>     write logs to file ('' to disable)
--log-level <level>   trace | debug | info | warn | error  (default: info)

On Linux, --log-file is required to write to disk:

jellyfin-desktop --log-file jellyfin-desktop.log
