-h --help Get this help message. -c --configuration Path to the configuration file. -a --apps Path to the NymphCast apps folder. -w --wallpaper Path to the wallpapers folder. -r --resources Path to the GUI resources folder. -v --version Output NymphCast server version and exit.
Self-hosting gives you three things SaaS can’t: data ownership (the files live on disks you control), cost predictability (a one-time setup vs. recurring per-seat fees that grow with your household or team), and longevity (open-source means the app keeps working even if the maintainers move on, since you can pin a working version). The trade-off is that you take on the operational work of running a server, applying updates, and handling backups.
Memory requirements depend on the NymphCast Server configuration: by default the ffmpeg library uses an internal 32 kB buffer, and the server itself a 20 MB buffer. The latter can be configured using the (required) configuration INI file, allowing it to be tweaked to fit the use case.
