Most settings are configurable entirely via UI (or the Settings.fds
file) and generally most users never need to touch the CLI - however a few key settings intended for automated or dev usage are provided by command line instead (notably the path to the settings file itself for example). Additionally, some settings in the UI can be overridden by command line (eg host/port).
An example for a personal developmental launch configuration on a home Windows PC would be .\launch-windows-dev.ps1 --host * --port 7850 --environment development --launch_mode web
Note that if your inputs are invalid, the program will refuse to start, with an error message indicating what value is wrong.

If you need to set environment variables for the Comfy backend - just set them before launching Swarm. Any envvars set for Swarm will be automatically transferred down to the backend process when it's launched.
