Halloy

Halloy’s official documentation describes configuration via config.toml and a built-in Exec Command capability, so enterprise deployments can preseed the config file and automate startup actions such as server joins or NickServ identification without needing interactive setup. I could not verify any vendor-documented Windows installer switches such as silent-install, MSI properties, transforms, or logging options for Halloy itself, so for unattended deployment the safest documented approach is to distribute the app with a managed config.toml and any required theme files, then let Halloy consume that configuration on launch.
