FeatherQuilld

FeatherQuilld is the .NET daemon that runs WebSpaces for FeatherPanel web hosting, with a reverse proxy, SFTP and FTP, backups and optional mail.

FeatherQuilld does for websites what FeatherWings does for game servers. It runs on a web node, takes orders from the panel over an HTTP API, and runs each WebSpace (one hosted site) in its own Docker container.

What it manages

• WebSpaces: create, start and stop, reinstall, logs, a websocket console, resource usage and transfers to another node.
• A reverse proxy in front of the WebSpaces: Caddy (default), nginx or Traefik, set by system.proxy.provider. It routes each domain to the container’s loopback port (20000 to 29999) and handles Let’s Encrypt or a custom certificate per WebSpace.
• File access over SFTP (port 2222) and FTP (port 21, passive 50000 to 50100), plus the panel’s file manager.
• Backups, restores and imports per WebSpace, schedules, a per-WebSpace Redis and a malware scan.
• DNS and mail endpoints. Mail runs through docker-mailserver (default) or mailcow. See Mail.

It is a .NET application published as one binary, featherquilld, with a quilld alias and the fqctl tool. It runs as root because it manages Docker and bind mounts.
