I run several Factorio servers for friends and got tired of juggling folders, so I reworked the old Factorio Server Manager (OpenFactorioServerManager) into something that handles multiple servers from one web UI. It’s a fork; credit to the original authors is in the README.

What it does

Multiple servers on one machine, each with its own saves, mods, config and logs

Mod library: every mod version is stored once, each server has a manifest. “Sync from save” reads the mods a save needs and either enables only those (Match save) or just adds them (Add from save). An Apply preview shows what will be added, removed, enabled or disabled before anything touches the server

Scheduled save backups with retention, pin, rename, and restore into any server (including a different one)

Factorio versions are pinned per server, so a new release never silently updates a server.…
