How it works

Connecting friend sharing enables subscription sharing for Workshop games by default. You can limit the game’s audience or turn sharing off in its Sharing menu. New named lists start private, and each list can be shared with all connected friends or selected friends. A private list does not hide items already shared through your subscription inventory. Local download history stays on your PC.
Automatic synchronization starts off for every game. Browsing, selecting, and one-time installs don’t turn it on. To keep up automatically, follow the friends or lists you want and separately enable that game’s Auto-sync switch.
Both players need WorkshopSync to browse each other’s shared subscriptions and lists. If a friend doesn’t use it, you can still paste the Workshop links they send and subscribe to the items together.
Steam friends who have connected to WorkshopSync and are sharing items for the selected game. It doesn’t check whether mods work together. Dependencies, load order, and game versions still depend on the game.
The app checks on startup and hourly while open. Each update is checked against a signed release catalog and installer checksums before it can run. This is separate from a Windows publisher certificate. Choose Download update, then Restart & update when you’re ready.
No. WorkshopSync is an independent companion and is not affiliated with Valve. Steam and Steam Workshop belong to Valve. Workshop items remain the work of their respective creators.
