Steam Library Sync
One click. Every shared co-op game.
The average Steam user owns 90+ games. Multiply that by 4 friends and you're looking at hundreds of titles — but which ones can you actually play together? Steam Library Sync answers that instantly. Paste your Steam ID, and Co-Op Now reads your public game list, filters out single-player titles, and shows you exactly which co-op games your group shares.
How It Works
Paste your Steam ID
Go to Settings, paste your Steam profile URL or vanity name. We resolve it to your 17-digit Steam ID and read your public game list — nothing else.
Your library is mapped
We match your games against our co-op database, filtering out single-player-only titles automatically. Ownership and playtime are imported.
Group overlap appears
Once 2+ members sync, your group page shows every co-op game you share, who owns what, who's missing a copy, and total group playtime per game.
Who Is This For?
Steam Library Sync is built for any group that plays co-op on PC. Whether you're a duo looking for the next game to play or a squad of 6 with years of Steam history, sync lets you skip the guesswork. It's especially useful for groups where not everyone remembers what they own — which is most groups.
Why It Matters
Without library sync, groups waste 20+ minutes every game night debating what to play. With it, you see your shared library in seconds. No more 'does everyone have this?' messages in Discord.
What You Can Do
- Find out your group shares 12 co-op games you never knew about
- See which friend needs to buy a game for the whole group to play it
- Discover co-op games buried in your backlog that you forgot you owned
- Plan purchases — know exactly which game to buy next for maximum group value
Why Co-Op Now Is Different
Other tools make you copy-paste game lists into spreadsheets or manually compare libraries. Co-Op Now does it automatically: sync once, and your shared co-op library stays up-to-date as you buy new games. It works at the group level, not just between two people — so everyone's library is visible in one view.
Trust & Privacy
We only read your public Steam game list. We never access your password, payment info, friend list messages, or any private data. Your Steam ID connects through Steam's official public API — the same data anyone can see on your profile page. We store your game ownership data to show group overlap. You can disconnect your Steam ID at any time in Settings, and your synced data will be removed.
