Want to play a multiplayer or co-op game with friends, but don't know which ones you have in common? Friend search will instantly show which games everyone in the group already owns - and even filter them further by genre!

Have a big game library, but can't find anything to play? You can limit your searches to just the games you own, while still using all the fancy search filters.

Have you noticed the Steam Summer/Winter sales constantly feature the same games on the front page year after year? We let you easily filter by year, discount, and rating, blocking unwanted items with a single click.
