Steam Cloud automatically synchronizes save files across devices, letting you continue games on any computer. Many games support cross-platform play between Windows, macOS, and Linux through Steam’s Proton compatibility layer. Remote Play Together enables sharing local multiplayer games with friends online, while Remote Play Anywhere streams your library to mobile devices.

Community and Social Features

Steam Community connects millions of players through profiles, friend lists, and group features.
