ASF is a C# application that allows you to farm steam cards using multiple steam accounts simultaneously. Unlike Idle Master which works only for one account at given time, requires steam client running in background, and launches additional processes imitiating "game playing" status, ASF doesn't require any steam client running in the background, doesn't launch any additional processes and is made to handle unlimited steam accounts at once. In addition to that, it's meant to be run on servers or other desktop-less machines, and features full cross-OS support, which makes it possible to launch on any .NET Core-supported operating system, such as Windows, Linux or OS X. ASF is possible thanks to gigantic amount of work done in marvelous SteamKit2 library.

ASF doesn't require and doesn't interfere in any way with Steam client. In addition to that, it doesn't require exclusive access to given account, which means that you can use your main account in Steam client, and use ASF for idling the same account at the same time. If you decide to launch a game, ASF will get disconnected, and resume idling once you finish playing your game, being as transparent as possible during entire process.
