Useful software

Software a farmer may need besides Crux Panel and CRUX MANAGER.

All of this is optional

You don't have to install these programs. In most cases you don't need them at all: the panel and the manager do the main work.

Program	What it's for
SDA (Steam Desktop Authenticator)	Steam Guard on PC: getting and storing maFiles, 2FA codes, confirming trades.
SIH (Steam Inventory Helper)	Browser extension: item prices from different marketplaces right in the inventory and on the Steam market.
Mem Reduct	Frees up RAM. Helps when there are many windows and RAM is tight.
BES (Battle Encoder Shirase)	Limits the CPU load of processes so windows don't interfere with each other.
SRT (Steam Route Tool)	Choose which Valve servers the game connects to.

What about ASF?

Many people use ASF (ArchiSteamFarm) to farm Steam trading cards. But it links the accounts together: they all run from one program. It's better to farm cards with the built-in feature inside Crux Panel.

Download only from official websites

Stealers that steal maFiles and accounts are often spread disguised as popular programs. Get software only from official websites and GitHub pages.
