About CSGAIN

Built by a CS2 trader who has been writing software for 20 years

SaboFounder and developer of CSGAIN

I've been building software for 20 years, from web apps and APIs to databases and the Linux servers they run on. I play CS2 on FACEIT, trade skins, and use CSGAIN for my own inventory every day. It started as the tool I wanted for myself: real Buff163 prices instead of inflated Steam numbers, honest P&L, and a price history I can trust.

Why I built CSGAIN

Most inventory trackers show Steam Market prices, which include Valve's 15% fee and can't be cashed out. That made my own inventory look worth more than it was. I wanted to see what my skins actually trade for, what I paid for them, and how the value moves over weeks and months. CSGAIN does exactly that, for any public inventory, for free.
