  9. A must-have for any Steam trader or collector! Steam Inventory Helper makes managing my inventory and trading on Steam so much faster and easier. The interface is clean and integrates perfectly with the Steam website, saving me a lot of time when selling, buying, or sending trade offers. I especially love the quick-sell and auto-price features — they help me price my items correctly without having to check every single one manually. It also adds some nice quality-of-life improvements, like sorting, bulk listing, and displaying market prices right in your inventory. I’ve never had any problems with it, and it’s completely free. If you’re into Steam trading, or just want to save time managing your skins and items, this extension is absolutely worth installing. Highly recommended!

F.A.Q.

SIH.App is a skin trading platform that works in your browser or as a standalone web tool. It shows live prices for CS2, CS:GO, Rust, and Dota 2 skins in a single feed. The system pulls data from Buff163, Waxpeer, the Steam Market, and more than 30 other trading sites. You can view side-by-side prices, check float values, see trade lock status, and compare listings without switching tabs. Whether you're looking for the lowest CS2 knife price or tracking a rare Rust item, everything is visible at a glance.
If you want to sell skins quickly, use the instant sell option. Just set your price and confirm the trade. It often works faster than the Steam Market. Looking to profit from market gaps? SIH alerts you when prices on Steam and third-party sites don't match. You can buy low and relist elsewhere with a few clicks. For more advanced users, the skin provider API connects directly to trading bots. This makes it easy to automate purchases, resell items, or track price drops in real time. Whether you're flipping CS2 skins on the weekend or running a full-time CSGO trading bot, SIH.App brings all your tools into one place.
Our price comparison supports many popular marketplaces: Buff163, Skinport, CS.Money, Market.CSGO, DMarket, Lis-skins, and others. You can compare prices through a convenient interface or directly on the marketplace’s website.
SIH.Market supports instant item delivery only — this means that in most cases, the delivery takes just a few minutes.
A skin provider is a universal tool for automating item buying and selling for your project. Detailed documentation and 24/7 support will help you set up purchases in less than an hour.
SIH uses its own database with over 1.2 billion unique float records. Convenient filters and search tools help you quickly find all the data you need.
