Steam Inventory Helper (SIH)

Steam trading companion: quick sell, mass listing, inventory tools, and market links.

Steam Inventory Helper is a staple extension for anyone living in Steam Community Market and trade offers: it layers shortcuts, pricing helpers and inventory utilities on top of vanilla Steam. It speeds up execution and inventory work — your read on market context still comes from your own research. Always install from the official Chrome Web Store entry and review permissions when Steam updates their pages.

Free; optional donations vary by version — check the store listing.
