CS2 Trader Inventory Value Tracker

Track your Steam CS2 inventory value over time. A companion to CS2 Trader that adds value-history graphs and exports.

A lightweight companion to the CS2 Trader (csgotrader.app) extension. ⚠️ REQUIRES CS2 Trader. This add-on does nothing on its own — install and enable CS2 Trader first. It reads the inventory total that CS2 Trader shows on a Steam CS2 inventory page and turns it into a value-history graph. WHAT IT DOES • Adds a "+" button next to the Total Inventory Value on any Steam CS2 inventory. Click it to start tracking that account. • Saves one snapshot per day — total value, item count, and each item's name + price + float. • Draws a Steam-styled graph above the page: a price line over time plus per-day item-count bars, with 7d / 14d / 30d / All ranges and a hover tooltip. • Export any day to CSV / Excel / plain text, or download a full JSON backup. • A toolbar popup lists every tracked inventory with its latest value. PRIVACY Everything stays on your machine in your browser's local storage. There is no account, no sign-in, no backend, no analytics, and no telemetry. The only network request is a same-origin call to steamcommunity.com to read item names for the inventory you are viewing.
