What is LootSpectrum and what does it track?

Step by step

1. Steam keeps a history of everything that entered or left your CS2 inventory.
2. The LootSpectrum browser extension reads that history in your own browser, while you are signed in to Steam; it never asks for your Steam password.
3. LootSpectrum sorts it into events and lists them in Activity with the badges “Opening”, “Trade-up” and “Drop”, among others.
4. Your current inventory is listed in Inventory with a name and a count for every item.
5. To start: create an account, install the extension, then run your first full sync.

Good to know

• These events are recognised: openings of cases, souvenir packages and capsules, trade-ups, drops, Armory redemptions, and market and storage moves.
• Only CS2 and CS:GO history is read. Other games are ignored.
• LootSpectrum can only show what Steam's own inventory history page shows.
• The extension works in Chrome, Firefox and Chromium browsers such as Brave and Edge.
• Syncing, the full event history, counts and the total value of your inventory at Steam prices are free. The value of each item, and what your openings cost and returned, are Supporter figures; on a free account they show as a hatched bar.
