Your CS2 inventory, on the books.
LootSpectrum reads your Steam inventory history through a browser extension and turns every case, trade-up and drop into a ledger you can actually read: what you pulled, what it cost, and what it is worth today.

New cases and collections, priced every day.
Every item Valve ships lands in the catalog with its contents, float ranges and prices from Steam, Skinport and CSFloat. Free to browse, no account needed.
Newest cases
All cases
Every case you ever cracked, audited.
Openings by year, rarity distribution against Valve's official odds, streaks, best pulls, and the number nobody likes to look at: what it all cost versus what it is worth. Spoiler: it is usually red. We show it anyway.
Streaks and cadence
Weekly drop streaks, opening sprees and quiet months: the rhythm of your account, back to your first case.
Financials you can stand behind
Cost at the time of opening against today's market value, per case and in aggregate, with ROI that includes the key.
Luck, quantified
Your rarity distribution compared with the official odds, so you know whether that Covert drought is bad luck or just math.
One ledger for everything that touched your inventory.
Openings, trade-ups, drops and current holdings live in the same place.
- 01
Inventory value, day by day
Every skin you hold, priced across Steam, Skinport and CSFloat, with a 30-day trend per item and the option to rewind to any past snapshot.

Luck tracker
Your rarity distribution laid over the official odds, per case and overall. Finally an answer to “am I cursed?”.

Watchlist and compare
Pin items you are eyeing, compare price matrices and float ranges side by side, and see how each market prices the same skin.

Loadout builder
Plan a full loadout from the catalog and price it before you spend a cent. Save it and revisit when the market moves.

The whole catalog
Every case with its contents, every collection, every skin with float spectrum, variants, price history and market comparison.
Browse items
Three steps, no manual entry, ever.
Steam already keeps the receipts. LootSpectrum just reads them. You never type in a case or paste an inspect link.
- 01
Install the extension
Add LootSpectrum to Chrome or Firefox and sign in. The extension only ever reads the inventory history page you can already see on Steam.
- 02
Sync your history
Pick catch-up, full or a custom date range. The extension walks your Steam history page by page, pauses for rate limits on its own and uploads in batches.
- 03
Read the ledger
Statistics, inventory value and event history fill in as the first batch lands. Most accounts finish a full sync in ten to fifteen minutes.

Read the how-to
- Is my Steam account safe?
- Yes. The extension reads the inventory history page you can already see while logged into Steam. It never receives your credentials, never trades and never changes anything on your account.
- Which browsers are supported?
- Chrome and Firefox are fully supported. Chromium-based browsers such as Edge and Brave work with the Chrome extension.
- How long does a sync take?
- Steam rate-limits its history pages, so a full sync of an average account takes ten to fifteen minutes. Heavy traders take longer; the extension pauses and resumes on its own.
- What about openings from before I installed it?
- A full sync walks your entire Steam inventory history, so every case, drop and trade-up since your first one shows up in your statistics.
- Does it cost anything?
- Sync, storage, event history, basic statistics and current holdings are free. Financial statistics, historical valuation, long-range market history, priced exports and higher limits are supporter features.
- Can I delete my data?
- Yes. Clear Data on the Sync page removes every synced event from our servers; you can run a fresh sync at any time afterwards.
Your next unboxing deserves better than a screenshot.
Give every pull, drop and trade-up a line in the ledger. Syncing is free and takes about as long as a coffee.
