Glasscase values your Steam inventory: live floor, average sales, and payouts

⚡ The gist in 5 seconds

• Glasscase values your entire Steam inventory: live floor, averages based on real sales over 24 h / 7 / 30 / 90 days, and net payout after each marketplace's fees.
• One portable build — .exe or AppImage, data stored next to the file, no account required, no telemetry (per the README).
• Steam wallet and cash are kept separate, but for full sales history you're asked to paste your steamLoginSecure cookie.

🔍 What happened

A repository called MythicHokageRepel/steam-inventory-value-desktop has been published on GitHub — a desktop Steam inventory valuator. The README names the app Glasscase. The root contains src, build, scripts, test, package.json and package-lock.json; judging by that set, I'd bet on a Node stack, but that's my guess, not a line from the documentation. The entire repository history is 2 commits.

The mechanics come down to three metrics. LOWEST — the cheapest live listing, by default the Steam Community Market floor via priceoverview, with a fallback to Skinport. AVG — the average based on real Skinport sales (7 days by default), with a switch to Steam sales. NET and Instant — what lands in your wallet when listing at the floor, and what buy orders would pay right now, walked through the order book for your quantity. The floors of Steam, Skinport, Waxpeer, Market.CSGO and Lis-skins sit side by side: net after each one's fee, "where it's cheaper to buy," "where it's more profitable to sell." Next to each average are the median and the largest sale; skewed averages are flagged, and a trimmed average can be enabled via an option and is always labeled. Items without a price are counted, not zeroed out; non-marketable items are excluded from the total.

🧠 Our take

The CS2 skin market has long lived outside Steam: Skinport, Market.CSGO, Lis-skins and Waxpeer took a share of trades precisely because Steam pays sellers in wallet funds, not money. Tools that say "your inventory is worth $X" answer the wrong question. Here the key number isn't "what it's worth" but "what you can cash out." Our assessment: this is the real gap in the market — not price, but liquidity.

What this changes for someone with a hundred items: the gap between the floor and the actual exit price can be multiples apart. The app walks the order book for your quantity and separately shows how much would sell within a week — in our experience, it's that figure, not the pretty total, that determines whether a sell-off is worth doing at all. Keeping cash and wallet funds separate, with every source labeled by window and marketplace, is the right default that you rarely see in simpler trackers.

The winners are low-fee marketplaces: they're now visible in one window next to Steam. The losers are those used to measuring a collection with a single number from the client. And, honestly, the project itself: two commits and a README signed with a different name than the repository title — not the kind of profile I'd hand a session cookie to without questions.

⚠️ What we don't know

The source has no version number, no release date, and not a single independent review or build verification — just the README and the repository files. The promise of "no accounts and no telemetry" sits alongside an option to paste steamLoginSecure, and while that's not a contradiction, I wouldn't recommend testing it on your own account: the cookie grants session access. A portable .exe from an account with no history and two commits is a risk the README doesn't remove; at minimum, verify the build hash and run it in a sandbox.

Prediction: by the end of the quarter, the repository will either get a release tag and at least one independent build review, or it will remain at two commits. I'm betting on the latter.

Disclaimer: not officially confirmed — a single source, the repository README; no independent build verification exists.
