Games on Skinory
Skinory is a free information service for CS2, Dota 2, Rust and TF2: item catalogues, marketplace price comparison and public Steam inventory estimates. Tools, game server lists and data coverage vary by game.
CS2 catalogue and community statistics
Where the data comes from
The CS2 catalogue uses the open CSGO-API dataset. Dota 2, Rust and TF2 catalogues combine Steam data with game item definitions; new pages appear after the relevant catalogue is updated. Prices come from marketplace APIs, storefronts and the Steam Community Market. Refresh intervals vary by source; use the timestamp beside the data.
This product includes GeoLite2 data created by MaxMind.
How we work it out
The price we show
The best buy price across every market we are connected to, rather than a market-wide average. An average would iron out the very thing people come here for — the gap between one market and the next.
Price chart
The recent part is live market prices, one point every 30 minutes. Older history comes from Steam sales, scaled to meet the market level at the point where the two series join: the chart shows how the price moved, not what items actually cost back then.
CS2: Market cap
An analytical estimate by Skinory.io: observed listed value multiplied by an assumed supply coefficient. Skinport is the primary source; Market.CSGO is used only for names without a Skinport price. This is not a measured total value of all existing items.

Who runs the site
Skinory is built and maintained by an independent team of CS2, Dota 2, Rust and TF2 enthusiasts. No legal entity is registered.
Editorial rules
- Pages for items, collections, cases and lists are generated from data: every number in their text comes from the catalogue or the price feeds at the moment the page is rendered.
- Hand-written guides say where their facts come from and show the date of their last update.
- We do not present unofficial numbers as odds: drop pool percentages are labelled as community estimates, because Valve publishes none for the weekly drop.
- Found a mistake? Write to the address below: we check the report against the source and correct the page.

What we do not do
Skinory is not a marketplace: we do not sell or buy items, we do not handle trades, and we do not take payments or deposits. Buy links lead to third-party market websites, and we are not responsible for how they operate or for their terms.
Skinory uses public and authenticated market APIs. Some outgoing links are referrals: we may receive a commission. Price sorting is based on price, regardless of partnerships. The case simulator is free and takes no deposits.
The information here is for reference only and does not constitute investment advice. Prices are volatile and the data comes from external sources — we do not guarantee that it is complete or up to date.
CS2, Dota 2 and Team Fortress 2 belong to Valve; Rust belongs to Facepunch Studios. Names and images belong to their respective rights holders. Skinory is not affiliated with Valve, Steam or Facepunch Studios.
