Check CS2 skin prices without leaving Steam: a small panel on Market listings and inventories compares marketplace prices and links the item on SkinSniper.

What it does

Open a CS2 item on Steam and the panel lists its price on 11 marketplaces, sorted from cheapest, each with its difference vs the Steam price.

Market listings

Prices for the exact skin and condition on the page. Works on the classic market layout and the new Market Beta, following the exterior and StatTrak filters you pick.

Inventories

Click an item in any public Steam inventory to see its prices. The panel also links the inventory value calculator for that profile.

Toolbar popup

Search the CS2 skin catalog, see the item from the current tab and open the trade-up and price comparison tools.

Difference vs Steam

Each marketplace row carries a badge with how much cheaper or pricier it is than the Steam listing.

Your currency and language

If you use skinsniper.com, the panel shows prices in the currency and language you picked there.

Stays out of the way

Drag the panel anywhere, pick its corner in the popup, or collapse it to a small logo until you need it.

Privacy and permissions

  • No requests to Steam servers: item names are read from the page you already have open, prices come from the SkinSniper API. On an inventory page it also reads the profile id from the URL, only so the inventory value calculator points at that inventory.
  • Two manifest permissions (cookies and storage) plus site access to steamcommunity.com and skinsniper.com, which is what the install prompt asks about. The cookies permission covers skinsniper.com only, your currency and language, and cannot reach Steam cookies.
  • No analytics, no telemetry, no account required. One job: prices - no selling tools, no trade automation, no buttons injected all over Steam.
  • Open source under the MIT license - the full code is public on GitHub.
