Instant Sell

One place to compare sell routes

SkinAlyze can already read prices from some sites directly. The extension adds the sites that only work when you are logged in through your browser. It does not sell anything for you. It just shows the numbers so you can decide.

Instant Sell

Check prices from marketplaces you already use, then send the best cash and trade-credit quotes back to SkinAlyze.

Steam stays up to date

Your inventory, trade offers, and market history can refresh from your own Steam login.

Works with Listing Helper

Fresh quotes show up where you already decide where to list, sell, or wait.

You control permissions

Marketplace access is only requested when needed, and you can manage it from the extension popup.

Versions

Chrome and Firefox have the full extension. GitHub is for source review.

Install the official build for your browser. GitHub lets people inspect the public Steam sync component, but it does not mean every SkinAlyze feature is open source.
