Free Steam Deals Monitor is a website that tracks Steam games temporarily available at a 100% discount, helping players spot titles they can claim for free while an offer is active. Visitors can browse recently found deals and sort the listings by discovery time, original price, or game name. The site also includes a Steam Library Value calculator, which estimates the current storefront value of the visible games in a public Steam profile.

To use it, visitors provide a profile link and select a pricing region, with options including Germany, the United States, Russia, Kazakhstan, Turkey, and Ukraine. The site explains how to find a profile URL, check that the profile and game details are public, and copy a suitable link. No Steam sign-in is required on the website.

The calculator reports an estimated current retail value, not the amount a user actually spent on purchases. Free Steam Deals Monitor states that it is not affiliated with Valve or Steam
