SteamDB

Use an application page when you need to inspect Steam-related information rather than download a game. The FAQ is worth reading before interpreting player counts or account calculations, because it explains how the site gathers and displays those figures. SteamDB is an independent informational resource, not Valve’s customer support or a source of game licenses.

For price history, search for the title and open its Prices tab. For sharing restrictions, inspect the Information table for the family-sharing exclusion field. SteamDB notes that account game counts can differ from Steam because the underlying API treats some games and DLC differently.
