Do I need to sign in to check an inventory?
No. Enter any Steam ID, profile URL, or vanity name and SboxCharts prices the whole public s&box inventory at live market value — yours or anyone else's. Signing in with Steam is optional and only adds a saved portfolio with daily value history.
What does signing in add?
Sign in with your Steam account — we never see your password. SboxCharts then syncs your s&box inventory from Steam, prices every item using the latest market data, and snapshots your portfolio value daily so you can track changes over time.
Is my data safe?
