Counted once we have watched for 90 days (since 21 Oct 2026)

Last 90 days · as of 21:48 UTC

How this is measured

Distinct builds deployed to a game's public (default) Steam branch, as Steam's client network describes them.

Checked within minutes of each Steam change. Observed since 21 Oct 2026.

We see a game's builds only from the day we started watching it. Before that we know just the build it was on, so counts over a window are shown only for games watched for the whole window.
A build is not necessarily a content update: developers also ship fixes, and some builds change only files players never see.
