instrack.dev is a free, browser-based Instagram follower tracker. We built it because every other option wanted something first — a password, an app install, or a free trial that quietly turned into a subscription.

We don’t store passwords, we don’t ask for access to your Instagram session, and we don’t try to be a full social analytics suite. The tool answers one question well: what changed about a public account’s followers, and when?

Instagram Follower Tracker is not affiliated with, endorsed by, or sponsored by Instagram or Meta. All data shown is drawn from publicly available profile information at the time of lookup.
