Instagram Unfollow TrackerTrack Followers on Demand

Detection is scan-based. Your first scan saves a snapshot of your public follower list, and each later scan is checked against the earlier list — anyone missing from the new snapshot shows up as an unfollower. Changes are detected at the next scan you run, and your history starts from your first scan.

No — never. You only enter a public @username. We don't log in to your account, we don't connect to it, and there is no password field anywhere in the product.

Yes. That's the core of how the tool works: enter your public username and the scan reads your public follower list — no Instagram login and no connected account. You only sign in to FollowRoster itself if you want to save your scan history or subscribe.

It's free to start. You can enter a username and preview results without creating an account, and a free account adds basic analytics and saved scan history. Paid plans unlock the complete lists, tracking for multiple accounts, and data exports.

Yes — and unlike unfollow detection, this works from a single scan. We match your follower list against your following list and show every account that doesn't follow you back, plus the fans who follow you without a follow back.

No. Scans are anonymous and read only public information. The account you check receives no notification, and nothing changes on your Instagram profile.

Because there's nothing to measure against yet. The first scan is your baseline; unfollowers appear from your second scan onward, based on what changed between the two snapshots. You can still see who doesn't follow you back right away.

A scan can only read lists that are publicly visible, so private accounts can't be analyzed. If your profile is private, you'd need to switch it to public while the scan runs.
