Who doesn't follow back on Instagram / Threads?
Upload your Instagram or Threads data export and instantly see who doesn't follow you back, who unfollowed, and who's new.
Private. We never ask for your password and never see your data — everything is computed right in your browser, nothing leaves your device.
How to get your Instagram file
Open the export: Threads → “Export your information”, or Instagram → Accounts Center → Your information and permissions → Export your information.
Create export → choose a profile → Export to device.
Range — all time, format JSON. Under “Customize information” select only: Following, Threads, Connections → Followers and following. Tap Start export.
The archive arrives by email (one file has both Instagram and Threads). Upload the .zip here — no need to unzip.
See who unfollowed you on Instagram and Threads
Unfollow Checker shows who unfollowed you, who doesn't follow you back, and who's new — for both Instagram and Threads. Upload your official data export and the comparison runs locally in your browser: no password, and nothing is sent to a server.
Instagram doesn't keep an unfollow history, so the tool compares two snapshots to find your unfollowers. You get a clear list of the people who don't follow you back, ready to review and unfollow at your own pace.
No automation, no bots, and no login — your account stays safe. You simply review your Instagram and Threads unfollowers and decide who to unfollow yourself.
How to unfollow from your list
Once your list is ready, just click an account — its profile opens in a new tab and you can unfollow. Watch the short video for an example.
