About Tracker Unfollowers
Compare the followers and following lists in your Instagram export right in your browser. One ZIP shows who doesn’t follow you back. Add a newer ZIP from the same account to see how your follower list changed.
Who builds it
The checker and its guides are published under the Tracker Unfollowers name. It’s an independent project, not affiliated with Instagram or Meta.
Why we built it
An Instagram export gives you the lists, but it doesn’t compare them. We built the checker so you can see the differences without copying usernames into a spreadsheet or connecting another app to your account.
How the checker works
Choose the whole ZIP from your official Instagram data export. The checker finds the followers and following lists inside it, in HTML or JSON format.
- Instagram export
- Read in your browser
- Lists compared
- Recent results saved locally
- One export: Not following back. These are accounts in your following list that aren’t in your followers list. Some may never have followed you.
- Two exports: Changes to your followers. For the same account, the checker compares the earlier and newer followers lists and shows which names appeared or disappeared.
Limits to keep in mind
- This isn’t a live check. Results reflect the lists in your ZIPs. Changes that happen and reverse between exports may not show up.
- A missing name isn’t proof of an unfollow. The Unfollowed tab shows names present in the earlier export but missing in the newer one. An account may have changed its username or become unavailable. The lists don’t show the reason or exact time.
- Use comparable exports. Choose the same account and include the full followers and following lists each time. Incomplete exports can give misleading results.
Your data stays on your device
Your browser opens the ZIP and compares the lists. The checker doesn’t ask for your Instagram password or send us the file or lists. When browser storage is available, the latest two snapshots for each imported account and your stars stay in this browser. Use Clear saved data on the results screen to remove them.
To check what’s sent, open the Network tab in your browser’s developer tools before choosing a ZIP. Page resources may load, but the requests don’t carry your file or follower lists. See the Privacy Policy for details.
Why it's free
The comparison runs on your device, so we don’t need a server to open files or run each check. You can try the sample or check your own ZIP for free.
