How to see who unfollowed you on X
The short answer
Install the Futurepost extension and open its Followers tab once. That first load becomes your starting point. From then on, anyone who leaves your follower list appears under Who left, marked as either an unfollow or a deleted account. It is free, and the comparison stays in your browser.
Step by step
- 1
Install the Futurepost extension and open x.com.
Chrome, Edge, Brave and Opera. No account, no password, nothing to authorise.
- 2
Open the panel and click the Followers tab.
It loads your follower list. On a large account this takes a few minutes; leave it running.
- 3
That is your starting point. Nothing else to do today.
The extension keeps a copy. Unfollows from before this moment cannot be recovered, by us or by anyone.
- 4
Come back in a week and open Followers again.
A Who left button appears with a count on it. A week shows you a pattern; a day mostly shows noise.
- 5
Click Check who is still there.
It asks X about each missing account and separates real unfollows from suspended and deleted ones, so a ban does not read as a snub.
- 6
To unfollow them back, use the Left you filter on the Following tab.
It shows the accounts you still follow that stopped following you. Select and unfollow like any other list.
Worth knowing
X removed unfollow notifications years ago and has closed every route to them since. There is no endpoint, no export and no setting. Any service claiming to show who unfollowed you last month is either guessing or listing accounts that disappeared for other reasons.
A missing follower is not always a snub. Suspended accounts, deleted accounts and accounts that went private all vanish from your follower list exactly the way an unfollow does. The check step separates them, which is the difference between a useful list and a grudge generator.
Questions
Can I see who unfollowed me in the past?
No, and neither can any other tool. Tracking only works forward from the day something started recording. Anyone promising historical unfollows is showing you accounts that no longer exist.
Does X notify you when someone unfollows you?
No. No notification, no email, nothing in your activity feed, and that applies to Premium subscribers too.
Why did my follower count drop with no unfollows?
Usually a spam sweep. X removes bot accounts in batches, which can take a visible chunk off a large account overnight. Nobody made a decision about you.
Does my follower list get uploaded anywhere?
Not for this. The comparison runs in your browser and the results stay there.
