How to See Who Unfollowed You on X (X Won't Tell You)

Your follower count is lower than last week and X said nothing about it. Working out how to see who unfollowed you on Twitter — X, formerly Twitter — comes down to a single mechanic, and every tracker on the first page of Google runs on it: snapshot your followers now, snapshot them later, subtract. See that, and you can run it yourself or judge a tool honestly before connecting it.

Does X Tell You When Someone Unfollows? (No — and It Keeps No History)

No. X notifies you when someone follows you. When they leave, nothing happens: no push, no email, no line in your notifications tab. Don't take our word for it — open Settings → Notifications → Preferences and look for an unfollow toggle. There isn't one to switch on.

There's no record after the fact either. X keeps your current followers list, not the change log behind it. So the answer is two-part: not from anything X shows you, and not retroactively from anywhere else. Nothing can reconstruct who left last month unless something was already watching last month — which is load-bearing for everything below.

The one case that needs no tool at all

If you already suspect a specific person, open their profile. When an account follows you, X shows a small Follows you badge next to their handle; if the badge is gone and you remember it being there, they aren't following you any more — though a suspension or a block reads the same way. That check takes seconds.

How Unfollow Trackers Actually Work: Two Snapshots, One Diff

Every tracker — browser extension, web app, "free unfollowers checker" — does the same three things:

1. Read your followers list and store it.
2. Read it again later, on a schedule.
3. Subtract. Anyone in the old list but not the new one gets labelled an unfollower.

X's API does emit unfollow events — the Activity API fires follow.unfollow — but each account you want watched needs its own paid subscription slot, and every tier caps how many. A tracker's customer base has to fit that cap, so consumer trackers poll instead: hourly, daily, whatever their pricing supports.

Two consequences:

• Your history starts the day the tool starts. On day one it holds one snapshot and nothing to compare it to.
• A diff sees departures, not reasons. A suspended bot, a deleted account and a real person who got bored look identical in the subtraction.

How to See Who Unfollowed You on Twitter by Hand, Without Giving Anyone Access

1. On desktop, open your own profile and click Followers.
2. Scroll in chunks, copying as you go — a select-all at the end can miss rows.
3. Paste into a plain text file dated today — followers-2026-09-08.txt — and keep only the @handle lines. Display names and bios change; handles don't, so the diff stays clean.
4. Repeat in a week or two into a second dated file.
5. Compare the two.

On macOS or Linux, the comparison is one line:

comm -23 <(sort followers-2026-09-08.txt) <(sort followers-2026-09-22.txt)

Anything it prints was in the old list and isn't in the new one. Without a terminal, paste each list into its own spreadsheet column and use a lookup — same subtraction.

It has two limits worth saying out loud: it's comfortable at a few hundred or a few thousand followers and a chore beyond that, and it only works forward. Your first file is your zero point, exactly like a tracker's.

What about your X data archive? Settings → Your account → Download an archive of your data sends a zip containing follower and following files — but they hold numeric account IDs, not handles, as community documentation of the archive format has flagged for years. Resolving every ID to a name is slower than copying the list off the page — which also arrives now, not days later.

What Access a Tracker Asks For — and What That Means

If the manual route isn't for you, know what you're trading. Two shapes:

An OAuth connection. You sign in with X and approve a permission screen; the app then reads your follower list on its own schedule, while you're asleep. Read that screen instead of clicking through it. Reading your followers is one thing; posting, following and unfollowing on your behalf is another, and some of these tools ask for both, because the same product also sells bulk unfollowing.

A browser extension. It runs inside your logged-in session on x.com — no permission screen, no server-side connection, but it reads whatever that session can, and updates itself whenever the developer ships.

Whichever shape you pick:

• Never type your X password anywhere but x.com, and never paste session cookies into a website. A legitimate tracker needs neither.
• Know how to revoke before you grant. Settings → Security and account access → Apps and sessions → Connected apps.
• Distrust instant history. Any tool offering "everyone who unfollowed you this year" the moment you connect cannot have that data — the diff needs a first snapshot, and yours doesn't exist yet.

We won't name a tracker to install. The trade is standing access to your account for a list of names, and only you know what that's worth.

Why Your Follower Count Dropped When Nobody Unfollowed

Before you hunt for names: a falling count often has nothing to do with anyone choosing to leave.

X removes accounts in waves. During an April 2026 sweep, head of product Nikita Bier said the platform was suspending 208 bots per minute, and creators lost thousands of followers within days while it ran. Nobody unfollowed them — the accounts were deleted out from under the count. Same for anyone who deactivates, gets suspended or deletes: they leave your followers list exactly the way an unfollow does.

There's plain lag too: when the number on your profile and the length of your actual list disagree, trust the list.

This is where a diff misleads. A tracker hands you fifty "unfollowers", you read it as a verdict on last month's posting, and half those handles no longer resolve. Click a few before drawing conclusions about your content.

Start cleaning up your X account with Postory

First, what we don't do: Postory doesn't track unfollows. No follower monitoring, no unfollow alerts, nothing sitting on your followers list. Unfollows you can't see — dead accounts you follow, you can, and the cleaner names them.

That's the other list, the one you control. Postory's Following Cleaner reads the accounts you follow and names the dormant, the deleted and the ones that never post. No sign-up, no connected account, from $4.99. The unfollowing happens on X, by you — the cleaner never asks to touch your following list.

Tidying the other direction? Here's the step-by-step for removing followers on X.
