Can you see who unfollowed you on X?
Not inside X. Its Following FAQ, last updated on 28 September 2026, says X does not send a notification when you unfollow someone, and that rule works both ways: nobody is told when they lose a follower. What X does report is gains. By default it emails you when someone new follows you, and the followers link on your profile shows how many followers you have and who they are. Who left, you have to work out.
A smaller number doesn't always mean an unfollow. The same FAQ says that when accounts are locked, X removes them from follower counts across profiles, so your count can fall when an account that follows you is locked. X's authenticity policy says that when X detects suspicious levels of activity, accounts may be locked and asked for more information, such as a phone number, or to solve a puzzle. A falling count is a weak signal on its own; comparing the lists is a better one.
How do I track followers on Twitter for free?
Compare two copies of your follower list. X's archive help page, updated on 28 September 2026, says your archive includes a list of your followers and a list of the accounts you follow, in HTML and JSON files. Request one today and another in a month.
Request it on desktop
Click the more icon in the navigation bar and choose Your account, then Download an archive of your data. Enter your password and click Confirm. Click Send code to get a code by email or phone, enter it, then click Request data.
Request it on iOS
Tap your profile icon, then Settings and privacy, then Account. Under Data and permissions, tap Your X data. Tap Send code, enter the code, then under Download your data tap Request data next to X.
Request it on Android
Tap the navigation menu icon or your profile icon, then Settings and privacy, then Account. Under Data and permissions, tap Your X data. Tap Send code, enter the code, then under Download your data tap Request data next to X.
Download the .zip
X emails you, or sends a push notification, when the archive is ready, and says preparing it may take a few days. Confirm your email address before you request it, and download it while signed in to X in the same browser.
Inside the zip, the followers file is data/follower.js, according to the documentation of an open-source archive reader written against archives as of 31 August 2023. Each follower appears as an accountId plus a userLink that opens that account. Compare the IDs rather than names, and check your own archive in case the layout has changed.
A worked example, with sample numbers. Priya at Acme, a sample founder account, has 1,240 follower IDs in the 1 October archive and 1,268 in the 1 November one, so the count says +28. The sheet shows 61 new and 33 left: 1,240 - 33 + 61 = 1,268. That is 33 ÷ 1,240 = 2.7% of last month's followers gone, inside a month that looked like growth. Sort the 33 next: three buyers you have spoken to matter more than the other 30.
What do X's rules say about unfollow tracker apps?
X allows third-party apps but puts the responsibility on you. Five rules matter, all checked on 4 November 2026:
- You answer for the apps you connect. X's authenticity policy says that as a user you are ultimately responsible for third-party applications you authorise to access or use your account.
- Access can be broad. X's page on third-party apps says read access can cover the people who follow you and the people you follow, and write access can include following and unfollowing people for you. X strongly recommends reviewing an app's terms and privacy policy before you authorise it.
- Never give an app your password. The same page recommends connecting only through X's OAuth method, which doesn't hand the app your username and password, and warns that whoever has them "can gain complete control of your account". You can revoke any app in the Apps and sessions section of your settings.
- Follower-boosting apps are out. The Following FAQ says apps that promise to get you a lot of followers usually violate X's Terms of Service and may lead to account suspension.
- Scraping needs permission. X's Terms of Service, effective 9 October 2026, say crawling or scraping the Services in any form, for any purpose, without X's prior written consent is expressly prohibited.
Watch what you do with the results, too. The authenticity policy lists follow churn, following and then unfollowing large numbers of accounts to inflate your own follower count, as engagement spam, and also bars using or promoting third-party services to perform any of the transactions it describes. If you unfollow people back, do it one at a time and for a reason. Pruning who you follow for a better feed is a separate job, covered in our guide to resetting your X algorithm.
Which way of tracking unfollowers should you pick?
Pick by how often you need to know and how much access you are willing to give. Prices, limits and descriptions come from each vendor's own pages, checked 4 November 2026.
| Method | Cost | Access it needs | Limits | Best for |
|---|---|---|---|---|
| X archive comparison | Free | None beyond signing in to X yourself | One snapshot per request; X says preparing it may take a few days | A monthly check |
| Circleboom (web app) | Pro plan, account size up to 25,000 followers: $35.99 a month billed monthly, or $23.99 a month billed yearly (23.99 × 12 = $287.88 a year) | You authorise it by signing in with your X account | Who Unfollowed Me works only for accounts with up to 25,000 followers; tracking starts when you connect | Weekly or monthly unfollower emails |
| Browser extension, such as Unfollow Tracker for X (Firefox) | No payment mentioned in its listing | No account or login with the extension; it reads your followers page in your browser | Its listing says it auto-scrolls and scans your followers page and keeps snapshots in browser storage; 24 daily users and one review, rated 1 out of 5, when checked | Local snapshots, once you have read X's scraping clause |
| Any app that asks for your X password | - | Your password | X warns that whoever has it can take complete control | Nothing: don't use one |
Three notes on Circleboom, read from its own pages. Its Who Unfollowed Me page says you can see who unfollowed you for free and set a weekly or monthly email alert, while its pricing page lists Who Unfollowed / Followed Me under the Pro plan, so check which applies before you connect. The same Who Unfollowed Me page offers bulk unfollowing of the accounts it lists, and Circleboom says it is an X Official Enterprise Developer. Its terms of service say subscriptions are billed in advance, are non-refundable for the period purchased and renew automatically unless you cancel from the account dashboard, and that it may collect the email address you log in with for marketing.
The Unfollow Tracker for X listing says no data leaves your device. It also says it works by scanning your followers list on x.com, so read X's scraping clause above before you install it or any extension like it.
Which unfollows matter for a B2B account?
The ones from people you sell to or work with. X's ranking code gives original posts from mutual follows extra weight in For You, through a reply-weight boost. That boost was still set at 15 in the settings file on 4 November 2026. The code that tags mutuals needs both directions: the viewer follows the author and the author follows the viewer. So when a buyer you follow unfollows you, you stop being mutuals and your original posts lose that boost in their feed. Our post on the mutual follow boost explains the mechanics. Thirty strangers leaving matters less than three buyers leaving.
If buyers leave two months running, look at what you post; our guide to growing on X as a B2B founder covers profile and posting basics. If those people are prospects, keep them with the rest of the deal; Siela's built-in CRM holds contacts and companies in a visual pipeline.
Frequently asked questions
Does X tell you when someone unfollows you?
No. X's Following FAQ says it sends no notification when you unfollow someone, which means you get none when someone unfollows you either. X does tell you about new followers: by default it sends an email, which you can turn off in your email preferences. To see losses, compare two snapshots of your follower list taken from your X archive.
Can I see who unfollowed me in the past?
Only from a snapshot you already have. An X archive lists your followers on the day it was made, so an older archive gives you a starting point to compare against. Circleboom's own FAQ says it starts tracking when you connect your account and does not retrieve earlier unfollows. If you have neither, request an archive today and compare it with the next one.
Why did my X follower count drop overnight?
Possible reasons include people unfollowing you, you removing or blocking followers, and accounts that follow you being locked. X's Following FAQ says locked accounts are removed from follower counts across profiles, so your number can fall without anyone choosing to leave. Comparing two archive snapshots shows which accounts are missing, and opening each one shows whether it still exists.
How do I remove a follower on X without blocking them?
On the web, open your followers list, click the more icon to the right of the account's Follow button, choose Remove this follower and confirm with Remove. You can also use the more icon on their profile. X's Following FAQ says this works on the web only for now, and the person can follow you again if your posts are public.
Can an unfollow tracker get my X account suspended?
X's rules focus on what an app does with your account. Its Following FAQ says apps promising lots of followers usually violate its Terms of Service and may lead to suspension, its authenticity policy makes you responsible for apps you authorise, and its terms bar scraping without written consent. Its warnings are sharpest for apps that take your password, which it says can lead to actions that get you suspended.
Can someone see that I unfollowed them on X?
Not through a notification, since X's Following FAQ says it doesn't send one when you unfollow someone. They would find out only by checking their followers list, comparing snapshots or using a tracker app. If they are a buyer you follow, remember that unfollowing also ends any mutual follow between you, and with it the reply boost X's code gives mutuals.
