Who Unfollowed Me on Twitter? A Privacy-First Unfollower Detector
Every unfollower tool on the market wants your Twitter password. Ours never asks — it runs inside your browser, stores snapshots locally, and tells you exactly who dropped you.
Search "who unfollowed me on Twitter" and you'll get a dozen web apps asking you to hand over your account. Some ask for your password directly (never do that), most ask for a full OAuth scope that lets them post, DM, and follow on your behalf. All of them store your follower list on someone else's server.
We thought that was silly. You're already logged into Twitter in your browser — why would you need to give a stranger your credentials to answer a question your browser can already answer itself? So we built the unfollower detector as a Chrome extension that runs entirely on your machine.
How the local-first model works
When you open the extension, it uses the same API your Twitter tab uses — logged in as you, authenticated via your existing session cookie, zero credentials transferred anywhere. It fetches your current following list and saves it as a snapshot in your browser's local storage. That snapshot never leaves your machine.
Run it again next week and the extension compares the new list against the last snapshot. Anyone who was in the old list but missing from the new one is an unfollower. That's the whole algorithm.
What you actually see
The results page shows each unfollower with:
- Handle and display name
- Profile picture (fetched fresh, not stored)
- X Premium badge status
- Whether they were a mutual follow before the drop (the painful ones)
- Detected on date — roughly when the unfollow happened, based on snapshot timing
Why "mutual" matters
Losing a follower who never followed you back is noise — they probably did a cleanup round. Losing a mutual is a signal. It means a peer who was actively reading you decided to stop. That's worth paying attention to — not to beg them back, but to notice patterns. Did you change topics? Did you post something divisive? The mutual-only filter in the detector is where the real feedback lives.
What we explicitly don't do
- No password input, ever — we use your existing session
- No OAuth "post on your behalf" scopes
- No server-side storage of follower lists
- No social features, no leaderboards of "most unfollowed", no public data at all
- No auto-unfollow the people who unfollowed you — that's petty automation we refuse to ship
Exporting the data
If you want to keep a longer history than the extension holds, there's a one-click export to CSV. You own the data, it lives in your Downloads folder, and the extension doesn't phone home about it. If you uninstall the extension, everything it ever saw disappears with it.
Install and forget
Most people run a snapshot once a week, scan the diff in under 30 seconds, and close the tab. That's the entire intended workflow. We don't want you obsessing over follower count — we want you to have a quick, honest answer to a question that would otherwise require handing your account to a random website.
