Instagram never tells you. Here's how to find out for free, without logging in — using the data export Instagram already lets you download. It's analysed in your browser, so nothing is uploaded and your account is never touched.
Short version: Instagram doesn't tell you who unfollowed you. There's no notification, no list, and no “recently unfollowed” screen inside the app. That's why so many apps promise to reveal it — and why so many of them cut corners.
Your follower list at any moment is a fact Instagram will hand you: it's in the data export you can request from your own account. Compare the list from two different dates and the people who disappeared are, precisely, the ones who unfollowed you. No guessing, no account access, no scraping.
Follow Crab does exactly that comparison — in your browser. On your first upload it saves a private snapshot of your followers on your device. When you upload a fresh export later, it diffs the two and shows you the exact names.
An export is a snapshot of right now, not a timeline of events. “Who unfollowed you” is a change between two moments, so it fundamentally needs two exports. Any tool claiming to reveal your unfollowers from a single first upload is either fabricating names or counting people who don't follow you back (a different thing). We won't do that — see the safety guide.
Those are available on your very first upload, because they only need one export. Unfollowers arrive on your second.
Not from inside the app — there's no notification or list. But your data export contains your current followers, so comparing two exports over time reveals exactly who unfollowed you. Follow Crab runs that comparison locally in your browser.
No. Instagram sends no unfollow notification and keeps no visible history. Comparing your own exported follower list over time is the only accurate approach.
The safe ones never ask for your Instagram password. Login-based trackers can get your account flagged. Follow Crab never connects to your account at all — it only reads the export you downloaded, and the page can't upload anything. More on safety →
Some do — inflated “unfollows” drive re-opens and ad views. Because Follow Crab diffs your own real export, every name is verifiable against your Instagram data. We can't inflate it.
