Scan your Instagram and instantly see who doesn't follow you back. One click. No login. No server.
Get StartedSee who doesn't follow you back.
We scan your Instagram securely and instantly.
Clean up your network and focus on real ones.
We never post. We never share. We just analyze.
Add our tool to your bookmarks bar in one click.
Go to instagram.com and make sure you're logged in.
Click the bookmarklet. We'll scan and bring you back with results.
Drag this button to your bookmarks bar. That's it.
Don't see your bookmarks bar? Press ⌘⇧B on Mac or Ctrl+Shift+B on Windows.
We never ask for your password. Instagram never sees us at all.
Everything runs in your browser. There is no backend to leak data from.
No analytics, no cookies, no fingerprinting. Open the network tab and check.
The bookmarklet is a few hundred lines of JavaScript. Read it before you run it.
Yes. The bookmarklet is JavaScript that runs in your own browser, on your own logged-in Instagram session, the same way the Instagram website does. It doesn't send your data anywhere except back to Flock, in your URL bar, where you can see it.
We don't think so, but we can't promise. The bookmarklet makes the same requests Instagram's own web app makes, and it deliberately goes slowly to look like a real person browsing. If Instagram throttles you, you might be temporarily blocked from viewing follower lists for half an hour. We don't know of anyone whose account has been banned for using a tool like this, but tools like this exist in a gray area.
Instagram throttled the requests. This is normal on big accounts. Wait about 30 minutes, then click the bookmarklet again on Instagram -- it remembers where it left off and picks up from there. We saved your progress.
Above 10k, the scan takes long enough that Instagram is much more likely to throttle you. If you really need it for a bigger account, the code is open source -- fork it and remove the cap.
Yes, for your own account and any private account you already follow. The bookmarklet uses your own logged-in session, so it sees exactly what you see when you're scrolling Instagram normally.
That still works and is more reliable, but it's slow (Instagram emails it to you, can take a day) and the file format keeps changing. The bookmarklet is the fast version.
Everyone's got your back. Nothing to see here.
