Privacy

Nothing leaves your browser. Truly.

No Login

We never ask for your password. Instagram never sees us at all.

No Server

Everything runs in your browser. There is no backend to leak data from.

No Tracking

No analytics, no cookies, no fingerprinting. Open the network tab and check.

Open Source

The bookmarklet is a few hundred lines of JavaScript. Read it before you run it.

Questions

Things people ask.

Is this safe?

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.

Will Instagram ban me for using this?

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.

It stopped halfway through. What happened?

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.

Why is there a 10,000 follower cap?

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.

Does this work on private accounts?

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.

What about the official Instagram data export?

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.
