Instagram unfollowers Chrome extensions: risks and the safe alternative

How it works

1. 1

   Request the export instead of installing

   In Chrome, open accountscenter.instagram.com (or use the Instagram app) and go to Your information and permissions → Export your information → Create export. Choose Download to device, Followers and following, All time and JSON, and start it.

2. 2

   Download the ZIP

   The email arrives in about 10–20 minutes with a link valid for four days. Click it, confirm your password on Instagram's own screen if asked, and Chrome saves the ZIP to your Downloads folder.

3. 3

   Drop it on unfollow-checker.com

   Open the page in a normal Chrome tab — no extension, no login — and drag the ZIP onto it. The count is free; the full list is a one-time $2.99.

How an unfollowers extension actually works

When you open instagram.com with an unfollowers extension installed, its content script runs on the page with your session cookies attached. To build its list it calls the same internal endpoints Instagram's own front end uses to load your followers, paging through them a few dozen accounts at a time — except a human scrolling takes minutes and the extension takes seconds, firing hundreds of requests back to back. Some do it by literally scrolling your followers dialog in a hidden frame. From Instagram's side there is no visible difference between this and a scraping bot, and the rate limiting responds accordingly — our guide to the Action Blocked message explains the thresholds people have measured.

Behaviour patterns that get accounts flagged

The specific behaviours Instagram reacts to are consistent across extensions:

• Bulk listing at machine speed — the full followers list requested in one burst instead of over a session of scrolling.
• "Unfollow all non-followers" buttons — hundreds of unfollows fired in a minute, which blows through the unfollow limit Instagram enforces per hour and per day.
• Running on every page load — some extensions refresh their counts each time you open instagram.com, repeating the burst daily.
• Phoning home — a number send your username and lists to the developer's server for "sync" or "history" features.
• Scope creep through updates — an extension installed for one feature can gain auto-follow, auto-like or DM features in a later update, under the same permissions.
• We deliberately don't name individual extensions here; the mechanism is shared and the names change every few months.

What Chrome Web Store review does and doesn't check

Every unfollowers extension asks for the permission Chrome describes as Read and change your data on instagram.com. That's a complete description: it can see everything on the page, including your session, and can send requests as you. Web Store review checks that the listing is honest about this and that the code doesn't break Google's policies; it doesn't assess whether using the extension violates Instagram's terms, and it can't see what a developer's server does with data the extension sends out. Extensions are also bought and sold — a well-reviewed one can change owners — and Manifest V3 restricts some remote code but doesn't stop a content script from doing everything described above.

What Instagram sees, and what happens next

The first sign is usually a small sheet saying Action Blocked or We limit how often you can do certain things, which clears after a few hours to a day. Keep going and the blocks lengthen. Alongside that you may get a suspicious login email, a forced password reset, or a Confirm it's you challenge each time you open the app. Repeated automated activity is grounds for disabling the account outright. Users describe all of these in the reports we collected for is it safe to use Instagram unfollow checkers.

The extension-free route in the same browser

You can get the same answer in Chrome without installing anything. Request your export in Accounts Centre, let Chrome download the ZIP, and drop it onto UnfollowChecker — the comparison runs inside that tab without ever touching instagram.com. It works the same in Chrome on Windows or Mac and Chrome on Android. The count and both CSVs are free; the full list of who doesn't follow you back is $2.99 once.

If you've already installed an extension, remove it: type chrome://extensions in the address bar, find it and click Remove. Then change your Instagram password and log out of unfamiliar sessions under Settings → Security → Login activity, since the extension had full access to the session.

What this tool can't do

An extension appears to show live numbers because it's reading your logged-in session; UnfollowChecker can't do that, and it's a feature, not a gap. It shows the account as it stood when Meta generated the export — for a newer answer, request a newer export. It can't unfollow anyone, in bulk or otherwise, and it can't look at any account except the one whose export you upload. Between two exports, the free who unfollowed me comparison shows who left.
