About X Unfollowers
Checking who doesn't follow you back on X used to be a solved problem — half a dozen apps did it through the free API, and then the free API stopped being free. What replaced it is a field of sites that want you to “Connect with X” and authorize an app that can also read your DMs, post on your behalf and follow accounts for you, all to answer a question that is really just set subtraction. This tool does the subtraction and nothing else. You bring two lists of handles, it tells you which names appear in one and not the other, and the whole thing happens in the tab you're looking at. Nothing is authorized, nothing is uploaded, and no token of yours ever exists.
How to use it
- 1Open your own profile on x.com and click Following. Scroll to load the names you care about, select the visible handles, and copy them — then do the same on your Followers page. Screen-reader users and keyboard users can select-all within the list container; the parser ignores everything that isn't handle-shaped, so extra text like bios and “Follows you” badges is harmless.
- 2Paste the followers into the left box and the accounts you follow into the right one, one per line. Plain names, @handles and full x.com links all work, and duplicates are collapsed automatically.
- 3Hit “Check non-followers”. The first tab is everyone you follow who doesn't follow you back; copy the whole list in one click, or open any profile to check it before you act.
Why use it
FAQ
Why can't I just upload my X data archive?
Because it doesn't contain what's needed. X's archive stores follower.js and following.js as lists of numeric account IDs with no usernames attached, so there's nothing readable to compare. If you drop those files in anyway, the tool tells you exactly that instead of showing an empty result. Pasting the handles is the working path.
Do I have to connect my X account?
No. There is no OAuth button on this page, by design. Any unfollowers site that asks you to authorize an app is requesting far more permission than a comparison needs — usually including the ability to follow and unfollow on your behalf.
I follow thousands of accounts. Do I have to scroll all of them?
For a complete answer, yes — X only renders what you've scrolled past. Most people don't need complete: scroll back as far as you actually care about, and the comparison is accurate for everything you loaded.
Does it matter if a handle's capitalization differs between the two lists?
No. X handles are case-insensitive, and so is the comparison — @Handle and @handle are treated as the same account, which stops one name from appearing in two contradictory tabs.
Will it unfollow anyone for me?
Never. It produces a list and links out to profiles. Bulk-unfollow automation is what gets accounts limited, and it isn't something you should hand to any website.
Is my list stored anywhere?
No. Everything is compared in your browser's memory — there's no upload, no account, and no logging of the handles you paste. Close the tab and it's gone.
