What you get
A self-contained HTML report you can sort, filter and share, plus a CSV for spreadsheets and a JSON file. Everything is built in your browser from what X already shows you when you scroll.
- The list of accounts you follow that do not follow you back, with follower count, following count, posts, join date and bio.
- Your mutuals in a second table, so you can see the whole picture.
- Quick filters such as "10k+ followers", "under 100 followers", "verified" and "joined this year".
- A "Copy handles" button for the rows you are looking at, a CSV for spreadsheets and a share image.
How to run it
Five steps, on a computer. The guided setup on the home page adapts them to your system and username.
Open your following list on X
On a computer, log in to X and open x.com/yourname/following. If the page was already open, reload it right before pasting: the tool reads the list as X loads it.
Open the browser console
Press Cmd+Option+I on a Mac or F12 on Windows and Linux, then click the Console tab.
Copy the script
Use the copy button on this page. The script is plain text you can read; it lives at x-utils.com/dist/non-followers.js.
Paste it in the console and press Enter
The first time, the browser asks you to type "allow pasting" first. Type it, press Enter, paste again.
Wait, then open your report
1 to 3 minutes for a few hundred accounts. Beyond a thousand, X pauses the list now and then; the tool waits and resumes on its own. The report and a CSV land in your Downloads folder.
Why this is safe
The script runs inside the X tab where you are already logged in. It never asks for, reads or stores your password, cookies or keys.
There is no server behind this. The report and the spreadsheet are written straight into your Downloads folder.
No tool follows, unfollows, blocks, likes, posts or deletes anything. It scrolls and takes notes, like a very fast assistant looking at your screen.
The code is open, short, in plain JavaScript and published on GitHub. If you know a developer, ask them to look.
Questions
Does it unfollow anyone?
No. It only reads your following list and writes a report. Unfollowing stays a decision you make yourself, one account at a time, on X.
Why do some rows show less detail than others?
X loads the first screen of the list before the script starts. The tool asks X for that page again; when X refuses, those rows keep only the name and handle.
Can I run it on someone else's account?
Only on a following list you can see. Public accounts work; the report then compares that account's following with its followers as X shows them to you.
