See who an account follows — and what changed.
Scan an Instagram account's following list, then come back later to see exactly who they started and stopped following. Runs entirely in your browser with your own session — nothing is ever sent to a server.

Three ways to run it
Chrome extension
The full experience: a dockable side panel, automatic snapshots per account, and history. Load it unpacked (free, no store account needed).
- Unzip it.
- Open chrome://extensions and turn on Developer mode.
- Click Load unpacked and select the folder.
Bookmarklet
Zero install. Drag this button to your bookmarks bar, then click it on instagram.com to open the panel.
Drag ↑ to your bookmarks bar. Desktop Chrome / Firefox / Edge.
Console script
For the paste-it-yourself crowd. Copy the script, open DevTools on instagram.com, paste it into the Console, and hit Enter.
Same panel, no bookmark needed. Tiny and fully readable in the repo.
Snapshot, then diff
Scan an account
Enter a username. It pages through their following list from your logged-in session, with human-like pacing to avoid rate limits.
It saves a snapshot
The list is stored locally (or exported as JSON). That becomes your baseline for next time.
See what changed
Scan again later and it diffs against the snapshot — a clean list of who was added and who was dropped, matched by account id so renames don't lie.
Your data never leaves your browser
There is no backend. Every request uses your own Instagram session, and every snapshot is stored locally on your machine. No accounts, no tracking, no server. Read the source — it's all here.
