Following Tracker
Open source · local only

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).

Download .zip
  1. Unzip it.
  2. Open chrome://extensions and turn on Developer mode.
  3. 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.

Following Tracker

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.

How it works

Snapshot, then diff

01

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.

02

It saves a snapshot

The list is stored locally (or exported as JSON). That becomes your baseline for next time.

03

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.
