Instacleanser

InstaCleanser helps you understand your Instagram followers and following without handing your password to another website. You stay logged in on instagram.com in a normal tab; the extension runs analysis in that same browser session.

What you can do
- Run a full compare and see Followers, Following, and people you follow who don’t follow you back.
- On your own profile, unfollow one account at a time or use Unfollow all (use responsibly—Instagram may rate-limit you).
- On someone else’s username, lists are read-only so you don’t change your following by mistake.
- Optional side panel (Chrome 114+) keeps the UI open while you switch tabs. Your last successful run is saved locally in Chrome storage and restored when you reopen the popup or panel.

Requirements
- Chromium-based browser (Chrome or Edge).
- Stay logged in on instagram.com in the tab you use for analysis.

Instagram does not ship a public API for this workflow.

The extension relies on the same kind of requests the website uses; behavior can change. Unfollow at your own risk and pace.
