Follower Analyzer: Unfollowers & Fans

Find out who doesn't follow you back on Instagram — right in your browser. Nothing is uploaded; everything is processed on your own device. Upload your official Instagram data export (the "followers" and "following" JSON files) and instantly see: • Not following back — accounts you follow that don't follow you • Fans — accounts that follow you that you don't follow back • Mutuals, plus how long ago you followed each account • Who unfollowed you since your last upload (snapshot comparison) Then, using your own logged-in Instagram session, you can optionally check whether those accounts are still Active, Private, or Deactivated — a check that only works from inside your real browser. More tools: • Search, sort, and filter your lists • Ignore accounts you follow on purpose (brands, celebrities) so they stop appearing • Export any list to CSV or JSON Privacy first: • 100% on-device — your files, results, and settings never leave your browser • No account, no server, no analytics, no tracking • It never sees your password — it uses your existing browser session only How to use: 1. Log in to instagram.com in the same browser 2. Click the extension icon to open its page 3. Upload followers_*.json and following.json from your Instagram data download 4. Review the results and, if you like, check account statuses Get your data from Instagram: Settings → Accounts Center → Your information and permissions → Download your information → choose "Followers and following" in JSON format.
