See who doesn't follow you back and track unfollows on Instagram and GitHub - entirely on your device. See who doesn't follow you back — and who quietly unfollowed you. Instagram tells you the number. FollowLens tells you the names. It reads the follower and following lists you open, keeps them in your own browser, and from the second scan on shows you exactly what changed. How it works 1. Open a profile — your own, or any whose lists already open for you. 2. Click FollowLens and press Start. The list is opened and walked for you, with a badge on the page showing progress and a Stop button that always works. 3. Save the scan. It becomes your baseline; every scan after it answers the question the platform will not. What you get • Not following back, Unfollowed you, New followers, Mutuals — one click each, every row opens the profile • Follower history chart, per-scan changes, and a date range you can narrow • Compare any two scans side by side, in both directions • Export to CSV, JSON, a printable HTML report, or a full backup that restores on another machine • Several accounts tracked separately, on either platform, each with its own history • An ignore list, for the accounts you would rather stop seeing • 10 languages, light and dark themes, right-to-left support It tells you when a scan is incomplete A platform's own header count can include accounts its list endpoint never returns. A tracker that rounds up produces a wrong "not following back" list and never admits it. FollowLens shows what it collected against what was expected, and will not call a list complete when it knows it is not. Privacy There is no server to send anything to. No account, no sign-in, no analytics, no telemetry. Your scans live in your browser's own database and are deleted when you delete them. FollowLens never posts, follows, unfollows or messages anyone on your behalf — it only reads, and only what you can already see. Free and open source, MIT licensed. Every line is on GitHub.
