Our Mission
UnfollowerSpy exists to give people transparency over their Instagram following in a way that is private, simple, and free. Social media relationships are often opaque by design. We built a tool that gives users a direct answer without asking them to trust another service with their account credentials.
How It Works
Upload your data file
Download your Instagram export and upload the zip file directly into the tool.
We analyse it in your browser
The file is processed locally on your device rather than sent to our servers.
See who does not follow you back
The tool compares your followers and following lists and shows the difference clearly.
Why We Built This
Instagram used to make follower relationships feel simpler. Over time, the product moved away from giving people an easy, direct way to see who had unfollowed them or who never followed back in the first place. That gap created a wave of risky third-party apps asking for Instagram logins and broad permissions.
We did not think that tradeoff was acceptable. People should not have to hand over their account credentials just to get a basic answer about their own network. So we built a free, private alternative that requires no login and stores nothing.
Privacy First
Your Instagram data does not leave the browser while the audit runs. No Instagram login is required. No follower lists are stored on our servers. The product is intentionally built around local processing so you can use it without giving up control of your account data.
Contact & Feedback
If you have a bug report, suggestion, or feedback about how the tool should improve, send a note. We read product feedback closely because the best version of this site is the one that stays useful without becoming invasive.
