About Glimpsr

Glimpsr is a privacy-first Instagram audience analyzer. It shows you who doesn't follow you back, who unfollowed you, your fans, your mutuals, and how your following changes over time — all from the official data export Instagram lets you download.

We built Glimpsr because the existing tools were a trap: to use most unfollower apps you have to type your Instagram password into them — and logging in on your behalf is exactly what breaks Instagram's terms and can get an account banned. Glimpsr takes a different path. Your export is parsed entirely in your browser, and in the default device-only mode your follower data never leaves your device. You can open your browser's network tab and watch — zero bytes are uploaded.

We are an independent team and are not affiliated with, endorsed by, or sponsored by Instagram or Meta. Our promise is simple: no password, ever, and no surprises about what we can see — which is spelled out on what we can see.
