See who you follow that doesn't follow back — from your own Instagram data.
Nothing leaves your browser. Your files are read and compared on this page only. Nothing is uploaded, stored, or sent anywhere — close the tab and it's gone.
Onesided compares your Instagram following.json and followers_1.json export files
entirely in your browser to show you who doesn't follow you back, your mutual follows, your admirers,
and — if you add an older followers snapshot — who has unfollowed you since. No account, no upload,
no data ever leaves your device.
