Unfollow Checker

Unfollow Checker is an online tool for reviewing follower relationships on Instagram and Threads using official data exports from Meta. It helps users identify accounts they follow that do not follow them back, see mutual connections, and compare exports from different dates to find followers who are missing or newly added. The service works with ZIP archives containing JSON or HTML data, which users can select without unzipping.

Analysis takes place in the browser, so the archive is not uploaded to the service’s servers, and users never need to provide their Instagram or Threads password. Manual checks and export comparisons are free, require no account, and work in a browser without installing an app. Users can browse or search the resulting lists and may optionally sign in to restore saved export details on another device.

Unfollow Checker also provides step-by-step export instructions, guides, a demo, and FAQ resources. Results are based on available export snapshots and are not definitive proof of an intentional unfollow; any follow or unfollow actions must be completed manually in the official Meta app
