Client‑side Instagram follow‑back checker, no login needed
The tool lets Instagram users upload their official data export and instantly see who they follow that doesn't follow back, who are mutuals, and who are fans. It runs entirely in the browser, so no credentials, scraping, or server are involved, keeping personal data private. Users can search, mark accounts as kept or unfollowed, and export CSVs for further action. This client‑only approach offers a safer alternative to existing scraping‑based utilities.
