Works directly with the JSON files from Instagram's official data download. No file conversion needed — just upload followers_1.json and following.json and get instant results.

Built with Next.js and deployed as a static site on Netlify. The analysis engine runs entirely in your browser's JavaScript runtime, not on any remote server.

Unlike other tools, FollowerLost never asks for your Instagram username or password. You simply upload the data export files you downloaded from Instagram yourself.

Analysis happens in milliseconds. Upload your files and see results immediately — no waiting, no processing queues, no loading screens.
