After getting frustrated with Instagram analytics apps that require account access or send data to their servers or are not free I built InstaTrack: a fully client-side tool to analyze followers/following.
What it does:
- Upload Instagram JSON exports (followers/following)
- See who doesn't follow you back and vice versa
- Track trends over time with multiple snapshots
All processing happens in your browser (localStorage), zero server involvement
Try it: https://instatrack.njoylab.com
GitHub: https://github.com/njoylab/instatrack
I have few followers, so haven't tested performance with large datasets (10k+ followers). If anyone tries it with a big following, would love feedback on how it handles.
Open to any feedback on UX or features!
