| Open source tool to analyze Instagram followers/following. Zero server-side data: all processing happens in your browser (localStorage). What it does: - Upload Instagram JSON exports - See who doesn't follow you back and vice versa - Track trends over time with multiple snapshots - Export/backup your data Stack: Next.js 15 + TypeScript + shadcn/ui + Recharts Why I built it: Instagram doesn't give visibility into this data and existing apps always require account access or send data to their servers. This is fully client-side. Limitations: - Manual Instagram data export required each time - I have few followers, so haven't tested with large datasets (10k+ followers). would appreciate feedback on performance if you try it Open to feedback on UX and missing features |
