Log "buys & sells" and visualizes your crypto portfolio

A single page, offline friendly crypto portfolio tracker built with vanilla HTML/CSS/JS. It lets you log buys and sells, computes average cost, tracks realized/unrealized P&L, and visualizes your portfolio. Live pricing comes from the public CoinPaprika API; all data stays in the browser and its PWA :)
Hey Product Hunt!
This is my first product launch on PH! I have always wanted to publish something, so here is my try :)
I built Crypto Investment Tracker so I can keep my own crypto data entirely local, no accounts, no cloud and decided to make it public for anyone to download and run themselves (github) or use via browser.
- Log buys/sells with fees, notes, and timestamps.
- Live USD prices from CoinPaprika; falls back to last trade price if offline.
- Portfolio metrics plus 7 Chart.js views: allocation, value vs invested, unrealized/realized P&L, holdings over time, cost vs value, buy/sell volume, ROI by coin.
- Data lives in your browser (localStorage), with CSV export and backup/restore JSON.
- Offline-ready PWA (service worker + manifest) after first load.
I’d love feedback on:
- Which chart is most useful (or missing)?
- What would make it trustworthy for daily use?
- Any rough edges in onboarding or data entry?
Thanks for checking it out! 🚀
