Open-source stock investment portfolio tracker. No authentication, no database, no account required. Track buy/sell transactions, live prices, IRR, CAGR, Sharpe ratio, and portfolio allocation in your browser.

Hey everyone! 👋 I'm Miguel, and I've been investing in stocks for over 7 years now. For all that time, my tracking tool was… Google Sheets. It worked, but let's be honest — it was clunky, fragile, and computing proper metrics like IRR or Sharpe ratio was a nightmare of nested formulas. This weekend I finally decided to build what I always wished existed: a proper portfolio tracker that's free, open source, and doesn't require you to create an account or hand over your financial data. OpenStocky runs entirely in your browser. No database, no backend storage, no sign-up. You add your buy/sell transactions (one by one or by pasting CSV from Excel), and you instantly get: 📊 Advanced metrics — IRR, CAGR, Sharpe ratio, volatility, win rate, profit factor, risk/reward ratio, beta 📈 4 interactive charts — portfolio growth, allocation donut, P/L attribution, risk vs return scatter 💰 Live stock prices via Yahoo Finance — no API key needed 📋 Total return per position — unrealized + realized P/L using FIFO Yes, your data resets when you close the tab — that's by design. Your financial data never touches a server. But I made the CSV upload/export flow dead simple (2 clicks), so saving and restoring your portfolio is painless. The whole project is open source on GitHub, so you can fork it, self-host it, or contribute. I'd love to hear what features you'd find most useful — persistent local storage? More chart types? Crypto support? Let me know! Would love your feedback 🙏
