I got frustrated that school covers personal finance for one semester and most kids forget it by graduation. So I spent the last several months building Finly — a free financial literacy platform for kids ages 8-17. 90+ lessons across budgeting, credit, taxes, investing, and finance careers (IB, VC, PE, quant) Stack: Next.js, Supabase, Vercel Building the portfolio simulator meant downloading 3 years of daily price data for 503 S&P 500 tickers and migrating it to Supabase Posted on Hacker News today and got 839 visitors in a few hours. No ads, no paywall, no account needed to start. Incorporated as a nonprofit. learnfinly.com
