Here's your **Weekly GitHub Roundup: Finance Edition** for the week of April 4–11, 2026. I've curated standout open-source repos in fintech, quantitative trading, personal finance, crypto/DeFi, and AI-driven finance tools based on trending activity, stars gained, updates, and relevance. Focus is on practical, actively maintained projects for developers, quants, and traders.
