FinView: Claude Code powers Finviz alternative with EODHD API

FinView is a fully functional, open-source Finviz clone built with Claude Code and wired to a single EODHD endpoint for real-time quotes, fundamentals, and sector data [Dev.to]. The dashboard displays a market-wide snapshot that aggregates S&P 500, Nasdaq, Dow Jones, and Russell 2000 values, plus advance/decline ratios and a bullish-bearish sentiment gauge. The screener reproduces Finviz’s core filters—price, volume, relative performance, and technical signals—and adds a heatmap that highlights sector rotation in real time. Each stock card pulls live price, 30-day historical performance, and key fundamentals (PE, market cap, dividend yield) from the EODHD API with a single HTTP call, such as a Python request to https://eodhd.com/api/real-time/AAPL?... returning a JSON payload that the front-end parses to populate the UI [Dev.to]. The repository also includes a reusable Claude Code template that auto-generates CRUD endpoints for new data types. Claude Code reduced development cycles by generating repetitive logic, allowing the author to complete tasks in under 48 hours that previously required weeks of manual API wiring and UI design [Dev.to]. By relying on EODHD’s unified feed, FinView eliminates the need to maintain three separate vendor contracts, cutting latency, error handling, and cost overhead. The full source code, including Claude Code templates and EODHD integration patterns, is publicly available, allowing developers to fork the project, replace the data provider, or extend the screener without starting from scratch.
