Score: 4.3/10 (Innovation: 4, Technical: 6, Documentation: 2, Utility: 3)

SciTrader is a technology showcase for a crypto trading app that combines WebGPU-accelerated charting on the front-end with QuestDB for trade ingestion on the back-end. It features a custom protobuf-style binary compression middleware that achieves 10x data reduction over JSON for quotes, trades, and L2 data. The project demonstrates high-performance visualization and data handling for financial markets but is positioned as a demo rather than a production-ready tool.

Target audience: crypto traders, financial data engineers, web performance enthusiasts
