About AlphaLoupe
A market workspace without artificial caps
The best charting tools have shown how capable a browser-based market workspace can be. But familiar essentials—more indicators, larger watchlists, lasting alerts, replay, deeper minute history, and an ad-free screen—are often held behind plans costing hundreds or thousands of dollars a year, even when lifting those limits adds little cost.
AlphaLoupe starts from a different premise: a polished, full-featured workspace can be free and still respect its users. We are building our own product, design language, and information architecture for the web, iPhone, and iPad, with generous tools, transparent data freshness, no ads, and no tracking.
