Open Source Commerce
Commerce for humans and agents.
In ancient Greece, the Stoa was the covered walkway where merchants, philosophers, and citizens gathered to trade and exchange ideas. Today, Stoa is where developers, businesses, and AI agents come together to build the next generation of commerce.
Built on Go, Stoa handles thousands of requests per second with minimal memory footprint. No bloat, no unnecessary overhead — just raw performance where it counts.
