Overview
Stack Auth’s current site is branded Hexclave, but public company profiles and YC still identify it as Stack Auth. It is an open-source, self-hostable developer infrastructure platform for authentication, authorization, and user management, especially for Next.js/React B2B apps. Public sources identify Konstantin Wohlwend and Zai Shi as co-founders; I did not find a separate official CEO page.
