Summary
Stack Auth builds an open-source authentication, authorization, and user management platform for developers. Founded by repeat founders Konstantin Wohlwend and Zai Shi, who both previously went through YC, they solve the pain of existing auth solutions that are difficult to set up and lack features beyond basic authentication. Stack Auth includes organizations, permissions, RBAC, customizable React components, self-hosting options, and a managed cloud service that can be set up in one minute.
