Authorizer: Open-source authentication and authorization for your apps

Authorizer, an open-source authentication and authorization server written in Go, now includes a permissions engine and an interface for AI agents in the same program that handles user sign-in, allowing a chatbot to check whether a user may see a document before fetching it. The project's maintainers position the tool for teams that run sign-in and access control on their own infrastructure and keep user accounts in a database of their choosing.
