go-iam is a lightweight, multi-tenant Identity and Access Management (IAM) server built in Golang. It provides robust authentication and fine-grained authorization for modern applications. With support for custom roles, third-party auth providers, and multi-client setups, go-iam gives you full control over access management in a scalable and modular way.
