ory/ladon: A SDK for access control policies: authorization for the microservice and IoT age. Inspired by AWS IAM policies. Written for Go. @GitHub
"Ladon is a library written in Go for access control policies, similar to Role Based Access Control or Access Control Lists. In contrast to ACL and RBAC you get fine-grained access control with the ability to answer questions in complex environments such as multi-tenant or distributed applications and large organizations. Ladon is inspired by AWS IAM Policies."
