Information in this Gist originally from this github issue, which is outdated.

As @RomanMinkin mentioned, you can also consider Casbin (https://github.com/casbin/casbin). It is the most starred authorization library in Golang. There are several differences between Casbin and OPA.

Feature	Casbin	OPA
Library or service?	Library/Service	Library/Service
How to write policy?	Two parts: model and policy. Model is general authorization logic. Policy is concrete policy rule.	A single part: Rego
RBAC hierarchy	Casbin supports role hierarchy (a role can have a sub-role)	Role hierarchies can be encoded in data. Also with the new graph.reachable() built-in function queries over those hierarchies are much more feasible now.
RBAC separation of duties	Not supported	Supported: two roles cannot be assigned together
