https://casbin.org/ (multiple approaches, multiple languages, provider) Open source authZ library that has support for many access control models (ACL, RBAC, ABAC, …) and many languages (Go, Java, Node.js, JS, Rust, …). While somewhat complex, it is also powerful and flexible. They also have their Casdoor platform, which is authN and authZ provider.

Looks like you’re looking for a role-based access control (RBAC) module on your backend. What you would do is attach roles to your users/tokens which would allow or deny any specific action on a resource. Take a look at https://casbin.org/ that might be useful.

Looking at your username, it would be nice to mention that you are one of the main developers behind the tool instead of making it sound like you are unrelated: https://github.com/casbin/casbin/graphs/contributors https://github.com/casdoor/casdoor/graphs/contributors

We use casbin . We’re using python version, but it has libraries for many languages. There are some adapters for loading policies from a datastore but we are not using any of them

ZITADEL Cloud — A turnkey user and access management that works for you and supports multi-tenant (B2B) use cases. Free for up to 25,000 authenticated requests, with all security features (no paywall for OTP, Passwordless, Policies, and so on).

One of the challenges we see is providing self-service for team management. That includes letting an admin assign roles to their users, manage user lifecycle (eg through sso), and setting up security policies. For sure you can build the basics, but it becomes complex later on if you manage a lot of tenants or or more enterprise customers. For Auth only there are many solutions out there that work great. There's only a few solutions with multi-tenancy at the core, though, like https://github.com/zitadel/zitadel
