  • It's got Admin/Non-Admin roles. That's good enough, right?

    Absolutely! Decoupling your authorization layer and your application logic is the most important thing to do. Whether from that point you go with a vendor, build with open source (Like OPA and OPAL), or build yourself is up to you, but if you mix them, you're going to have a terrible time regardless.

  • Do you prefer to build your own auth, or use some library or provider (like auth0, Next Auth, Supabase, etc)?

    If you do decide to build AuthZ on your own, there are best practices you should follow. If you don't want to be spending a huge amount of time and effort on building something like that yourself, there are plenty of open-source tools that can help (OPA, OPAL), or you can just use something ready-made like that can save you the trouble altogether.

    Supertokens is awesome, a bunch of open-source solutions give the flexibility of managing authN and authZ, and they tend to be very well maintained. There are also open-source projects to help you with building authorization like OPA and OPAL.

    One such XACML alternative is OPA + OPAL. Open Policy Agent (OPA) is an open-source project created as a general-purpose policy engine to serve any policy enforcement requirements that unifies policy enforcement across the stack without being dependent on implementation details. It can be used with any language and network protocol, supports any data type, and evaluates and returns answers quickly. OPA’s policy rules are written in Rego - a high-level declarative (Datalog-like) language. You can find a more detailed introduction to OPA here. It’s important to note that OPA itself only provides an alternative to XACML’s PDP (More on that further). OPA is enhanced by OPAL (Open Policy Administration Layer) - another open-source solution that allows you to easily keep your authorization layer up-to-date in real-time. More information about the project is available here. The combination of OPA and OPAL provides a solid alternative for XACML.

    OPAL is a mature open-source project which is already keeping hundreds of policy agents updated in real-time. You can join OPAL’s Slack community to chat with other devs who use OPAL for their projects, contribute to the open-source project, or follow OPAL on Twitter for the latest news and updates.

    This way, OPA is able to make policy decisions based on the most recent policies and data. A deeper dive into OPAL’s architecture and communication flows is available in OPAL’s documentation.

    OPAL is an open-source project for administering authorization and access control for OPA. OPAL responds to policy and data changes, pushes live updates to OPA agents, and thus brings open policy up to the speed needed by live applications.
