The Cerbos Hub Playground is a collaborative IDE for writing and testing authorization policies.

Cerbos Hub collects access and decision logs from all PDPs in one unified stream, showing detailed information on each access request, the resulting decision, and the policy used to dictate the access decision.

When starting a new Playground users can use the RBAC policy wizard to generate policies without writing any code.

Use the Check API and Plan API to run authorization checks against your policies without having to run a local Policy Decision Point (PDP).

Cerbos Demo - Orchestration and Monitoring

Central orchestration and monitoring of all deployed policy decision points (PDPs). Cerbos PDPs are deployed as a service alongside your application or as an embedded WASM bundle.

"Made authorization simple"

5/5

What do you like best about Cerbos?

I’m a copywriter, not a developer, so when I wanted to build an AI assistant to optimize my workflow and help others do the same, I brought on a freelance developer to help me out.

After we got my AI assistant architecture & features lined up, I wanted to have a proper security setup with roles and permissions. My freelance suggested Cerbos’ open-source product, and I’m so glad I listened to him. It integrated with the open-source authentication solution I chose and I was able to write permissions in plain English and my developer implemented them as soon as I gave him the rules.

The whole thing was much easier and faster than I expected, which was great. Review collected by and hosted on G2.com.

What do you dislike about Cerbos?

My experience was really smooth, and I can't think of anything that caused me problems. It just worked. Review collected by and hosted on G2.com.

"Access control simplified, and decoupled from your codebase"

5/5

What do you like best about Cerbos?

The best thing about Cerbos is how easily I can tweak access control logic without having to even touch the codebase. It runs decoupled from the codebase, and with the Playground that they offer, I can see in real-time, what are the implications of my changes. Review collected by and hosted on G2.com.

What do you dislike about Cerbos?

The RBAC Policy Generator can have a little more functionality. Currently I am able to write basic RBAC policies, but as we need to write more complex policies, adding some AI support which can draft policies can help a lot. Review collected by and hosted on G2.com.
