Frequently asked questions
What is an RBAC matrix?
An RBAC (Role-Based Access Control) matrix is a visual table that maps user roles against system resources and operations. It clearly outlines which roles have permission to perform specific actions like reading, creating, or editing data.
How can I integrate the exported JSON into my application?
The exported JSON contains structured role-to-permission mappings. You can parse this file directly in backend frameworks like Node.js, Django, or Spring to enforce authorization middleware and policy checks.
Is the RBAC matrix builder free to use?
Yes, this tool is completely free with no registration or subscription required for standard use.
Does this tool store my permission policies on your servers?
No, the builder runs client-side in your browser. None of your role definitions, resources, or permission matrices are transmitted to or stored on Doffl servers.
Can I define custom actions beyond basic CRUD operations?
Yes, you can add custom actions such as publish, approve, or export alongside standard create, read, update, and delete actions for any resource.
