Map screens to roles, not roles to screens
Every screen explicitly lists which roles need it, avoiding the default assumption that all roles see all screens.
Free MVP design tool
Map which screens and actions each user role actually needs, so B2B SaaS and marketplace MVPs are not designed with every role seeing every screen by default.
Your entries remain in this browser session and are not sent to MVPHub.
Your inputs
Enter one screen per line as Screen | roles that need it (semicolon-separated) | actions available (semicolon-separated). List every screen in your MVP.

Every screen explicitly lists which roles need it, avoiding the default assumption that all roles see all screens.
Each screen carries its available actions, so permission design can be verified against actual listed capabilities rather than assumed from the screen name.
Any defined role that appears in no screen's access list is flagged, since it likely means that role's experience has not been designed yet.
List the role under the screen, and note the view-only limitation in the actions field (e.g. "view invoices" without "update payment method") to distinguish read from write access.
It gives you a single reference table of exactly who should see what, which PermissionUX or a developer can use directly to implement access control checks.
That is a useful signal — very similar roles may not need fully separate designs, and could share a screen with minor role-conditional differences instead.
No — this maps the UX/screen visibility per role. Pair it with PermissionUX and your backend's actual RBAC implementation for full access control.

MVPHub gives a fast, structured screen-to-role map for MVP design purposes. A full RBAC workshop with a security consultant is warranted for products with strict compliance or security requirements.
