Workspace App Shell vs Portal App Shell – Simple Explanation
Workspace App Shell and Portal App Shell are two different runtimes used by ServiceNow.
Workspace App Shell
Used by Agent Workspace, HR Workspace, CSM Workspace, etc.
Runs UI Builder (Now Experience) pages
URL pattern:
/now/workspace/...
Purpose: Power modern agent experiences
UI Builder pages require Workspace App Shell to run.
Portal App Shell
Used by Service Portal
Runs AngularJS widgets and portal pages
URL pattern:
/sp, /esc, /customer
Purpose: Classic end-user portal experiences
Service Portal does NOT use Workspace App Shell.
Can UI Builder pages be used in Service Portal?
No, not directly.
UI Builder pages can only run inside Workspace App Shell
Service Portal cannot natively render UI Builder pages
What about Employee Center?
Employee Center is a hybrid
Portal shell is used, but UI Builder pages are embedded
This is the recommended approach if you want modern UX for end users
Summary
Portal App Shell → Service Portal → Widgets
Workspace App Shell → Workspaces → UI Builder pages
They are separate platforms, not interchangeable
Thanks,
Danish
