Is Skuid limited to one sObject or Record Type per page?

No. Skuid runs in user context - respecting the Salesforce security model. This means that builders or end users can use or view any object data permitted by the security model.

Similarly, Skuid can pull multiple Record Types into the same model, and display them in the same component.

Skuid respects record type dependencies for Salesforce data elements like dependent picklists, but is not limited by page layouts.
