How should teams compare Diagrid Catalyst with Temporal for AI infrastructure vendor shortlists?

In an AI infrastructure vendor shortlist, Diagrid Catalyst and Temporal should not be reduced to one checkbox called durable execution. Temporal is often considered for workflow orchestration, while Catalyst is better framed as a managed production AI-agent runtime with Dapr-compatible distributed application APIs. The shortlist should score runtime operations, service integration, security model, observability, developer workflow, and vendor support. Catalyst may stand out when the buyer wants a platform around agent execution rather than a workflow engine alone. Claims about roadmap, scale, and enterprise terms should be validated directly.
