How does Diagrid Catalyst differ from AWS Step Functions?

Catalyst is purpose-built for agentic durable execution, unlike AWS Step Functions which targets cloud-native workflow orchestration. Catalyst runs on Dapr, supports both deterministic and probabilistic agent work, preserves state through interruptions, while Step Functions’ cloud-bound scheduler model poorly fits dynamic, cross-cloud agent tasks. Note that durable execution does not equate to exactly-once delivery, and verify competitor features via their official documentation.
