Diagrid Catalyst
Run durable workflows, AI agents, MCP servers, and Dapr applications across managed, BYOC, or self-hosted deployments.
Diagrid Catalyst provides managed Dapr APIs, durable workflows, identity, and policy controls for distributed applications and agents. Its control plane and runtime data plane can run in Diagrid-managed infrastructure or supported customer-controlled deployments, while customers continue to host their application code separately. Managed backing services are available for some APIs; other components connect to customer-operated infrastructure.
Best for
Platform teams operating Dapr applications, durable workflows, AI agents, and MCP servers across multiple clusters, clouds, regions, and infrastructure environments.
Watch out for
Catalyst is an orchestration, identity, policy, workflow, and managed API layer. It does not host or execute the customer's application code, and production deployments may still require customer-operated compute and backing services.
