# Catalyst Cloud

Catalyst Cloud is the fastest way to try Catalyst. It's a fully managed SaaS — Diagrid hosts everything, so you don't provision any infrastructure. Sign up at [catalyst.diagrid.io](https://catalyst.diagrid.io), create a project, and connect your apps in minutes.

Catalyst Cloud is provided at no cost to evaluate the Catalyst developer experience, including:

- Durable workflows and AI agents on the Dapr runtime
- Dapr APIs for service invocation, state, and pub/sub
- Diagrid-managed Pub/Sub broker, Key/Value store, and Workflow store
- Access policies, observability, and the Catalyst web console

## What's included

Catalyst Cloud enforces resource quotas and rate limits to keep the shared environment stable for all users. These are sized for exploration and small-to-medium development workloads — they are not intended for production.

See [Plans & Support](https://docs.diagrid.io/operate/plans-and-support#catalyst-cloud-quotas-and-limits) for the full table of general, storage, networking, data-retention, and support limits.

:::note

For production workloads that need higher limits, an SLA, private networking, or a dedicated data plane, see [Catalyst Enterprise](https://docs.diagrid.io/operate/hosting/enterprise-self-hosted) or [contact Diagrid](https://docs.diagrid.io/operate/plans-and-support#contact-diagrid).
