Temporal Catalog

The Catalog is a local-development page in temporalio/ui for browsing and running Temporal workflow examples. Examples are declared in code, generated into artifacts the browser reads, and executed by a worker this repository starts.

The catalog is only reachable in local development. Every other environment returns 404.

Start here

pnpm catalog dev

This runs the UI and the catalog worker together and prints a banner with the catalog URL and each target's namespace and task queue. Open the URL it prints, which looks like:

http://localhost:3000/namespaces/default/catalog

pnpm dev is unaffected by the catalog and never starts a worker. To run the pieces separately, use pnpm dev in one terminal and pnpm catalog worker in another.
