Build durable workflows on Catalyst

This section is for developers who orchestrate long-running processes with Catalyst Workflows. A workflow on Catalyst picks up where it left off after a crash, a deploy, or a restart, and it can run for hours or days. Catalyst can also sign each step of a workflow's history, so you can prove how a run went.

You write workflows in .NET, Go, Java, JavaScript, or Python.
