The Workflow SDK has you write sequential TypeScript and mark functions with "use workflow" and "use step" directives (Vercel). Unlike Temporal it runs as a client-side library against infrastructure you already have, Postgres or Cassandra, Redis or Kafka, plus HTTP endpoints, with a stateless CRUD API and no worker fleet. It adds createWebhook() for generating callable URLs inside a running workflow, generalized hooks replacing Temporal's signals/queries/updates, and FatalError/RetryableError for retry control. v5 was in beta with a claimed 5x improvement.
