Builds Cloudflare's durable execution engine into your Workers. This went GA in April 2025 and got a serious speed boost in October with 10x faster instance creation and 10,000 concurrent instances. You get proper step-based workflows with state persistence up to 1GB, waitForEvent for external triggers, and actual testing tools through the cloudflare:test module. The limits are reasonable: 1,024 steps max, 5 minutes CPU time, and waiting instances don't eat your concurrency quota. Good choice if you're already on Cloudflare and need reliable multi-step processes without managing your own state machines or job queues.
