Workflows, Workers - Stream Workflow instance events in your Worker or via the API with .subscribe()
Cloudflare's developer platform changelog for September 15, 2026 covers a Workflows update titled "Workflows, Workers - Stream Workflow instance events in your Worker or via the API with .subscribe()." The entry states that Workflow instance events can be streamed in a Worker or via the API, and that this is done with the .subscribe() method. The changelog is categorized under Workflows and Workers, indicating the feature spans both the workflow runtime and the Worker environment. The provided source text consists of the changelog page markup and title, so the description of the feature is limited to what the title and page metadata state: instance events are streamed, the subscription mechanism is .subscribe(), and it is available both in a Worker and through the API. No version numbers, pricing, rate limits, event types, or code samples are present in the supplied text, so those details cannot be reported. The post is dated 2026-09-15 and is published on the Cloudflare Developer Platform changelog.
Developers using Cloudflare Workflows can now consume instance events directly in a Worker or through the API via .subscribe(), per the changelog.
