Introducing Worker Previews: isolated preview environments for every change your agent makes
Cloudflare launches Worker Previews, isolated per-branch environments for testing agent code changes.
Cloudflare launched Worker Previews, giving each Git branch an isolated production-like environment with its own URL, configuration, secrets, bindings, observability, and state. Previews are started with npx wrangler preview and can run concurrently without sharing production traffic or Durable Object namespaces. The feature targets an agent development workflow in which changes are tested, observed, and revised before merge. Preview URLs can use a custom domain so authentication, cookies, CORS, and OAuth behave as they will in production.
- Each Git branch gets an isolated Worker Preview URL.
- Previews keep separate secrets, bindings, logs, and state.
- Created with npx wrangler preview under one Worker.
- Custom domains preserve auth, cookies, CORS, and OAuth.
- Aimed at testing agent changes before production merge.
