Worker Previews gives each branch its own running environment

Cloudflare Worker Previews gives each Git branch a stable URL, configuration and runtime observability. Durable Objects and Containers receive separate state for the preview, so developers and agents can test migrations and interactions before merging. The separation is not universal yet: service bindings still reach the bound Worker’s production deployment, and previews cannot consume Queue messages.

Why it matters

Useful for teams whose agents need to verify running behavior rather than only inspect code.

More context

Try the released feature with a Cloudflare account, Wrangler and explicit preview bindings and secrets. Use the branch URL and traces to reproduce a failure, change the code and check again. Review external dependencies before treating the environment as isolated.

Keep in mind

Production-like does not mean a complete production clone. Workflow isolation needs separate configuration, and platform usage costs apply. 1min has not deployed or tested this feature.
