Hello all @Wrangler dev users! Over the last few months we’ve been working hard to refactor the internal implementation of wrangler’s dev servers. We’re really excited about the stability improvements this brings and the exciting opportunities it will unlock in the future! We’d love for you to give this a go on your Workers and let us know how it goes! 🚀

Try it out with the new --experimental-dev-env flag (shorthand: --x-dev-env) on wrangler v3.62.0 or newer:

$ npx wrangler@latest dev --x-dev-env
# or
$ npx wrangler@latest dev --remote --x-dev-env


If you come across any bugs feel free to create an issue at https://github.com/cloudflare/workers-sdk/issues/new. We’d also love to hear if it works for you without any bugs! We’ll be actively monitoring for these issues and feedback until July 8th before deciding to enable the flag by default.
