Also perhaps try playing around in https://cloudflareworkers.com/

I don't believe Workers _Durable Objects_ specifically is available to play around with outside of the beta, however - apologies if that's what you actually wanted to play with. We're working hard on building and perfecting it into a product that everyone will be able to use soon, so keep an eye on this space.

Is there a specific usecase you have in mind? I'd love to hear about it!
