did you mean Vercel? if so you cannot. self-hosted or local.

it’s almost same as Cloudflare Worker so Miniflare could work depending on ur issues

No it's not possible to change the runtime for middleware. What is the issue with logging you have?

@European sprat Pino doesn't support edge. I have found a sort of work around, but none of my mixins are applied, so its half a solution right now.

Why does middleware run in Edge?

Pino works but it works as if it's being run in the browser. Not sure about the mixins
