any known multiplatform http clients that don't use coroutines?

You can use curl lib directly. I’ve been doing it until I’ve started use ktor-curl-client.

I'm curious about why you're looking for one that is not using coroutines 🤔

coroutines are currently very heavy on browsers. So, I am doing my best to avoid them if I am writing code that is eventually going to be executed by one. Also, curl lib isn't multiplatform, as I believe it doesn't work in browsers

@andylamax I suggest you to follow this issue: https://youtrack.jetbrains.com/issue/KTOR-1084

Thanks @Daniele B I already follow that issue
