I'm probably going to try this out for its websocket support. I use Postman, they've had a long-standing open issue to add it with no ETA/progress: https://github.com/postmanlabs/postman-app-support/issues/40.... Haven't used Insomnia but they don't mention websockets anywhere in their docs so I assume they don't support it either: https://support.insomnia.rest/search?collectionId=&query=web...
