KongHQ at least have Kong (the proxy), which I guess they can sell enterprisy support contracts etc for. Perhaps they won't need/want to make Insomnia a subscription nightmare?
I wish Insomnia had tabs the way Postman does. Also Insomnia doesn't really have a save function, so whereas in Postman you could take a request, modify it, then close the tab without changing the underlying saved request (because you didn't save/overwrite it), you can't do that in Insomnia.
I see Insomnia on the same path. Actually I am moving the Collections to JMeter.
For what I need, it's much better and finally I can use multiple certificates for the same https domain for mTLS, which was a huge limitation in Postman
