I've run the open source version of Insomnia (https://github.com/ArchGPT/insomnium) for a while, but as that project is no longer actively maintained, I may give this a look.
He sold it some time ago. Either it expired, he negotiated out of it, or there was never much of one to begin with. My guess it was a little of all three. I think a lot of what Kong wanted with it already happened - it seems to have helped them grow. They still have it and it's still helping but I don't think Yaak is that big of a threat to it. Kong still has a major API client in a space that has room for more than one.
It feels like they were after a similar strategy as when Fiddler was sold. They can control the narative and likely use it as an onramp to their other (much more expensive) products when developers introduce any of their tolling into the enterprise.
