Reality is that Insomnia offers plenty of ways to still run locally, but now it does it in a sustainable way that allows us to improve the product even more.
I forgot to add that users can also create "Private Environments" which are always local and never synchronized with Insomnia Sync (in the cloud) or Git Sync.
For what it's worth, I first switched to Insomnia from Postman, years ago, when they pulled a similar stunt.
Rest assured, although I created an account earlier (to gain access to my collections which simply seemed to disappear overnight), I'll be switching away from your product, so don't count that account creation as a win in your metrics. Not impressed with how this has been handled at all. It seems there are very few trustworthy companies in tech anymore.
