Personally, it was Insomnia shifting to requiring an account and promoting "enterprise" features that clutter the experience and get in the way of me doing my job.

From there, I did research and found `insomnium` and a coworker found `bruno`. Bruno aligned closer to what I value, so now I use that.

Oh wow, I never noticed. It appears I’m running a ~1 year old version (2023.4.0) that just stopped auto-updating. It doesn’t have any restrictions and doesn’t require an account.
