This seems cool, but the progress that HEY has made since launch isn't very impressive if that's the flagship example.
HEY's search UX, which uses these capabilities, has been abysmal since the day it launched. It's a much better experience if you disable JavaScript/Hotwire and fall back to the server-side-rendering instead of the hybrid mess they push down. I'm very disappointed that this hasn't been improved. (I sent feedback about this while they were still in their invite-only phase.)
We were also promised custom domain support by the end of the year, and we don't have a timeline or even pricing yet. (That's obviously backend and unrelated to this announcement.) I don't want to go back to Google, but the lack of improvement isn't giving me a lot of confidence as a HEY customer, so I'm considering alternatives.
