I looked into Kagi a week or so ago from a different HN link and was turned off by the Apple-focus. I've had bad experiences in the past with early adopting and regretting it because I don't use Apple products. I understand they plan to support non Apple stuff but it's never clear if that support will be first-class and it often isn't. Considering that it's a Chromium wrapper, it seems odd that they took this route.
It's also not clear if there are device/location limits for an account. I use a lot of devices and travel quite a bit.
