I love what the kagi team is doing, and being some of the first innovators maybe since the ladybird(?) browser, even if it's using the same base of webkit, not being a fork of chrome or firefox. I wish they'd bring it to android, but it doesn't look like they're interested.
Kagi is a pretty small team and they’ve got a LOT on their plate. Orion started on macOS and was in development for 6 years before finally hitting their 1.0 release in November. Give it time - I’m sure they’d love to support just about every major OS and platform.
It is interesting that they don't mention future Android support anywhere on the website, but it does seem like they are (or at least were) open to the idea someday.
