I switched my mobile browser to Orion a few weeks ago and it's so great to have built-in support for Kagi. Before, I'd have to manually go to the Kagi page when I wanted to search for something since Safari doesn't support custom search engines.

Currently looking to switch from Arc to Orion. The one thing I'm gonna miss is Arc's Portrait Mode.

There is a Kagi extension that makes Kagi the default search engine.
