Not one click but by no means a byzantine process
If this doesn't scare you already, I'll rephrase: Your queries may be sent to the built-in search engines even if you think you're only using Kagi! It does not actually replace the need for real custom search engine support in Safari. The official Kagi docs coyly acknowledge this [1]:
> For a better experience, we recommend selecting a single search engine to redirect (DuckDuckGo or Ecosia are recommended options as they have better privacy policies than other alternatives).
[0]: It's an amazingly portable device made ahead of its time - Apple really should revive this form factor and stick an M1 chip in it. [1]: https://help.kagi.com/kagi/getting-started/setting-default.h...
Unobvious. Not hard. To the chasm that is getting someone to pay for search, getting them to install an app and follow tedious but simple configuration instructions is a gap in the sidewalk.
When all it should've been is a "custom search engine" option like Firefox does.
Calling it "unobvious" is PR newspeak for jumping through the hoops to set up a Rube Goldberg machine to do a basic search.
There was a period of time when they had two apps, and I agree the old one was stupidly complicated. The new one, Kagi for Search, doesn't require this.
Like, should Apple have an open API for routing searches? Maybe. Would that get abused? Probably. Do I think Kagi should be on Apple's list? Yes. Does prioritising a 50,000-user engine into iOS's defaults create other issues? Yes as well.
Eventually I gave up and uninstalled their extension. I switched to using StopTheMadness to do the redirects instead, and am having much better luck. I did switch from redirecting Google to redirecting Ecosia at the same time, and this might be the difference, and while I'd fully agree that Safari doesn't make it easy, but I think the base problem is that their browser extension just doesn't work that well.
(If you are familiar with both, you will understand that switching _to_ StopTheMadness for a better interface is pretty high in irony!)
This is a clever workaround by Kagi, but a glaring hole in the Safari extension API surface area.
I have Kagi set as the default search engine in the Orion browser.
The main problem I experience on iOS is that apps that open websites will pick Safari, and not my default browser. I'm sure they have some legitimate excuse, like "the app developer made that choice", or "that other browser doesn't support the right API" or whatever bullshit that makes the default browser not the default.
