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.
It sounds like you’re talking about Orion (the browser developed by Kagi) rather than the Kagi search engine, which is what this pricing update is about. The search engine is a normal website that’s not limited to any particular device or browser, and as far as I know has no location or device limits.
That’s just the browser though (Orion) — the main product, the search engine, has no Apple focus. I believe a significant part of why they built the browser is because Safari on iOS doesn’t have good support for third-party search engines. You shouldn’t have any such issue on Android.
The search limits are per account. As long as you’re signed in, you’ll be fine.
Edit: Also, the browser is WebKit, not Chromium. That’s why it’s Apple-only.
