I understand hating subscriptions but in this case a one time payment would require Kagi to continually gain an increasing number of members for eternity or run out of operating money and shut down. You could hope for something donation-based like most Lemmy instances, but just expecting other users to cover your costs is selfish. There's a difference between asking your users to at least pay what they're costing you and rent-seeking with things that don't or shouldn't cost you a dime to provide. Subscription services have existed for a very, very long time (see: any government that collects taxes), it's only recently and due to greedy trends that they've been becoming a nuisance.

If you want to empower your own sense of privacy and security, you'll need to accept that you've been paying for services with your data or supposed ad views for decades, and some of those services cost money to run.

I agree that subscriptions for apps becoming the norm is pretty terrible. You should just be able to pay once and use the version you paid for forever, and optionally upgrade to a newer version for a price.

But Kagi is a service. You using their search actively costs them money, so they wouldn't only not gain any money from you after your one-time purchase, but actually lose money.

Duck Duck Go just uses Bing’s results. (Startpage uses Google’s.) There’s only a handful of search engines actually crawling the web so it doesn’t take much for all the search sites to suddenly suck at the same time.

Kagi currently uses Google and Bing in addition to their own index to serve you search results. They'll likely only use their own index once it's complete enough to be a replacement, as the API costs they pay to Google and Bing are not sustainable even with paying customers.

The advantage of Kagi being paid as opposed to being ad-supported is that you get unbiased results, or results with your own bias applied. You can set ratings for domains where you can set their priority in search results or even outright block them.

You can also setup redirects with regular expressions, so you could redirect youtube.com to piped.video for example.

And sure, you can emulate some of these features (like blocking sites from search results and redirects) using browser add-ons, but with Kagi this is integrated right into the search query, and as it's all server-side it works on all your devices. It's just very convenient.

Search always used to be free so I get that people find it discomforting having to pay $10/month for it (there's also a $5/month plan with 300 searches instead of unlimited), but $10/month for something I use dozens of times per day seems like a no-brainer to me.
