Kagi isn't trying to take significant market share from Google or DDG, but find a niche (probably Hacker News type people). The one thing I find they're lacking is maps and location based results (e.g. you can't search for "lunch near me"). If you're interested, I'd recommend checking out their FAQ: https://kagi.com/faq
Edit: This is really promising and interesting. They show a summary of the link when you hover over the crystal ball icon next to it, together with a button for "Block" and "Boost" - i.e. you can vote with your account. These metrics could be used for ranking and kill affiliate marketers.
If they're not ready to charge for use yet, a limited preview makes more sense than a public free service.
> DuckDuckGo gets its results from over four hundred sources. These include hundreds of vertical sources delivering niche Instant Answers, DuckDuckBot (our crawler) and crowd-sourced sites (like Wikipedia, stored in our answer indexes). We also of course have more traditional links in the search results, which we also source from multiple partners, though most commonly from Bing (and none from Google).
