Ask HN: What's the best metasearch engine?

What kind of metasearch?

For web metasearch, DuckDuckGo has taken the crown from Metacrawler, and is easily the best thing out there.

As for the rest... I don't know.

This may or may not be what you're looking for, but you should check out my company's product, Meta Search. Our website is https://www.meta.sc and our product provides a really powerful search experience across a bunch of different cloud platforms as well as local devices. Happy to answer any questions you may have!

try http://searx.me/ it is open source, also available as a docker instance.

besides web interface it also offers RSS, CSV and JSON api. supports about 10 search engines.

you can query it in curl or write a simple api client with rest-client
