What is DuckDuckGo?

DuckDuckGo is a general purpose search engine that is intended to be your starting place when searching the Internet. Use it to get way more instant answers, way less spam, real privacy and no filter bubble, which we believe adds up to a much better overall search experience. See our about page for an overview.

Where can I test out DuckDuckGo?

Go to http://duckduckgo.com/ in your favorite browser or see the other options to use DuckDuckGo on this page: http://duckduckgo.com/tools.html

Is DDG open source?

Some of it. It's also largely built with "FOSS". We also give 10% of our income to FOSS.

What is DDG built on/with?

DDG is coded in Perl and Javascript with help of YUI, served via nginx, FastCGI and memcached, running on FreeBSD and Ubuntu via daemontools. We both run our own servers and have servers on EC2. We use PostgreSQL+bucardo, CDB, Solr, BerkelyDB, S3 and flat files for data. We monitor via Pingdom, Server Density, our own scripts and DNSMadeEasy (which we also use for DNS and failover). Finally, we have some side components that use prosody, Debian, ejabberd, jQuery, node, python and even more Perl with lots of CPAN Distributions. Also check out this architecture post, which is somewhat out of date but largely accurate.
