We're a community of open source developers from around the world, contributing code to improve the DuckDuckGo search engine.

• Create new Goodie Instant Answers, and improve existing ones
  • Note: Goodies are written in Perl (back-end) and JavaScript (front-end). They can also typically use CSS, and Handlebars Templates.
• Visit DuckDuckHack to learn more about how you can help!

Goodies do not retrieve data from a third party API. Goodies provide their results entirely through server-side code. They may use a static data file stored on DuckDuckGo's server, but they do not call external resources.
