Thanks for the question.

For people using these Instant Answers, they are generated on our servers with a small amount of JavaScript for displaying, so CPU usage and caching storage should be not much more than regular DuckDuckGo search result pages.

For developers creating these Instant Answers, we've worked with Codio to offer all contributors free access to their service which is an online development environment. Because of this, developers don't need to install a server or framework - it's all handled in the Codio web app.
