I disagree with the idea that live coding demos are universally bad. In cases where they are practiced and calculated, they actually convert better than slides. I don&#x27;t have any hard numbers on hand to back that up, but I worked as a developer evangelist for SendGrid for a couple years and I&#x27;ve probably spent too much time thinking about and attending Hackathons, so I feel ok speaking from experience. At any given Hackathon getting 10% of teams to use your product or API is impressive. Whenever someone has a polished live code, interactive demo I can assume it&#x27;ll easily hit that mark. Being able to demo you API live in 5 minutes is a pretty strong guarantee that it&#x27;ll be easy enough to implement during the weekend. Plus, developers love to see code and understand how other developers think!<p>I wrote about how to give a great API demo a few years ago. Points are still true, worth a read if you&#x27;re thinking about live coding: <a href="http:&#x2F;&#x2F;theycallmeswift.com&#x2F;2013&#x2F;02&#x2F;01&#x2F;the-elements-of-a-great-api-demo&#x2F;" rel="nofollow">http:&#x2F;&#x2F;theycallmeswift.com&#x2F;2013&#x2F;02&#x2F;01&#x2F;the-elements-of-a-grea...</a>
