Developers: Build Sidebar Apps for Epic!
It’s easy to build sidebar applications for Epic. You have two options.
Web App. This is the simpler option. In this case, you need to re-design or build your web app in a thin format. Specifically you need to send us a url to a webpage that has a width ideally of 320 pixels and no more than 340 pixels. We can then simply embed the web url in a sidebar in Epic.
Mozilla Add-On App. If you’d like to develop an app that interacts more deeply with the browser, you can use XUL, XBL, XPcom and other Mozilla technologies to build an app that installs as an add-on for Mozilla.
