 At the time of its launch, Etherpad was the first web application of its kind to achieve true real-time performance, a feat previously only achieved by desktop applications such as SubEthaEdit (for Mac), Gobby, or MoonEdit (both cross-platform).Existing collaborative web editors at the time could only achieve near-real-time performance.The client-side text editor in Etherpad and its Etherpad Lite fork is implemented using Appjet's in-browser text editor, written in JavaScript.
