About
Etherpad lite is a really-real time collaborative editor spawned from the Hell fire of Etherpad. We're reusing the well tested Etherpad easysync library to make it really realtime. Etherpad Lite is based on node.js what makes it much ligther and more stable than the original Etherpad. Our hope is that this will encourage more users to install a realtime collaborative editor. A smaller and well documented codebase makes it easier for developers to improve the code. Etherpad Lite is optimized to be easy embeddable
Online demo
Visit http://pitapoison.de:9001 to test it live. You can find the same instance behind a nginx, with ssl and in a subpath here -> https://pad.pitapoison.de/pad/
