Stick to the point
Conversations are not linear. People change the subject all the time. SURF lets conversations branch off, so you can easily keep track of everything.

Cross-platform
SURF is designed to look and feel awesome in all current browsers.
Free
SURF is open-source, so you can run your own chat server and use it with your friends or at the office. Feel free to download or fork it from GitHub!
