SubEthaEdit is a collaborative text editor designed for Mac OS X.

The collaboration is document based and is non-locking and non-blocking. Anyone participating in the collaborative edit can type in the document anywhere at anytime. Using Apple Rendezvous, SubEthaEdit works without any configuration in the local subnet but can also coordinate collaborative editing over the Internet. Two popular areas of use are Extreme Programming and collaborative note taking in conferences.

Other SubEthaEdit features include:

• Regular expression search and replace in many regexp dialects
• Customizable syntax highlighting and symbol pop-up for over 20 languages. A mode for editing Wikipedia now exists.
• Full line ending and character encoding support (including Unicode)
• Live-updating web preview, showing the rendered version of an HTML document (using WebKit)

SubEthaEdit started under the name Hydra in early 2003. The name had to be changed to SubEthaEdit due to legal reasons in late 2003. The first version of Hydra was built in just a few months with the intent of winning an Apple Design Award, which it did at Apple's Worldwide Developers Conference 2003.
