Xinha is a powerful WYSIWYG HTML editor component that works in Mozilla based browsers as well as in MS Internet Explorer. Its configurabilty and extensibility make it easy to build just the right editor for multiple purposes, from a restricted mini-editor for one database field to a full-fledged website editor. Its liberal, BSD licence makes it an ideal candidate for integration into any kind of project.

Xinha is Open Source, and they take this seriously. There is no company that owns the source but a community of professionals who just want Xinha to be the best tool for their work.
