wysihtml5 - an open source rich text editor based on HTML5

wysihtml5 is an open source rich text editor based on HTML5 technology and the progressive-enhancement approach. It uses a sophisticated security concept and aims to generate fully valid HTML5 markup by preventing unmaintainable tag soups and inline styles.

Features:

• It's fast and lightweight (smaller than TinyMCE, Aloha, ...)
• Auto-linking of urls as-you-type
• Generates valid and semantic HTML5 markup (even when the content is pasted from MS Word)
• Uses class names instead of inline styles
• Unifies line break handling across browsers
• Uses sandboxed iframes in order to prevent identity theft through XSS
• Speech-input for Chrome
• No jQuery required
