SCEditor

What SCEditor is

SCEditor is a free, open-source WYSIWYG editor for BBCode and (X)HTML that can replace a textarea on a webpage. Add its JavaScript and CSS files, then initialize the editor where the textarea appears. Its formats convert editor input and output. Listed plugins include autosaving to localStorage, YouTube link embedding, drag and drop, emoji insertion, paste-format removal, and undo and redo. Downloadable themes include default, dark, modern, Office and square; the files page also lists a core editor build with jQuery integration. Forum integrations are listed for MyBB, phpBB 3.1.x, PunBB, Question2Answer and SMF, though some are described as premium or paid. The MIT license permits commercial and non-commercial use. Compatibility includes desktop Chrome/Chromium, Safari, Firefox, Edge and Opera, as well as mobile browsers including iOS 5+ and Android Browser on Android 4.0+. On browsers without WYSIWYG support, the editor is disabled by default and leaves the plain textarea; source mode can be enabled with an option. The documentation advises server-side BBCode conversion and sanitizing submitted HTML to prevent XSS.
