SunEditor review
A free, extensible editor with unusually broad media, table, and content tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SunEditor is a free, open-source WYSIWYG rich text editor for modern web applications. Built with vanilla JavaScript, it supports formatting, fonts, colors, alignment, block styles, structured content, and configurable editing modes including classic, inline, balloon, and document layouts. It suits developers building content fields, document editors, publishing interfaces, and other web experiences that need more than basic text input while retaining control over deployment and integration.
Its strongest distinction is feature breadth within the editor itself. SunEditor combines advanced table editing and custom layouts with image, video, audio, and file galleries, iframe embeds, Markdown view using GitHub Flavored Markdown, templates, math, drawing, code blocks, and PDF export. A modular plugin architecture lets developers configure toolbar buttons, while the custom plugin API and TypeScript support provide additional extension options. This makes it a strong fit for applications with varied content requirements, especially when media handling and structured editing matter as much as text formatting.
Integration coverage is another practical strength. SunEditor can be installed through npm or loaded from a CDN, and it provides integration options for HTML, JavaScript, React, Vue, Angular, Svelte, and Web Components. The trade-off is that deployment is self-hosted, so implementation teams remain responsible for incorporating the editor into their application. Teams seeking a focused, configurable editor with wide media and framework support should consider SunEditor. Teams that require documented real-time collaboration should choose a product built around that capability instead.
