SunEditor supports all modern browsers without dependencies or polyfills.

🌟 Why SunEditor?

SunEditor is a lightweight, fast, and extensible WYSIWYG editor written in pure JavaScript.
It's easy to integrate, highly customizable, and built for modern web applications.

⚡ Key Features

• No dependencies — Optimized for speed and simplicity
• Modular architecture — Enable only the plugins you need
• Responsive UI — Works smoothly on all modern devices
• Framework-friendly — Easy to use with React, Vue, Svelte, etc.
• Feature-rich plugin ecosystem, including:
  • @Mentions with autocomplete
  • Advanced table editing & custom layouts
  • Math (LaTeX), drawing, and code block support (with language selector)
  • Markdown view mode (GFM) — edit content as Markdown
  • Built-in media galleries (image, video, audio, file)
  • PDF export, templates, and embedded content (audio/video/iframe)

📝 Content Editing Approach

SunEditor is optimized for structured content (articles, documentation, emails) rather than arbitrary HTML editing. Content is validated and auto-corrected to maintain consistency.

For raw HTML editing needs, see strictMode configuration in the Architecture Guide.

🌍 Browser Support

SunEditor is built to take advantage of modern browser capabilities.
It does not ship with polyfills by default, but you can add them if your project requires broader compatibility.

Works correctly on the following versions or newer.

| Browser | ≥ Version | | ----------------------------------------------------------------------------------------------------------------------------------- | --------------- | | | 119 (Oct 2023) | | | 119 (Nov 2023) | | | 121 (Dec 2023) | | | 17.2 (Dec 2023) | | | 105 (Nov 2023) | | | 119 (Oct 2023) | | | 23.0 (Oct 2023) | | | 128 (Jul 2024) |

❌ Not Supported : IE, Legacy Edge

📌 Why This Baseline? (Late 2023)

• This is based on features commonly supported by modern browsers.
• Most modern web APIs and CSS features are supported reliably in versions after this point.
• Unless specific compatibility issues arise, you can use it out of the box without additional polyfills.
• If you need support for older browsers, you can extend it by adding your own polyfills.

📦 Legacy Version (v2-legacy)

* Supported IE11

SunEditor v3 is the latest version.
This section refers to the previous stable version, SunEditor v2.

The v2-legacy branch is no longer actively maintained,
but still available for compatibility with older projects.
