12 Open-Source WYSIWYG Editors Worth Using in 2026

You want something your users can figure out without a tutorial, something you can drop into a React component or a plain HTML page without fighting 40 npm dependencies, and ideally something that won’t lock you into a SaaS subscription the moment you need a feature past the free tier. That rules out a lot of options fast, and it leaves you with a shortlist of open-source editors that are genuinely worth your time in 2026.

These 11 are actively maintained, have real communities behind them, and cover different use cases, from lightweight inline editors to full document processors, so pick the one that fits the job.

1. TinyMCE

TinyMCE is the most widely deployed open-source WYSIWYG editor on the internet. It powers WordPress’s classic editor, ships inside dozens of enterprise CMSes, and has been in active development since 2004. If you’ve used a content management system at any point in the last 15 years, you’ve almost certainly typed inside a TinyMCE instance without knowing it.

The self-hosted open-source version covers everything most projects need, including toolbar customization, table editing, image handling, code blocks, and a plugin system with over 50 official plugins.

The cloud version adds AI features and premium plugins behind a paid tier, but you can ignore all of that and run the open-source build entirely on your own infrastructure.

2. CKEditor 5

CKEditor 5 is the most feature-complete open-source editor on this list. It handles complex document structures, tables with merged cells, nested lists, custom block elements, and real-time collaboration, and it integrates with Angular, React, and Vue with first-party packages.

The open-source GPL version gives you the full editing engine. The commercial version adds cloud collaboration and AI features, but for a self-hosted project the GPL build is comprehensive enough for almost any use case.

3. Quill

Quill has been around since 2012 and it’s still one of the most embedded WYSIWYG editors on the web. It’s lightweight, well-documented, and uses a flat data model called Delta that makes it easy to reason about document state, sync content, and build collaborative features on top.

It works via a CDN drop-in, which means no build toolchain required if you just want something running fast. And the API is clean, so programmatically formatting text, inserting content, or reading output is straightforward.

4. TipTap

TipTap is a headless rich text editor built on top of ProseMirror, and it’s become the default choice for developers building custom editing experiences in React, Vue, or plain JavaScript.

Headless means it ships with zero default styling, so you own the UI completely and it has a proper extension system, so you can add custom nodes, marks, and commands without forking the core.

The free tier covers most production use cases, but extensions like collaboration via Hocuspocus, AI commands, and some advanced block types are behind a paid plan, but you won’t hit that wall until you’re building something fairly complex.

5. Froala (Community Edition)

Froala is primarily a commercial editor, but it has a community edition that’s free for open-source projects. It’s mature, has a clean UI out of the box, and handles image insertion, tables, and inline styles without configuration.

If your project qualifies for the community license and you want something that looks good without CSS work, it’s worth including in your shortlist.

Check the license page carefully before shipping it in a commercial product. The community terms are specific about what qualifies, and it’s easy to misread the scope.

6. ProseMirror

ProseMirror is the editing engine that powers TipTap, Atlassian’s editor, The New York Times‘ CMS, and a dozen other serious editing tools. Using it directly means you’re building on the same foundation those tools use, but without any abstraction layer on top.

The API is low-level and the documentation assumes you already understand how rich text editing works. If you’re building a product where the editor is a core differentiator and you have engineering resources to invest, ProseMirror gives you the control that TipTap’s extension system doesn’t always expose.

7. Editor.js

Editor.js takes a completely different approach from traditional WYSIWYG editors. Instead of treating a document as a stream of formatted HTML, Editor.js works with structured blocks, where each paragraph, heading, image, or list is a discrete JSON object. The output is clean JSON, not HTML soup.

That makes it excellent for CMS projects where you need to render content differently depending on context, or where you want to validate, search, or transform document content on the backend without parsing HTML strings.

8. Slate.js

Slate.js is the editor framework you reach for when you need total control and you’re comfortable writing more code. It doesn’t give you a toolbar or a ready-made UI. It gives you a data model, a rendering layer, and a plugin API, and you build everything else. The payoff is that you can create exactly the editing experience you want without hacking around someone else’s architecture.

It’s used in production at companies building complex document editors, and it handles unusual node types, embedded components, and custom rendering well. But if you want something running in an afternoon, start with TipTap or Quill instead.

9. Toast UI Editor

Toast UI Editor ships with 2 editing modes in one package: a Markdown editor and a WYSIWYG editor with a live toggle between them. That combination is genuinely useful for developer-facing tools, documentation sites, or any context where some users prefer writing Markdown and others prefer clicking toolbar buttons.

It has syntax-highlighted code blocks, table editing, and an image upload API built in. The output is clean Markdown, and the rendering quality is solid.

10. Jodit

Jodit is a classic toolbar-style WYSIWYG editor written in pure TypeScript with no external dependencies. It has over 100 options, a file browser, inline editing mode, and a dark theme. And it works in a plain HTML page without any framework at all, just a <script> tag and a textarea.

That makes it one of the easiest editors to drop into an existing PHP or server-rendered application without touching your build pipeline. It’s heavier than Quill but lighter than CKEditor, and it covers the feature set that most content teams use day to day.

11. WangEditor

WangEditor is a Chinese open-source editor that has built a solid international user base since its v5 rewrite. It supports React and Vue out of the box, handles Chinese and multilingual content well, has a custom menu API, and the output is clean HTML. The GitHub repo is active and the documentation now has a full English version.

It’s an underrated pick for content-heavy applications where you need table editing, video embedding, and custom toolbar buttons without building them from scratch. If you need multilingual support or are building for a global user base with mixed language inputs, WangEditor handles edge cases that some of the more Western-focused editors don’t test for.

12. Lexical

Lexical is Meta’s open-source text editor framework, built to replace the aging Draft.js that powered Facebook’s comment boxes and composer fields for years. It ships as a lean core with a plugin interface, no toolbar, no rich-text features baked in, just the foundation, and you add exactly what your project needs from there.

The architecture is intentionally minimal, but Lexical attaches to a single contenteditable element and manages state through a set of modular packages you pull in separately, covering lists, links, tables, markdown support, and more.

It’s React-native and TypeScript-first, so it fits cleanly into modern stacks without adapters or wrappers. If you’re building something custom, a Notion-style block editor, a compact chat composer, or an AI-assisted writing tool, Lexical gives you the primitives to do it without fighting a WYSIWYG editor that wasn’t designed for that use case.

Conclusion

You’ve seen 12 open-source WYSIWYG editors that cover the full range, from low-level frameworks like ProseMirror and Slate.js for teams building custom editing products, to drop-in options like TinyMCE and Quill for projects that need something running the same day.

If you’re picking one today, start with TinyMCE if you want the most battle-tested option with the largest plugin ecosystem, TipTap if you’re in React or Vue and want full UI control, and Editor.js if you want structured JSON output instead of raw HTML.

Install one on a local test page this evening and have a working editor replacing a textarea inside 20 minutes.

Which of these are you using in production right now, and is there one you’d add to this list that didn’t make the cut? Drop it in the comments.
