7 Best WYSIWYG HTML Editor Open Source

by Anurag Roy

There are two kinds of code editors – Simple text-based editor and WYSIWYG (what you see is what you get). In our previous article, we discussed some of the best Open Source HTML Editor where you manually type in the code. While there are no issues with the text-based HTML editors, they are none the less old-school. And that’s where WYSIWYG HTML editor open source comes in. WYSIWYG HTML editors provide visually based options to build a website without any programming knowledge (remember the Wix Ad, that’s wizzy-sig)

WYSIWYG HTML editor has several advantages over the text-based editors. To start with, you can build a website with WYSIWYG editors even if you don’t know how to code. All you have to do is drag and drop items in the editor and once you are done, just copy the code. However, finding a good open source WYSIWYG HTML editor can be a chore. This is where we come in.

1. Pell

Pell is probably the smallest and simplest WYSIWYG editor that you will ever come across. It is literally 1.38 kb in size!

It offers all the basic functionalities and formats like headings, bold, italic, lists, quotes, links, and images. Other available actions include indentation, superscripts, subscripts, and font name and size. After you are done writing and formatting with Pell, it will output the whole HTML code which you can then simply copy and paste on your website or page and you’re good to go.

  • No dependencies
  • Easily customizable

Considering its size, Pell makes a compelling package. But let’s be honest, you can only get basic HTML files done with the limited editing options. So, if you are someone looking for a fast and light-weight WYSIWYG editor that’s open source for some very basic work, definitely check out Pell.

OpenWYSIWYG is a cross-browser rich-text HTML editor coded entirely in JavaScript. By just copy-pasting a few lines of code, you can turn any <textarea> into OpenWYSIWYG’s robust WYSIWYG HTML editor.

The UI and editing options with the drop-down menus are very similar to that of any text editor and you will feel right at home. Apart from all the basic formatting options, OpenWYSIWYG boasts of an enhanced color picker with 216 web colors to choose from and a powerful table formatting tool with every option you could think of.

Another great thing about OpenWYSIWYG is that along with all the visual options, you can still view raw HTML code and make adjustments directly in the code. Useful for when you want to learn or refresh your coding skills.

4. Jodit

Jodit is another fast and lightweight WYSIWYG HTML editor open source editor that you can embed in your code and start editing your page. It is quite light at around 100 KB in size and has been written completely in TypeScript. That’s why you don’t need any dependencies or libraries to run it.

It comes with a drag-n-drop interface for the image too. You can also attach YouTube or Vimeo videos via a link or embed them. The best thing I like about Jodit is that it comes with an ACE editor out of the box and with a single button, you can switch between the actual code and the preview mode.

5. Summernote

Summernote is a super simple WYSIWYG editor open source built on jQuery and based on Bootstrap. Since it supports Bootstrap, you can use all the supported styles and themes on your editor from Bootswatch.

The WYSIWYG HTML editor open source itself has a very clean and minimal UI and you can even edit out or add formatting options according to your need. With Summernote’s Air-mode, you can hide the whole toolbar and edit your document on the fly. Convenient. It can also automatically convert all images to base64, so you do not have to do image handling at all.

To me, the best part about Summernote is the hardworking team of developers behind it who are always listening to the community and adding new features. Examples include support for plugins and a lite or vanilla version of Summernote which doesn’t require Bootstrap.

Summernote visual editor


  • Minimum learning curve
  • Air Mode for on the fly editing
  • Supports Bootstrap 3.x.x to 4.x.x

Summernote is probably the most feature-rich but free and open source WYSIWYG HTML editor available in the market and it is constantly improving. If you are working with Bootstrap, then Summernote is a no brainer but even if you aren’t, Summernote deserves to be checked out.

Some of them include an advanced image editor, emoticons, spell checker, and it’s easy to even create your own plugin. All the tools can also be accessed with the inline editor which is extremely convenient.

Like TinyMCE, Froala is available in a lot of flavors, but even the free version packs plenty of punch. The only difference is that you won’t be getting the full source code and technical support.

  • Lightweight powerful editor

Froala is fast and lightweight with a beautiful UI but still manages to bring all the features one might be looking for in a WYSIWYG HTML editor. If you are okay without the source code and support, the free version will serve you just fine, else you know what to do.
