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. Also Read: 50+ Open Source Android Apps When You Want to Ditch Google
