5+ Best Open Source HTML Editors

Do you create web pages on HTML and want to use open source software? Check this list of the best Open Source Html Editors.

The only thing you need to create web pages and apps is a simple plain text editor and your imagination. The notebook itself or similar that comes with Windows serves us correctly. However, it is always good to have the support provided by specific specialized tools.

The most powerful ones offer all kinds of contextual help so that you don't have to remember every detail of the hundreds of CSS attributes and available HTML tags, a preview of the pages you are creating, browser support, tag validation, accessibility verification, and many other advanced issues.

Within the myriad of available tools, I will highlight some of the best open source HTML editors that are free, and I have used before, although there are many more and it is not an exhaustive list.

So let's see the best Open Source Html Editors that you can download for free to start creating excellent web pages.

Microsoft Visual Studio Code has been deemed as the best open source HTML editor for web development

Visual Studio Code is a popular Microsoft code editor and is completely open source.

Visual Studio Code was among the first ‘peace offerings' from Microsoft to Linux and the Open Source world. Microsoft has opened a good number of its tools after that. Of course, that does not include Microsoft Office.

Visual Studio Code is an excellent HTML editor, especially for web development. It is light too. Some of the other main features are:

5. BlueGriffon


This excellent open source HTML editor uses the Firefox rendering engine below to visualize the pages as you edit them. It has code writing aids (such as the “bread crumbs” on the bottom or access to the hierarchical structure of the page), and even offers the possibility to test CSS3 3D transformations in real time without leaving the editor (advantages of using the Mozilla Gecko engine).

It is free, Open Source and multiplatform (Windows, Mac, and Linux) and are available in several languages. The latest version is from almost a year ago, but the project is still active.

6. Notepad ++

It is free and also Open Source HTML editor although it only works under Windows. BlueGriffon has a multitude of plugins to extend its functionality, and as it is trendy, there are many to choose from. Notepad++goes much further than the notebook as it offers colored syntax, code structuring (to be able to fold and unfold zones covered by labels), support for many other programming languages, etc. It is good to have it on hand for testing or fast editions. It is one of my favorites.

7. Aptana Studio

Aptana Studio is another free multiplatform open source HTML editor. It offers excellent contextual help when writing HTML code, which also includes the support of different browsers for each feature.

Only because of this is it worth it. It has advanced features for programming with JavaScript and also supports multiple server languages, such as PHP, Python, and Ruby on Rails. It is based on Eclipse, and therefore on Java, so keep that in mind if you don't like to install that platform on your computer (due to its many security problems and slowness).
