Komodo Edit and Komodo IDE

There are two versions of Komodo: Komodo Edit and Komodo IDE.

Komodo Edit is an excellent free XML editor. It includes many features for HTML and CSS development, and you can get extensions to add languages or other helpful features such as special characters. 

Komodo IDE is a polished tool for developers who do unit testing, debugging, and code profiling and who build more than web pages. It supports a wide range of languages including Python, PHP, Perl, JavaScript, HTML, CSS and more. If you build Ajax web applications, take a look at this IDE. It works well for teams because it has built-in collaboration support.

Komodo Edit is a free download. Komodo IDE offers several paid plans (and a 21-day trial) that include a single license plan, a plan for teams of up to five people, and one for a full site license for teams of 20 or more.

NetBeans

NetBeans IDE is a free Java IDE that can help you build robust web applications. Like most IDEs, it has a steep learning curve, but once you get used to it, you’ll be hooked. One nice feature is the version control included in the IDE, which is useful for people who work in large development environments. Use NetBeans IDE to develop desktop, mobile, and web applications. It works with Java 8, JavaScript, HTML5, PHP, C/C++, and more. If you write Java and web pages, this is a great tool.

Screem

Screem is a web development environment. This versatile text web page editor and XML editor does not provide a WYSIWYG display. You see only the raw HTML on the screen. However, Screem ​recognizes the doctype you use and validates and completes tags based on that information. It includes wizards and help that you don't always see on Unix software. Any language that can be defined by a doctype can be edited in Screem.

Bluefish

Bluefish is a full-featured web editor for Linux, Windows, and Macintosh. It offers a code-sensitive spell check, auto-completion of many programming languages including HTML, PHP, and CSS, snippets, project management, and auto-save. It is primarily a code editor, not specifically a web editor. This means that it has a lot of flexibility for web developers who write in more than just HTML, but if you’re a designer by nature, you might prefer something different.

Bluefish is relatively lightweight for a GUI editor. It is fast and can load hundreds of files within seconds.

Oxygen is a high-quality XML editing suite of authoring and development tools. It offers validation and schema evaluation of your documents, as well as various XML languages like XPath and XHTML. It’s not a good choice for web designers, but if you handle XML documents in your work, it is useful.
