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 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.

  • Create complex code quickly.

  • Seamless Photoshop integration.

What We Don't Like
  • Tool options can be overwhelming.

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.
