Best Linux/UNIX HTML Editors

Komodo Edit is hands down the best free XML editor available. It also includes a lot of great features for HTML and CSS development. Plus, if that isn't enough, you can get extensions for it to add on languages or other helpful features (like special characters). It's not the best HTML editor, but it's great for what you pay, especially if you build in XML.

Aptana Studio community edition is an interesting take on Web page development. Instead of focusing on the HTML, Aptana focuses on the JavaScript and other elements that allow you to create Rich Internet Applications. One of the things I really like is the outline view that makes it really easy to visualize the DOM. This makes for easier CSS and JavaScript development. If you are a developer creating Web 2.0 applications, Aptana Studio is a good choice.

Screem is a versatile text Web page editor and XML editor. It recognizes the Doctype you're using and validates and completes tags based on that.

Aptana Studio professional edition is an interesting take on Web page development. Instead of focusing on the HTML, Aptana focuses on the JavaScript and other elements that allow you to create Rich Internet Applications. One of the things I really like is the outline view that makes it really easy to visualize the DOM. If you are a developer creating Web 2.0 applications, Aptana Studio is a good choice. The professional edition adds features like secure FTP, Internet Explorer JS debugging, JSON support, and customer service including one year of updates.

KompoZer is a good WYSIWYG editor. It is based on the popular Nvu editor - only it is called an "unofficial bug-fix release." KompoZer was conceived by some people who really liked Nvu, but were fed up with the slow release schedules and poor support. So they took it over and released a less buggy version of the software. Ironically, there hasn't been a new release of KompoZer in over a year.

Nvu is a good WYSIWYG editor. I prefer text editors to WYSIWYG editors, but if you don't, then Nvu is a great choice, especially considering that it's free. I love that it has a site manager to allow you to review the sites that you're building. It's surprising that this software is free. Feature highlights: XML support, advanced CSS support, full site management, built-in validator, and international support as well as WYSIWYG and color coded XHTML editing.

SeaMonkey is the Mozilla project all-in-one Internet application suite. It includes a Web browser, email and newsgroup client, IRC chat client, and composer - the Web page editor. One of the nice things about using SeaMonkey is that you have the browser built-in already so testing is a breeze. Plus it's a free WYSIWYG editor with an embedded FTP to publish your Web pages.

Komodo IDE is a great tool for developers who are building more than just Web pages. It has support for a wide variety of languages including Ruby, Rails, PHP, and more. If you're building Ajax Web applications, you should take a look at this IDE. It is also great for teams as there is a lot of collaboration support built-into the IDE.

Amaya is the W3C Web editor. It also acts as a Web browser. It validates the HTML as you build your page, and since you can see the tree structure of your Web documents, it can be very useful for learning to understand the DOM and how your documents look in the document tree. It has a lot of features that most Web designers won't ever use, but if you're worried about standards and you want to be 100% sure that your pages work with the W3C standards, this is a great editor to use.

EditiX Lite is a free version of EditiX for non-commercial use. If you need to manipulate XML or XHTML, this is a fine product. You can use it to write valid XHTML documents, but it's major strength is in the XML and XSLT functionality.
