Best Free and Open Source HTML Editors

SeaMonkey – all-in-one internet application suite

SeaMonkey is an internet suite. It’s the continuation of the former Mozilla Application Suite, based on the same source code, which itself grew out of Netscape Communicator and formed the base of Netscape 6 and Netscape 7. It contains an Internet browser, email & newsgroup client, HTML editor, IRC chat and web development tools.

SeaMonkey’s powerful yet simple HTML editor offers dynamic image and table resizing, quick insert and delete of table cells, improved CSS support, and support for positioned layers. For all your documents and website projects.

SeaMonkey is free and open source software.
