Gecko layout engine

Gecko is a free web browser layout engine designed to support open Internet standards such as HTML 4.0, CSS 1/2, the W3C Document Object Model, XML 1.0, RDF, and JavaScript.

Gecko is being developed at mozilla.org (http://mozilla.org/). Gecko has been known previously by the code names Raptor and NGLayout.

Gecko offers a rich programming API (http://www.mozilla.org/projects/embedding/) that make it suitable for a wide variety of roles in Internet enabled applications, such as web browsers, content presentation and client / server. Primarily it is used for the Mozilla browser derivatives such as Netscape 6, but it is used elsewhere as well.

• Mozilla (Mozilla.org's own browser suite under the codename SeaMonkey)
• Netscape 6.0 and later versions
• Beonex Communicator
• IBM Web Browser for OS/2
• Aphrodite[?]
• Mozilla Firebird
• ActiveState Komodo (http://www.activestate.com/Products/Komodo/) visual development environment for Perl, Python and more on Windows and Linux
