Amaya (formerly Amaya World) was a free and open source WYSIWYG web authoring tool with browsing abilities.
It was created by a structured editor project at the INRIA, a French national research institution, and later
adopted by the World Wide Web Consortium (W3C) as their testbed for web standards; a role it took over from the Arena web browser. Since the last release in January 2012, INRIA and the W3C have stopped supporting the project and active development has ceased.
Amaya has relatively low system requirements, even in comparison with other web browsers from the era of its active development period, so it has been considered a "lightweight" browser.
It's a integrated fusion between Internet Explorer and Netscape.
It might be unknown if it's a web editor or a original browser.
