Amaya is a browser/authoring tool that allows you to publish documents on the Web. It is used to demonstrate and test many of the new developments in Web protocols and formats. Given the very fast moving nature of Web technology, Amaya has a central role to play. It is versatile and extensible and is available on Unix, Windows, and Mac OS X platforms. Amaya has a counterpart called Jig Saw which plays a similar role on the server side.
