Echo2 (Archived)

Echo2 is no longer under active development. We strongly recommended to use a newer version of the Echo platform, e.g., Echo3.

Echo is a platform for building web-based applications that approach the capabilities of rich clients. The applications are developed using a component-oriented and event-driven API, eliminating the need to deal with the "page-based" nature of browsers. To the developer, Echo works just like a user interface toolkit.

Echo is open-source software, licensed under the Mozilla Public License.
