Echo1 was the first iteration of the Echo framework. It was initially released in 2002 and used quasi-AJAX capabilities to provide a component-based and event-driven means of developing web-based applications.

ECHO1 IS NO LONGER UNDER ACTIVE DEVELOPMENT. All source code and documentation remain available on this site. If you are developing a new application, it is strongly recommended that you use a newer version of the Echo platform, e.g., Echo3.

Documentation: Documentation resources for Echo1, including the Developer's Guide.

Download: Download Echo1 releases.

EchoStudio: EchoStudio 1.0 is available for rapid application development of Echo1-based applications.
