GaiaEHR is free and open-source medical practice management and electronic health record software.

The software suite is written as a web application and includes both server and client.

The server is written in PHP and can be employed in conjunction with a LAMP "stack", though other operating systems are supported as well.

The client side does not employ a common web browser, but some own software based on the Ext JS JavaScript application framework.
