Web browsers come with every operating system, on every device and most people use them throughout their day. Kolab Now provides a world-class web application to access all its features from any browser.

The world's most popular webmail application

Kolab Now's web application is based on Roundcube, the world's most popular open source webmail application with over half a million installations known worldwide that serve millions upon millions of users every single day. In fact, Kolab Systems is the primary developer of Roundcube, so it works absolutely perfectly with Kolab Now.

Universal support

The Kolab Web Application works with all modern desktop and mobile browsers and relies only on standard HTML5 support. The choice of web browser is not dictated by the use of the Kolab Web Application nor are any browser plugins or Java runtimes required.

Secure

The Kolab Now web application has been written with security in mind, and has been audited for safety by security professionals.
