Zimbra Desktop vs. Shift

Zimbra Desktop is a free and open source email client application that gives you online and offline access to all your email accounts in one place. Zimbra Desktop works with many types of email systems to synchronize email, contacts and calendar data between users mailboxes in the cloud and local data stored on your computer disk.

Shift is a customizable browser built for people who live in their browser all day. Unlike standard browsers, Shift lets you drag and drop apps, bars, and controls to build a layout that actually matches how you work. Choose from 6 starter templates or build from scratch. Either way, you end up with a browser that fits your workflow, not the other way around. Whether you're a freelancer juggling clients, a remote worker managing multiple tools, or an entrepreneur running several projects at once, Shift gives you the flexibility to shape your digital workspace around your life.
