Self-Hosted applications are services that you run securely from home, or on your personal server. Self-hosting these applications gives you total control of your personal data.
Heimdall is a quick and easy way to organize all of your applications and frequently visited links into one page.

Once you add your application to the dashboard through its easy to use interface, you can drag and drop to move the buttons around as you see fit.
