To create and edit custom tabs:	Customize Application

Custom tabs show custom object data or other web content embedded in the app. You can create any of these types of custom tabs.

• Custom Object Tabs: Custom object tabs (available only at an app level and not on subtab apps) show the data of your custom object. Custom object tabs look and function just like standard tabs.
• Web Tabs: Custom web tabs show any external web-based application or web page. You can design web tabs to include the sidebar or span the page without the sidebar.
• Visualforce Tabs: Visualforce tabs show data from a Visualforce page. Visualforce tabs look and function just like standard tabs.
• Lightning Component Tabs: Lightning component tabs make Lightning components available in the Salesforce mobile apps and in Lightning Experience. Lightning components aren’t supported in Salesforce Classic.
• Lightning Page Tabs: Lightning page tabs let you add Lightning app pages to the Salesforce mobile app and Lightning Experience navigation bars.

  In Salesforce Classic, Lightning page tabs don’t appear on the All Tabs page when you click . Lightning page tabs also don’t appear in the Available Tabs list when you customize the tabs for your apps.

Subtab apps support only web tabs and Visualforce tabs.

Delegated administrators who can manage specified custom objects can also create and customize tabs for those custom objects.

In Lightning Experience, Lightning page tabs, Visualforce tabs, and Lightning component tabs have a fixed, friendly URL structure of /lightning/n/customTabDevName.
