Bitly is a link management and shortener platform.

Rebrandly is the easiest way to create and share branded links (short URLs using your own domain name).

Short.cm is a white label link shortener, which allows you to create short links on your own domain.

Create ready-to-share links on the fly. Zapier's URL Shortener spits out a simplified version of any link you throw its way. Pass that link to Twitter, drop it in an email, or send it along to any Zapier-connected app.
