Bitly does have an integrations directory called the Bitly Apps and Integrations Marketplace. This page gives you access to a bunch of tools and services that can add functionality to Bitly links beyond just shortening.

The Bitly Apps and Integrations Marketplace has connections to Zapier so you can automate workflows and other 3rd party services to help manage, analyze and distribute links better. These integrations are designed to help you plug Bitly into your existing toolset so you can streamline social sharing, campaign tracking and data analytics for a more integrated digital strategy.

Bitly works with 45 app and integration partners. These partners give you a choice of apps that integrate with Bitly to make link management a whole lot easier.
