DryDock vs Fabric by Twitter: What are the differences?

What is DryDock? DryDock enables rapid-deployment of internal product releases on demand while remaining on a supported internal update track. DryDock is an open source iOS application that we built at Venmo to manage and install all of our internal builds, allow employees to download new experimental apps at any time and to easily share builds designed for a broader audience with their friends.

What is Fabric by Twitter? Mobile developer platform. Installing and managing a wide range of SDKs can be cumbersome and complex. Fabric solves this problem by combining all seven of our SDKs under one roof and organizing them into three Kits: the Crashlytics Kit, the Twitter Kit, and the MoPub Kit.

DryDock and Fabric by Twitter belong to "Beta Testing / Mobile App Distribution" category of the tech stack.

Some of the features offered by DryDock are:

• Rapidly share builds
• Install any version of the your app that you've ever released to the App Store.
• DryDock is built on the Parse backend to make it really simple (and free) for anybody to host their own version of DryDock.

On the other hand, Fabric by Twitter provides the following key features:

• Crashlytics Kit - The Crashlytics Kit gives you a best-in-class toolset to build robust apps: crash reporting, beta distribution, and mobile app analytics that are so easy to understand, we called them Answers.
• Twitter Kit - Bring the conversation happening around the world into your app. From Login, to sharing, to displaying Tweets natively in your app, the Twitter Kit makes social integration simple.
• MoPub Kit - The MoPub kit helps you turn your app into a business. Monetize your app with just a few lines of code, and optimize your advertising across multiple ad networks.

DryDock is an open source tool with 450 GitHub stars and 38 GitHub forks. Here's a link to DryDock's open source repository on GitHub.
