DryDock vs TestFlight: 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 TestFlight? iOS beta testing on the fly. With TestFlight, developers simply upload a build, and the testers can install it directly from their device, over the air.

DryDock and TestFlight can be categorized as "Beta Testing / Mobile App Distribution" tools.

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, TestFlight provides the following key features:

• Sessions- Discover how testers are using your application. Watch as they progress and take unexpected turns.
• Crash Reports- Reported in realtime, with environment snapshots and full session activity.
• In-App Questions- The most effective way to get tester feedback. Get the answers you need by asking questions the moment a checkpoint is passed.

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.
