2022-04-22 Update: Out of an abundance of caution due to the legacy nature of the app, we have moved up the deprecation timeline and the shutdown is effective immediately.
The Pull Panda and Pull Analytics services will be shut down on June 21, 2022. In the past year since shutting down Pull Reminders and Pull Assigners in favor of code review assignment and scheduled reminders, there has been a significant decrease in the usage of the remaining Pull Panda features.
While there are not immediate replacements for all of the Pull Analytics features, work is underway to incorporate analytics features natively into GitHub. The recently released Insights features for the new projects experience is a first step in this direction, and more features will be released in the future.
If you have any feedback about code analytics features that GitHub should support natively, please join in the discussion.
