What is Instapaperpro group.com.instapaper?
~/Library/Group Containers/group.com.instapaper is a shared data folder created for Instapaper on macOS. Group Containers let an app and its related components use the same stored data, which can include synced reading lists, saved article metadata, downloaded content, and other working files the app needs across features. Users usually encounter this folder while reviewing Library storage or cleaning up leftover app data. If Instapaper is still installed and in use, this folder helps the app keep your reading environment consistent. If the app has already been removed and you no longer need its saved local data, the folder is generally only useful as leftover app data.

Safety overview
Status: Mostly safe
This is ordinary app data, not a system file. Deleting it can remove Instapaper’s locally stored information on your Mac, such as offline article content, sync state, or app-specific shared data, and the app may recreate the folder later if you keep using it. If you still use Instapaper, leave it in place. If you remove it, make sure anything important is already synced or exported first.
Recommendation: Keep this folder if you still use Instapaper on your Mac. If you have uninstalled Instapaper or no longer need its local reading data, you can remove the folder as part of cleanup, knowing that any Mac-specific offline data stored there may be lost.
