 ## Why Build a Plane App?
-Plane has a large ecosystem of users, build community integrations to highlight your product or service to the Plane community, or simply build an integration for your own internal requirements.
 
-Stop doing manual work. Plane integrations eliminate repetitive tasks like copying updates between tools, creating work items from support tickets, or generating status reports. Instead of spending hours on administrative work, let your integration handle it automatically.
