This includes the ~30 native Zap app integrations: https://zapier.com/apps/categories/zapier-tools
These are usually the most common/popular and critical Zap app integrations.
That is about 5% of the 5,000+ public Zap apps in the Zapier App Directory: https://zapier.com/apps
Yes, there are private Zap apps and invite-only Zap apps.
However, there is no public list available that lists these Zapier-owned Zap app integrations.
You can submit a ticket with Zapier Support to request this resource be made available for reference: https://zapier.com/app/get-help
While most apps on Zapier are built and maintained by the app developers themselves on the Zapier Developer Platform, Zapier keeps an internal list of app requests.
This is a common misconception.
If there is a bug, feedback, or feature requests related to a Zap app integration, those can be submitted via a ticket to Zapier Support to be logged: https://zapier.com/app/get-help
But, more often than not, the responsibility will fall on the app developer to update/upgrade their Zap app integration.
That means it can be more beneficial to submit requests to the app developer directly, rather than Zapier.
Q&A
Q: What is a Zapier-owned Zap app integration?
A: That means Zapier maintains the Zap app integration instead of the app developer. so Zapier would be in charge of fixes and improvements.
