I have a static front-end and a compute back-end on the DO App Platform. I’d like to put it behind a Cloudflare Zero Trust Tunnel. I created a Droplet and installed the Cloudflare docker and the tunnel is healthy.
My questions are-
- Do the App Platform deployments live on my VPC network?
- If so, how can I find their IP address?
- How can I turn off public access to App Platform apps? (static and compute)
We really like the ease of auto-deploy when the App Platfom is linked up to bitbucket- so I don’t want to have to build an image and host on a droplet.
Any thoughts or best practices are appreciated.

Hey!
If I remember correctly the DigitalOcean App Platform apps don’t live inside your VPC, so you won’t be able to get internal IPs or restrict access via VPC-level controls. That also means you can’t natively route App Platform traffic through your Cloudflare Tunnel the same way you would with a Droplet.
There’s a feature request open for this exact thing, VPC support for App Platform apps and managed services: 👉 https://ideas.digitalocean.com/app-platform/p/vpc-with-apps-droplets-and-managed-databases
Make sure to upvote it!
Until then, one workaround is to place your App Platform backend behind Basic Auth or IP filtering (via headers + app logic), and tunnel via a proxy Droplet using your Cloudflare tunnel setup, though that adds some complexity.
Hope this helps!
