Per-app firewall
Limit who can reach an app to the IP addresses you choose. It is off by default, so nothing changes until you turn it on.
Find it in the Firewall tab on the app page.
- An IP allowlist for each app
- An "Add my IP" button, so you do not have to look your address up
- "Allow Cloudflare" and "Cloudflare only" modes for apps behind Cloudflare
- Covers the app's address, its custom domain and its direct port
