In iOS, iPadOS and macOS 26, you can now build robust content filters that make traffic decisions using the entire URL — not just the hostname — all without compromising privacy and security.

This can be a better alternative to the current local VPN filtering approach because it works with WireGuard/OpenVPN VPNs, and it works with the entire URL instead of just the domain.
Another famous iOS adblocker is also looking into this new API.

Proposed solution

Implement URL filtering.

We're working on it. There are some issues with the API at the moment though, it just does not work, but at some point in the future Apple will fix it :)
