I found out that Portmaster cannot reliably block ads on a web page level the same way Ublock Origin does.

Is there a free/opensource substitute for something like AdGuard. I was hoping Portmaster might be it but it is not suitable for web page level ad blocking. But great for blocking Windows telemetry.

I am still a bit confused about what you want to replace, and on which platform.

I use iodéOS on mobile, it’s got an adblocker and tracker blocker integrated into the OS, and after using it when I go back to Linux I’ve been longing for something like portmaster or zen. Has anyone tried both and can compare the two?

Never used Zen but it seems to be a DNS filter? Safing Portmaster offer additional functionality e.g. SPN & Firewall.
