Easy to setup within minutes. Comes with setup guides for all systems. You only need to enter two IP adresses.
An easy on-ramp to DNS-level ad and tracker blocking: point two IP addresses at it and you’re filtering across every device, no app required. Against NextDNS it offers less granular per-device customization, so power users who want detailed profiles may prefer the alternative. Pick AdGuard DNS when you want blocking running in minutes with minimal fuss, and you’re comfortable with a hosted service handling your queries. If deep configurability is the priority, look at NextDNS or a self-hosted option.
