Blocks ads, trackers, and telemetry at the DNS level -- before they reach any device. Works on every phone, TV, laptop, and smart home device automatically.

All DNS queries are encrypted so your ISP cannot see what sites you visit. Uses DNS over HTTPS (DoH) with your personal client ID.

Queries resolve directly from root servers -- no forwarding to Google or Cloudflare. No third party sees your complete query history.

Updated daily with known malware, phishing, and tracking domains. Blocks threats before they load.

If Harbor is ever unreachable, your devices automatically fall back to Quad9 so your internet keeps working. You will never lose connectivity because of us.

See your blocked stats, add custom rules, and whitelist any site in one click if something gets blocked that should not be. No support tickets, no waiting.
