[Tool] NextDNS Blocklist Automator - Sync Custom Raw Lists Easily (100% Client-Side) | Upgrade Your Blocklist

Hi everyone,

As a long-time NextDNS user, I always loved the platform but found it tedious to manually import large, custom external blocklists (like Hagezi, OISD, or specialized RPZ lists) into my Denylist. Dealing with different formats, comments, and invalid domains was always a hassle.

To solve this, I built NextDNS Blocklist Automator. It’s an open-source, web-based tool that securely bridges external raw text lists to your NextDNS profile.

🚀 Key Features:

• Fault-Tolerant Parser: It automatically ignores comments, empty lines, and bad formatting. Just paste the raw URL, and it surgically extracts the valid domains.

• Broad Support: Understands 9 different formats natively (Adblock/uBlock, Hosts, Dnsmasq, RPZ, Wildcards, etc.).

• Privacy First (No Backend): This is 100% client-side. Your API Key and Profile ID never leave your browser. All requests are made directly to the NextDNS API.

• Premium UI: Features a macOS-style terminal log window, responsive design, Dark/Light mode, and multi-language support (EN, ES, RU, ZH, TR).

I built this to give back to the community. Feel free to use it, inspect the code, or contribute on GitHub. Any feedback or feature requests are highly appreciated!
