What is ZeroDot1s Whitelist Generator?

ZeroDot1s Whitelist Generator is a free, browser-based tool that creates firewall whitelists and DNS allowlists from simple domain lists. It exports to multiple formats including FortiGate CLI, pfSense aliases, Pi-hole regex, Sophos, and AdGuard Home.

Is my data uploaded to servers?

No, ZeroDot1s Whitelist Generator runs entirely in your browser. All processing happens client-side - no domain data is ever uploaded or stored on external servers.

What firewall systems are supported?

Supported formats include FortiGate CLI commands, pfSense alias import, Pi-hole regex blocklists, Sophos XG/UTM FQDN lists, AdGuard Home DNS syntax, and generic plain text lists.

How do I add custom presets?

Add your domain list as a .txt file to the WLS folder, then run node build.js to regenerate the presets manifest. The new preset will appear automatically in the Generator interface.

What input formats are supported?

The tool accepts plain text files with one domain per line. It automatically handles comments using # or /, empty lines, section labels ending with :, and wildcard domains starting with .
