Intra — Open Source Firewall App

Intra is an experimental tool that allows you to test new DNS-over-HTTPS services that encrypt domain name lookups and prevent manipulation by your network. It currently supports services from Cloudflare and Google, and additional options may be added over time. Features: * Built-in support for public DNS services from Cloudflare and Google * Visualization of server performance and application query behavior * Geocoding of query results to compare against expected regional results
