Local DoH DNS Proxy Studio

A lightweight Linux desktop alternative to DNSCrypt-Proxy and Acrylic DNS Proxy
for local encrypted DNS-over-HTTPS resolution, response caching, domain filtering,
and resolver speed benchmarking. Independent open-source project, not affiliated
with, sponsored by, or endorsed by DNSCrypt or Acrylic DNS Proxy.

FEATURES
- Local DoH UDP Proxy & Live Query Log: binds a non-root local UDP DNS listener
(default port 5354) and forwards RFC 1035 queries over encrypted RFC 8484
DNS-over-HTTPS (application/dns-message) to Cloudflare, Google, Quad9, Mullvad,
or custom endpoints with an interactive DNS lookup tester and real-time query log.
- Domain Blocklist & TTL Response Cache: block exact domains and wildcard
subdomains returning 0.0.0.0, import or export plain-text blocklist files,
inspect cached records with live remaining TTL, and flush the cache in one click.
- DoH Provider Speed Benchmark: measure live wire-packet lookup latency
(min, average, max milliseconds, and success rate) across upstream DoH
resolvers and apply the fastest provider directly.
- Bilingual Interface: English default UI with instant Vietnamese translation toggle.
