Codynet is a free, privacy-first suite of browser-based network tools: DNS, DIG, MX, TXT, reverse DNS, a resolver comparison (Cloudflare/Google/Quad9/OpenDNS), TLS and HTTP-header checks, RDAP WHOIS, subnet calculator, and bulk lookups with CSV export. No signup, no query retention — structured output instead of raw dumps, with a plain-English guide on every tool.

Hey Product Hunt 👋 I built Codynet because every time I needed a quick DNS or cert check I'd land on a tool that wanted a login, kept my queries, or buried the answer under ads. Codynet is the opposite: fast, private, structured, and free — no signup, no query retention. My favorites are the DNS resolver comparison (run one query across Cloudflare, Google, Quad9 and OpenDNS side by side) and the RDAP-based WHOIS. Every tool also ships with a short plain-English guide. Would love your feedback — what tool should I add next?

Mid-launch note:

Codynet's live and totally free. No signup, no query retention. The DNS resolver comparison (Cloudflare / Google / Quad9 / OpenDNS in one shot) is the crowd favorite so far. What network tool do you wish existed but never does it cleanly? Taking notes for v2.
