Codynet

What it does

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.

DNS, RDAP, HTTP, TLS, and subnet investigations — deterministic, free, with transparent privacy limits. Packet-level DNS queries with raw output, sections, flags, and TTLs. Popular lookups: online nslookup tool , MX record lookup , online dig tool , TXT record lookup , reverse DNS (PTR) lookup , and DNS lookup . Not sure which tool you need? Start from the job you're doing. Run the same record across Cloudflare, Google, and Quad9 to see who has the new answer yet. Confirm MX routing, then read SPF, DKIM, and DMARC in the TXT records that authenticate mail. Inspect the certificate chain, expiry date, names, and trust before users hit an error. Follow redirects and review HSTS, CSP, and the…from codynet.com

  DN$ – an innovative, ad-supported DNS resolver2024 · github.com · ▲294

  Tired of companies snooping through your DNS traffic? Don't you wish you could get advertisements with your DNS records? Today we're introducing the innovative, privacy-focused, ad-supported DNS resolver - DN$!

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
