DomainDetails.com - Free & Private WHOIS

What it does

Domain Details is a local-first way to look up any domain’s registration info while keeping your queries on your device. No accounts and no lookup data stored. Paste a domain and get instant WHOIS, RDAP, DNS, and registrar details. It’s free and includes powerful tools like a Chrome extension, MCP server, npm packages, and a public API. In a rush? Just paste domaindetails.com/ anywhere in front of your URL and get instant results.

Free private domain lookup using RDAP & WHOIS. Check registration, ownership, expiration, DNS records, and marketplace availability. Local-first, no tracking.

The domain you want isn't available. The owner won't reply. It's not listed on any marketplace. Just a parked page. We check it four times a day and email you within minutes of detecting a WHOIS, DNS, ownership, expiry, or marketplace-listing change. Your first watched domain is free. The moment a watched domain changes hands, drops in price, or shows up on a marketplace — you get an email. No checking back. Your watchlist follows you. Add a domain from your phone, check the history on your laptop. Every change to every watched domain, kept for 90 days with visual diffs — including aftermarket price drops. Your launch name is parked. We'll tell you the second it frees up. Watch expirations,…from domaindetails.com

  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. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
