    I built a search engine for all domains on the internet▲5

    Hi HN, I built DomainExplorer.io, a search and analytics tool that lets you explore newly registered and expired domains across all TLDs — updated daily. The idea came from my frustration how hard it is to search for registered/expired domains. I wanted a simple and easy-to-use tool with web UI where you could submit queries like: - Find all domains in .com and .net zones that end with "chatgpt". - Find all expired domains that have "copilot" substring in name (excluding .ai and .io zones) and their name is shorter than 12 symbols - Find all domains with "amazon" in name and that were…

    DotComBuddy – Generate and check domains with AI in one go▲8

    I tend to use AI to brainstorm domain names, but I kept wasting time pasting each idea into Namecheap to see if they were available. So I built DotComBuddy - it generates ideas (using DeepSeek V3 - switched from GPT-4o after realizing quality was just as good) and checks availability in real time via Name.com’s API. Built with Next.js and Vercel’s AI SDK, the app gives you a table of available domains with their price. 10 free searches to try it out, then $9/year (what I’d pay to never do this manually again). Sharing this for anyone else tired of switching tabs to check domains. Happy…

    Ldns.com – fast DNS lookups from the URL bar▲7

    I built LDNS because I'm constantly curious about domain names - who owns them, which nameservers they use, how they're configured, and what their DNS records reveal. I wanted a fast, easy way to investigate domains right from my browser without juggling multiple tools. LDNS runs entirely client-side using Cloudflare's DNS over HTTPS. Just type a domain and instantly see: All DNS records with clickable filtering RDAP/WHOIS data with registrar info and expiration dates Email security configuration (SPF, DMARC, MTA-STS, BIMI) Export options (JSON, CSV, BIND zones, PDF reports) Try it at…

    Namealong – Domain search that pairs your query with 4114 other words▲7

    Namealong takes your query, pairs it up with 4000+ other words, suffixes, and prefixes, and shows you available .com domains by checking the ICANN zone file. That's fast, but semi-inaccurate, so when you hover over or click on domain names, an additional WHOIS check is done to verify availability. If this all sounds familiar, Lean Domain Search used to do this exact same thing, but earlier this year they added .blog domains to the search results with no way to filter them out, making the tool basically useless for .com searches.

    Model Tools Protocol (MTP) – Forget MCP, bash is all you need▲9

    Recently I was trying to use an MCP server to pull data from a service, but hit a limitation: the MCP didn't expose the data I needed, even though the service's REST API supported it. So I wrote a quick CLI wrapper around the API. Worked great, except Claude Code had no structured way to know what my CLI does or how to call it. For `gh` or `curl` the model can learn from the extensive training data, but for a tool I just wrote, it was stabbing in the dark. MCP solves this discovery problem, but it does it by rebuilding tool interaction from scratch: server processes, JSON-RPC transport,…
