What it does

DomainBrief turns any domain into a shareable intelligence report in seconds. Type a domain, hit enter, and get WHOIS, DNS, SSL/TLS, HTTP headers, email auth (SPF/DMARC/DKIM), tech hints, BGP routing, health score, and 20+ more signals in one terminal-style brief. Every report gets a shareable URL and a public JSON API — no signup required. Built for developers, security teams, and founders who want fast domain research without juggling a dozen tabs.

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!
