What it does

JSONKit is a free collection of 47 browser-based JSON tools built for developers. Format, validate, minify, diff, and convert JSON to CSV, YAML, XML, TypeScript, Go, Python, Kotlin and more - all running locally in your browser. No upload. No login. No data sent anywhere. Works offline after first visit. Paste real API keys and production tokens without worry — we literally cannot see them.

  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!
