UtilCraft
Browser-based dev tools that never upload your data anywhere
What it does
I built UtilCraft after getting frustrated with online tools that send your files and data to some random server. A JSON formatter shouldn't need an internet connection. A PDF merger shouldn't see your documents. Everything on UtilCraft runs locally in your browser, image compression, UUID generation, PDF merging, regex testing, hash generation, and more. 16 tools so far, all free, no account needed. Would love your feedback on what to add next.

- H6Homebrew 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!
