What it does

BlazeDiff Agent auto-discovers your routes, captures deterministic screenshots, and runs pixel diffs locally. It hands a small region tile to Claude Code, Cursor, or Codex for a verdict, instead of you eyeballing 40 full-size PNGs. No SaaS. No API key. MIT. Built on N-API (Rust), WASM, and pure-JS diff cores: 3 to 4× faster than odiff, 8× faster than pixelmatch on 4K. Already used by Vitest, Shopify, Ant Design, Vega, and ApexCharts.

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!
