💻cwbrowser Built From Scratch in Zig Passes Acid3 Test
A new browser engine written from scratch just passed a major test
TL;DR
cwbrowser, built entirely with the Zig language and Google's V8 JS VM, passes Acid3 conformance test with a perfect score. It’s twice as fast as Chrome on early tests.
A new web browser called cwbrowser has been developed from scratch using the Zig programming language over two years by a solo developer. The browser passed the Acid3 conformance test with a perfect score of 100/100, proving its compatibility and performance against established standards. This is significant for developers looking to understand or build lightweight, high-performance web engines without relying on legacy codebases like Chromium, WebKit, or Gecko. cwbrowser uses manual memory management, no garbage collector, and a hand-written HTML parser, CSS cascade, layout engine, and paint pipeline in Zig.
