cwbrowser - A Zig-built browser engine passing Acid3 with 100/100
Show HN: I worked on a new browser for 2 years, today it passed Acid 3
cwbrowser is a groundbreaking web browser featuring a rendering engine written entirely from scratch in Zig, paired with Google's V8 for JavaScript execution. Developed over two years of solo engineering, this lightweight engine bypasses Chromium, WebKit, and Gecko to deliver performance roughly twice as fast as Chrome in early benchmarks. It achieves a perfect 100/100 score on the Acid3 conformance test, proving that a modern, standards-compliant browser can be rebuilt to be smaller, faster, and fully understandable by a single developer. A macOS preview for Apple Silicon is coming soon.
The result is a browser small enough to reason about end to end, and fast enough to beat the mainstream engines on the same hardware.
