GoKawiilLadybird browser adds Twitch video playback, CSS scroll snap, and Rust-based rendering
The Ladybird browser project shipped a major August update that adds video streaming support for Twitch and more YouTube formats through expanded Media Source Extensions codec support, plus CSS scroll snap, JavaScript debugging tools in DevTools, pausable downloads, and session restore. The team also shifted focus toward performance, introducing a new style engine, layout caching, off-main-thread CSS animations, and moving CSS parsing and painting pipelines to Rust for safety.
GoKawiil's interpretation of the reporting above, not reported fact.
These updates show Ladybird maturing from a novelty open-source browser project into one capable of handling mainstream streaming and modern web features that most sites now depend on. The move to Rust for core rendering components and new sponsorship funding suggest growing technical rigor and financial sustainability for an independent browser engine trying to compete outside the Chromium and Firefox ecosystems.
- Ladybird now supports Twitch streaming and additional YouTube video codecs via improved Media Source Extensions.
- New CSS scroll snap and JavaScript debugging tools bring the browser closer to modern web standards compliance.
- Core components like CSS parsing and painting are being rewritten in Rust as part of a broader performance and safety push.
Programming Rust (O'Reilly) by Jim Blandy — Ladybird just moved its CSS parsing and painting pipeline to Rust, and this O'Reilly guide is the classic deep dive into the language's ownership, concurrency and systems-level features. If reading about a browser engine rewritten in Rust makes you want to try it yourself, it's a great desk companion.
