Ladybird Browser Posts

Video on Twitch and YouTube, CSS scroll snap, JavaScript debugging, session restore, and a serious push on engine performance with a new style engine.

Private browsing, browser profiles, undo/redo, geolocation, WebAudio, a faster compositor, and moving style and layout to Rust.

Download management, sandboxing, browsing history, DevTools storage inspection, media playback speed, GPU isolation, WebAssembly GC, and more.

Ladybird is changing how code enters the project as we prepare to ship a browser to real users.

Passing Cloudflare Turnstile, async scrolling on an out-of-process compositor, Media Source Extensions on by default, a WebAssembly JIT, native content blocking, the HTML parser in Rust, on-disk JS bytecode cache, CSS @container/@scope/subgrid, and more.

Inline PDF viewer powered by pdf.js, GTK4 frontend, browsing history, speculative HTML parsing, off-thread JS compilation, async DNS, CSS anchor positioning, and more.

Hand-written assembly interpreter, off-thread parsing, new regex engine, Mach port IPC, bookmarks, CSS if()/inherit()/@container/@function, style invalidation, and more.

Adopting Rust, text editing overhaul, performance work on YouTube and Reddit, ScrollTimeline, CSS @counter-style, SVG partial relayout, and more.

We're adopting Rust as our C++ successor language, and using AI agents to accelerate the transition.

Shifting focus to real websites, Gmail performance, site compatibility, painting architecture, IPC hardening, HTTP caching, media streaming, and more.

CSS features, media playback, JS performance, HTTP caching, GC leak fixes, and more.

WPT gains, rendering improvements, streaming fetch, media fixes, and more.

Progress across caching, media, Trusted Types, XPath, CSS, WebGL, and even first runs on Windows.

HTTP caching enabled by default, better CSS custom property handling, DevTools improvements, CSS Typed OM API advances, view transitions, and Trusted Types.

Google Sheets support, Gamepad API, Cookie Store API, CSS Typed OM progress, layout work in grid and inline formatting, and better grapheme cluster handling.

Google reCAPTCHA now passes, high refresh rate rendering, HTTP/3 support, Trusted Types progress, @property work and UTF-16 correctness fixes.

Notable WPT progress, CSS logical alias properties, counters on pseudo-elements, tech() in @font-face sources, Local Storage persistence, Geolocation, and progress on Windows support.

We’re officially tax-exempt, new JavaScript date parser, Clipboard APIs, Transferable Streams, and an in-house BigInt implementation with LibTomMath.

Big WPT gains alongside performance work, faster JavaScript function calls, Flexbox layout optimization, script-blocking style sheet handling, mix-blend-mode, and URLPattern.

Video fixes with very basic YouTube support, site isolation (process per origin), Settings UI refresh, background-blend-mode, and faster relayout from intrinsic size caching.

Block rendering until CSS is ready, OpenSSL and curl adoption continues, Firefox DevTools protocol support lands, and aarch64 Linux joins CI.

Major WPT progress, test262 (JS spec) improvements, early Google BotGuard support, new CSS properties, and better light/dark mode behavior.

WebGL arrives, home-grown crypto replaced with OpenSSL, WebCrypto API improvements, Canvas2D filters, smarter calc(), Switch input, and CSS font-variant features.

Temporal rewrite, early Swift experiments, vertical text, Web Crypto API progress, CSS nesting and transform updates, color() improvements, and Editing API work.

Expanding our Board, stronger test infrastructure, WebAudio fixes, CSS filter support, nesting @media on the way, clip-path shapes, and our first pizza ordered with Ladybird.

Bringing in a browser industry veteran to raise the bar.

Networking via curl, better audio through FFmpeg, improved emoji support, Skia font decoding, CSS Transitions and Cascade Layers, plus GPU-accelerated masks.

Ensuring that the OSS community has a seat at the table.

HarfBuzz text shaping and RTL, Skia powering SVG and 2D canvas, sticky positioning, drag and drop, retained display lists for faster scrolling, and console.table().

Launching a nonprofit, Web Platform Tests, Wasm, image format libraries, and more!

Co-founder Chris Wanstrath shares his thoughts.

Launching our 501(c)(3) non-profit.
