Ladybird Browser adopts Rust, with help from AI (ladybird.org)

Lobsters.

We’ve been searching for a memory-safe programming language to replace C++ in Ladybird for a while now. We previously explored Swift, but the C++ interop never quite got there, and platform support outside the Apple ecosystem was limited. Rust is a different story. The ecosystem is far more mature for systems programming, and many of our contributors already know the language. Going forward, we are rewriting parts of Ladybird in Rust.

However, if we’re talking about the WebKit-based Linux browsers (such as Konqueror), IIRC, they’re a bit out of spec when it comes to the “modern Web”: WebKit’s adoption of latest specs tends to be slower than Firefox and Chromium.

WebKit-GTK is up to date. 30 seconds of research in your favorite search engine and you would have found it out.

It takes the same 30 seconds of using caniuse.com (screenshot below), which doesn't list WebKit-GTK specifically, but lists Safari (which is WebKit under the hood), for it to become clear how many things are missing from Safari implementation (which is WebKit).

To be fair, yes, there are many bleeding edge features, some of them implemented only on WebKit/Safari, but those Safari-only features are kind of proprietary features (prefixed by -webkit-). Similarly, there are indeed many features still missing from Firefox while already implemented for the two other engines (such as CSS @function).

But my point, which I should've gone into further detail earlier,, is that WebKit, primarily maintained by Apple (originally authored by Apple, and a trademark of Apple since 2013), doesn't have the same, browser-focused teams found on Mozilla (whose main product is Firefox) and Google (whose main product is advertisement through their platforms, including Chrome, so Chrome is part of their main focus just because that's essential to keep the ads running and telemetry sneaking on the user). Apple is more focused on other businesses, such as hardware and UI, Safari and WebKit are their side-project.
