Optimizing WebKit & Safari for Speedometer 3.0
The introduction of Speedometer 3.0 is a major step forward in making the web faster for all, and allowing Web developers to make websites and web apps that were not previously possible. In this article, we explore ways the WebKit team made performance optimizations in WebKit and Safari based on the Speedometer 3.0 benchmark. In order to make these improvements, we made an extensive use of our per
Implementing Vertical Form Controls
Safari 17.4 adds vertical writing mode support for form control elements across macOS, iOS, iPadOS, and visionOS. Setting written text vertically is commonly observed in East Asian languages.

Safari releases are development hell ★★★★★
Safari 16.4 rolled out last week, and for us it's been a nightmare. We make the browser-based game creation app Construct. Early versions of Safari 16.4 broke opening projects, previewing projects, and all existing content published with Construct, all in different ways. I wanted to share our experience so customers, developers, regulators, and Apple themselves can see what we go through with what

WebKit on GitHub!
On June 23rd, the WebKit project froze its Subversion tree and transitioned management and interaction with our source code to git on GitHub. Why git? git’s distributed nature makes it easy for not just multiple developers, but multiple organizations to collaborate on a single project. git’s local record of changes makes moving commits between branches or reverting changes simple and quick. git’s
Understanding Garbage Collection in JavaScriptCore From Scratch
JavaScript relies on garbage collection (GC) to reclaim memory. In this post, we will dig into JSC’s garbage collection system. Before we start, let me briefly introduce myself. I am Haoran Xu, a PhD student at Stanford University. While I have not yet contributed a lot to JSC, I found JSC a treasure of elegant compiler designs and efficient implementations, and my research is exploring ways to tr
