Project mention: WebShield – A new wide-spectrum content blocker for Safari | news.ycombinator.com | 2025-02-28
Blink forked from Webkit more than a decade ago. There are tests that try to measure their compatibility, like https://wpt.fyi/results/?label=experimental&label=master&ali... (part of https://web-platform-tests.org/). They also have different JS engines these days (V8 vs JSCore).
That said, as a frontend dev, I very very rarely run into real world issues between Safari and Chrome. More often it's Firefox/Gecko that lags behind, usually in some sort of graphics optimization (SVG and canvas stuff). Also some differences in WebGL and webgpu support, but those are niche enough that it's not a big deal yet.

StarlingMonkey is a JavaScript runtime we’ve built together with our friends at Fastly and contributed to the Bytecode Alliance. It’s built on top of SpiderMonkey in a highly modular way, making it easy to configure as needed for our use case. Crucially, it comes with an implementation of key web APIs that substantially improve compatibility with the web ecosystem, like the fetch API for handling outgoing HTTP requests, key parts of the Service Workers spec for handling incoming requests, streaming processing of request and response bodies using the web’s Streams API streamssetTimeout, and setInterval.

My long-shot hope is that the page can come to embody most of the wiring on the page, that how things interact can be encoded there. Behavior of the page can be made visible! There's so much allure to me to hypermedia that's able to declare itself well.
This could radically enhance user agency, if users/extensions can rewire the page on the fly, without having to delve into the (bundled, minified) JS layers.
There's also a chance the just-merged (!) moveBefore() capability means that frameworks will recreate HTML elements less, which is a modern regression that has severely hampered extensions/user agency. https://github.com/whatwg/dom/pull/1307

> OPFS doesn’t come with graceful handling of concurrency out of the box. Developers should be aware of this and design around it.
There's a multiple readers and writers proposal [0]. It's been "position: positive" by Firefox [1], implemented in Chrome [2], and ignored by Webkit [3] (of course).
