Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced in March 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.

Safari Technology Preview release 163 includes bug fixes and performance improvements for Web Inspector, Masonry Layout, CSS Custom Properties, Media Queries, CSS, Forms, Rendering, JavaScript, WebAssembly, Gamepad API, Web API, WebGL, SVG, Scrolling, Media, Accessibility, WebDriver, Safari Web Extensions, and more.

The current Safari Technology Preview release is version 16.4 and is compatible with machines running macOS Ventura and macOS Monterey.

The Safari Technology Preview update is available through the Software Update mechanism in System Preferences or System Settings to anyone who has downloaded the browser. Full release notes for the update are available on the Safari Technology Preview website.

Apple's aim with Safari Technology Preview is to gather feedback from developers and users on its browser development process. Safari Technology Preview can run side-by-side with the existing Safari browser and while designed for developers, it does not require a developer account to download.

Apple used to offer Safari for Windows. Since they are (supposedly) being forced to allow other rendering engines on iOS, maybe now would be a good time for them to make Safari cross-platform again...
I hope so. Most iOS and Mac users around me use Chrome on their iPhones and Macs. Chrome already ruled Windows and Android, so locking Safari engine on iOS is pretty much the only last holdout from making the whole internet to be "Chrome-based."

Same, and I don't get it. It's just the web...what does Chrome *really* do that Safari doesn't? Aside from consuming incredible amounts of memory, that is...

It's called habit/familiarity.
Chrome got a huge following back in the days (when Chrome was actually a great browser, fast and lean, compared to IE6). Most people simply stick with it to the point they equivalent the internet with the Chrome icon. Majority of people on Windows have even trained themselves to just install Chrome as the first thing they do on a new machine (even with MS Edge being Chromium based today). Naturally, when they are on a different system, ie Macs or iPhones, they will do the same, install Chrome due to the familiarity of the brand/icon as their go-to browser.

Apple shoot themselves in the foot when they ditched Safari for Windows. Ironically, Apple made Safari for Windows before Chrome even existing. If Apple would've stood by it, kept Safari on Windows, the story might be different today.

Also, Safari for iPadOS should play videos on native player. Very bad experience with custom web sites players. Can be an option.

I think the most interesting part are the number of changes being done to bring Webkit into alignment with the standards - hopefully that should mean that we're slowly moving away from having websites that work better on Firefox/Chromium than they do on Webkit based browsers. Regarding Webextensions, although new features aren't being added at a fast pace, there is a lot of conversation behind the scenes standardising the Webextension API with the Declarative Net Request particulars still being thrashed out as content filtering/blocking extension developers have been weighing into the Webextensions API meetings about the problems with the current setup. It'll be interesting to see what WWDC bring - features are are being worked on but aren't ready for the Technology Preview.

JavaScript for one. I run into issues about once a week where Safari won't display something. Have to use Firefox or Chrome for it to run properly. I wish I could only use Safari!! It got a lot worse with my first M1. That was 4-M1's ago 🤣🙄😂

I can take a brand new Mac out of the box, open Safari, and go to the Nike website (Apple Card 3% partner btw) and start scrolling through shoes. Eventually the images for shoes will stop loading for ones that have multiple color options so you just see a website sprinkled with pictures and blank white boxes. You have to scroll over the empty box for it to populate an image.

This is the most basic thing and Safari can’t get it right and hasn’t for a long time. However, Safari Tech Preview does for some reason. I’ve tried on Apple store computers and my own and it always fails.

Yes, infinite/lazy loading has been an issue for a very long time, another reported issue completely ignored. (You have it in the experimental features list ticked, in case you wish to try disabling/enabling, though we've tried and its worthless)
Imagine 2023 and CSS outline doesn't even support border-radius, even though it does since a few versions in STP, but the pace with which they implement to stable is beyond bizarre. Then they trash devs as if they all loved to support Chrome only, being the data-mine garbage it is, instead of significantly improving Safari 🤷🏼‍♂️.

The problem is Chrome works and works well. I read all this stuff about how people are jumping off of Chrome to FF or whatever but then I look at the stats and FF market share keeps shrinking and Chrome stays the same.

So many websites like this.

Chrome used to work well. But now it’s literally the new IE. It forces itself to people because so many web devs only test on Chrome for compatibility. Add on to people have their habits built up through time, people use Chrome now because it’s Chrome.

And we are entering the new dark age of internet, where the whole internet will be Chrome-based. Once iOS is opened for other web engines, web developers no longer has a reason to test compatibility with Safari. They would just tell their visitors to install Chrome.

Google’s own services already don’t work with other Chromium based browsers. Eg Google Docs, Sheets, etc don’t work with Brave. I have to use Safari, but that’s because WebKit is enforced on iOS, so Google would have to support it. Once that restriction is gone, Google can simply drop Safari from their supported browsers.

Having to keep going to FF to fill in forms or see pages that Safari won’t render or respond to. meanwhile the out of memory or low power messages are appearing more often. which is amazing since I am using a well loaded Mac Studio.

Finally the Javascript engine has been updated to support ES2018 Regex Lookbehind Assertions which broke lots of sites that assumed WebKit supported a nearly 5 year old standard (it looks like it was some heavy lifting) It was a noticeable compatibility gap that every other browser supported and broke sites like this

Same here, 16Gb RAM and always get the low on memory or this page is using resources and asking me to close the page. Never happened before Ventura.
Many times on facebook, the page won't scroll down and I have to re-load the page.
Really infuriating
