Apple has rolled out a fresh update to Safari Technology Preview, its experimental browser built to test upcoming web features. The program first launched in March 2016, and since then, it has served as a public testing ground for tools that may later arrive in the standard Safari browser.

With Safari Technology Preview 238, Apple is refining a wide range of core web technologies. The update delivers fixes and improvements across Animations, CSS, Editing, Forms, Networking, Rendering, Scrolling, SVG, Web API, Web Inspector, WebAssembly, and WebRTC. As a result, developers get a more stable environment to test modern web apps and advanced browser functions.

Importantly, the current Safari Technology Preview release supports machines running macOS Sequoia and macOS Tahoe, the latest versions of macOS. This ensures compatibility with Apple’s newest desktop software and hardware ecosystem.

Users who have already downloaded Safari Technology Preview from Apple’s website can install version 238 through the Software Update feature in System Preferences or System Settings. Apple has also published full release notes on the Safari Technology Preview website, giving developers a detailed breakdown of changes and fixes.

Apple created Safari Technology Preview to collect real-world feedback during the browser development cycle. By opening early builds to both developers and everyday users, the company can test new web technologies before pushing them to the main Safari release.

Notably, Safari Technology Preview runs side by side with the regular Safari browser. Users can experiment with new features without affecting their primary browsing experience. Even better, Apple does not require a developer account to download or use the preview browser, which lowers the barrier for testing and feedback.

Over time, this public testing strategy has helped Apple fine-tune Safari’s performance and standards support.
