Apple today released a new update to Safari Technology Preview, the beta browser that Apple first introduced in March 2016. Apple designed the Safari Technology Preview to test features that might be introduced in future versions of Safari.

Safari Technology Preview feature
The current Safari Technology Preview build is built on the Safari 16 update and includes features coming in macOS Ventura. It adds support for live text in videos and images, new web technologies, push web passkeys, improved Safari Web extensions, and more, with Apple notes below.

Several new Safari 16 features are now available in Safari Technology Preview 147:

  • live text. Select and interact with text in videos or translate text in images on the web in macOS Ventura betas on Apple Silicon-based Macs.
  • web technologies. Experiment with and test the HTML, CSS, JavaScript, and other web technologies available in Safari 16 Beta and included in previous Safari Technology Preview releases.
  • web push. Send notifications to people who have signed up for your website or web app with Safari Technology Preview on macOS Ventura beta.
  • pass keys. Preview the new type of anti-phishing credential that makes logging into websites safer and easier. Available through Safari’s WebAuthn Platform Authenticator. To learn more about passkeys, see Meet passkeys.
  • Enhanced Safari Web Extensions. Test API improvements including the ability to programmatically open a Safari Web Extension popup.
  • Web Inspector Extensions. Create custom tools or convert existing developer tools extensions for use in Web Inspector.
  • Flexbox Inspector. Use the new visualization overlay in Web Inspector to help you faster and easier to understand the layout of elements with Flexbox. Defines both free space and gaps between flex items to reveal how they affect the outcome.

Shared tab groups, sync for tab groups, website settings, and web extensions are not enabled in this version.

The new design of Safari Technology Preview is compatible with devices running macOS 13 Ventura, unlike previous versions of Safari Technology Preview. According to Apple, Safari Technology Preview updates are no longer available for macOS Big Sur.

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

With ‌Safari Technology Preview‌‌, Apple aims to collect feedback from developers and users about the browser development process. Safari Technology Preview‌ can run alongside your existing Safari browser, and while it is designed for developers, it does not require a developer account to download it.
