Apple on Wednesday released Safari Technology Preview 147, the latest version of their developer preview web browser. The preview version of Apple’s popular browser offers developers and other interested users the ability to try out features that may or may not, debut in future public release versions of Safari.
The current Safari Technology Preview release is built on the Safari 16 update and it includes features coming in macOS Ventura. It adds support for Live Text in videos and images, new web technologies, web push Passkeys, improved Safari Web Extensions, and more.
The preview is available for both macOS Monterey and macOS Ventura. It is no longer available for macOS Big Sur.
Release 147
Safari Technology Preview Release 147 is now available for download for macOS Monterey 12.3 or later and macOS Ventura beta. Updates to Safari Technology Preview are no longer available for macOS Big Sur. If you already have Safari Technology Preview installed, you can update in the Software Update pane of System Preferences on macOS Monterey, or System Settings under General → Software Update on macOS Ventura.
Note: Shared Tab Groups and syncing for Tab Groups, Website Settings, and Web Extensions are not enabled in this release.
Many of the 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. Experience and test the HTML, CSS, JavaScript, and other web technologies that are available in Safari 16 Beta and included in previous Safari Technology Preview releases.
Web Push. Send notifications to people who opt-in on your website or web app with Safari Technology Preview on macOS Ventura betas.
Passkeys. Preview the new type of phishing-resistant credential that makes signing in to websites safer and easier. Available through Safari’s WebAuthn platform authenticator. To learn more about passkeys, see Meet passkeys.
Improved Safari Web Extensions. Test out API improvements including the ability to open a Safari Web Extension popover programmatically.
Web Inspector Extensions. Build custom tooling or convert existing developer tools extensions to use in Web Inspector.
Flexbox Inspector. Use the new visualization overlay in Web Inspector to help you more quickly and easily understand the layout of elements with Flexbox. It marks both the free space and gaps between flex items to reveal how they affect the result.
If you see bugs or unexpected behavior with the interface of Safari Technology Preview, please file feedback with Apple’s Feedback Assistant. If you come across an implementation bug in web technology, Web Inspector, or have a request, please file a ticket on the WebKit bug tracker.
While the preview is intended for use by developers and advanced users, in order to provide Apple with feedback on the development of the Safari browser, it can be run side-by-side with the release version of Safari. The app doesn’t require a developer account to download and install. For more information, visit the Safari Technology Preview website.
