Safari Technology Preview is an experimental browser version launched by Apple, mainly aimed at developers and advanced users. It is used to test new features and technologies that may be added to the Safari browser in the future, and is more frequently and cutting-edge than the official version.

Why is there a Safari Technology Preview?
As Apple continues to improve the Safari browser, it needs a platform to verify the feasibility and stability of new features in advance. Safari Technology Preview is such a "testing ground". It allows developers to test, feedback questions before the new features are officially launched, and even help web designers adapt to future changes in advance.
Common uses include:

- Test new web standards (such as JavaScript API, CSS features, etc.)
- Experience the features that may be added to Safari in advance
- Help Apple collect bug reports and performance data
What is the difference between Safari Technology Preview and the official version?
The biggest difference between the two is the update frequency and stability expectations .
Comparison items | Safari official version | Safari Technology Preview |
---|---|---|
Update frequency | How many times will be updated with macOS every year | Updated multiple times a month |
stability | Fully tested, suitable for daily use | There may be bugs or crashes |
Function | Current stable function | Includes experimental functions |
Installation location | Default installation | Need to download and install separately |
You can think of it as a "development preview" of Safari, a bit like the beta version of iOS, but specifically targeting the browser itself.

Who is suitable for Safari Technology Preview?
Although anyone can download it, the most suitable user is:
- Front-end developer : I want to test how new web technologies perform in Safari as soon as possible
- Web Tester : Check if the website is compatible with future versions of Safari
- Technology enthusiasts : I like to try something new and willing to tolerate occasional minor problems
If you just go online to watch news and browse social media on a daily basis, it is not recommended to use TP (Technology Preview) as the main browser.
How to install and use it?
Installation is actually very simple, the steps are as follows:
- Go to the Safari Technology Preview download page on Apple's official website
- Click to download the dmg file
- After installation, you will see a blue icon with the name Preview Safari browser
- After startup, you can open the web page normally, or you can open the developer tool for debugging.
Tips:
- It does not conflict with the official version of Safari and can coexist
- If you are not a developer, it is recommended to only open it when needed to avoid instability affecting the experience
- It will not be updated automatically, and every new version requires manual download and installation
Basically that's it. If you want to know whether a specific feature is already supported in TP, you can directly check the version update log in Apple's release instructions.
