Webview Versions
WebView2 (Windows)​
Tauri uses WebView2 which is based on Microsoft Edge and therefore Chromium. WebView2 can update itself, you are guaranteed a relatively recent chromium build on all Windows targets.
WebView2 is supported on Windows 7 and newer and comes preinstalled on Windows 11. On versions older than Windows 11 the installer generated by Tauri takes care of ensuring WebView2 is installed on the system.
WebKit (macOS, iOS, & Linux)​
Tauri uses WebKit on macOS (through WKWebView) and Linux (through webkit2gtk).
Interpreting WebKit Version Numbers​
Webkit version numbers are quite complicated, so below is some helpful information to understand them.
WebKit version numbers are made up of 5 segments and a numeric prefix indicating which OS WebKit is built for:
$(SYSTEM_VERSION_PREFIX)$(MAJOR_VERSION).$(MINOR_VERSION).$(TINY_VERSION).$(MICRO_VERSION).$(NANO_VERSION)
The numeric prefix is called the SYSTEM_VERSION_PREFIX and seems to be only present for macOS and iOS builds (not for Linux). Furthermore, if the last two segments are both 0 they can be omitted (so a version like 613.2.7.0.0 would be referred to as 613.2.7).
As an example, the WebKit version shipped with Safari 15.5 on macOS Monterey (12.x) has the version number 17613.2.7.1.8. You can interpret it like this:
SYSTEM_VERSION_PREFIX: 17MAJOR_VERSION: 613MINOR_VERSION: 2TINY_VERSION: 7MICRO_VERSION: 1NANO_VERSION: 8
Here is what the SYSTEM_VERSION_PREFIX values map to:
| macOS version | SYSTEM_VERSION_PREFIX |
|---|---|
| sdk=iphone* | 8 |
| 13.0 | 18 |
| 12.0 | 17 |
| 11.0 | 16 |
| 10.15 | 15 |
| 10.14 | 14 |
| 10.13 | 13 |
| 10.12 | 12 |
| 10.11 | 11 |
macOS & iOS​
On macOS, Tauri uses the webview that comes preinstalled with macOS since version 10.10 (Yosemite). It is considered a core component and is therefore updated with the regular OS updates. This means unsupported macOS versions do not receive WebKit updates.
To find the WebKit version used by WKWebView on your version of macOS you can use this command in the terminal:
awk '/CFBundleVersion/{getline;gsub(/<[^>]*>/,"");print}' /System/Library/Frameworks/WebKit.framework/Resources/Info.plist
WebKit Versions in Safari​
The table below maps an OS version to the corresponding WebKit Safari versions so that you can use sites like caniuse to figure out if a specific web platform feature is supported.

Linux​
The diverse nature of the Linux ecosystem means it is very hard to compile accurate information about WebKitGTK on the various distros. The table below is a very incomplete list of the most commonly used distributions and their WebKit versions. You should always check your distro's repositories for up-to-date information.

| Debian 11, Ubuntu 18.04 (with update), centos 8 (non-stream) | 2.32 | 612.1.6 | 15.0 |
