Yes, Servo is an embeddable web browser / webview, like Chromium Embedded Framework. (CEF)

Electron = Node.js + CEF

Tauri = Rust + webview

Tauri has an experimental branch to use Servo to provide a bundled webview. Currently it relies on a system-level webview, like Edge on Windows, Safari on MacOS, and webkit-gtk on Linux.

Thank you!
