If they didn’t have the nodejs dependency then the Tauri bundle could be as small as 20mb.

Another pro not mentioned is that native integrations (i.e. obj-c on macos) are much easier to do since rust has great ffi integration with other native libraries.

The biggest pro to electron is that it has extensive plugins that are often widely used in production by large companies. But Tauri is definitely winning and any new project should use Tauri no matter what essentially.
