We (GitButler) however keep running into packaging issues that make all but a very small handful of linux distros "usable". There are also numerous papercuts that we keep getting due to Tauri being comparably less mature.
We've been making steps towards moving away from Tauri. We now already have the capability to run our rust backend as a web-server and use the frontend in a regular browser. One of the next steps is to package the frontend into an electron app, and run the web-server as a sidecar process.
While there may be size downsides to packaging an entire browser - size isn't really a big issue compared to the program simply not working on a large user demographic.
Philosophically, it also optimizes something that doesn't really matter much in 2025, download and disk space - despite the perceptions, the system Webview usually uses the same order of magnitude memory as Electron; maybe a little less, but not a Lot less. We can see the WhatsApp rewrite on Windows to use WebView2 as evidence of that.
The one time that Tauri is legitimately better though, is if you've got a lot of Rust code that you want to integrate - GitButler for example uses Tauri and it works for them because they have a lot of Git systems code and it's all in Rust.
