> I recently went the other way (started a project in Tauri, moved to Electron) because of frustration with rendering differences between the web views employed on different platforms.
This is our #1 frustration with Tauri. The OS-provided system webviews are not stable, repeatable, consistent platforms to build upon.
Tauri decided that a key selling point of their platform was that Tauri builds won't bundle a browser runtime with your application. Instead, you wind up with whatever your operating system's browser runtime is. Each OS gets a different runtime.
Sounds nice on paper, but that has turned into a massive headache for us.
Safari and Edge have super finicky non-standard behavior, and it sucks. Different browser features break frequently. You're already operating in such a weird way between the tight system sandboxing and CORS behaviors (different between each browser), the subtle differences are death by a thousand cuts. And it never seems to stop stacking up. These aren't small CSS padding issues, but rather full-blown application behavior breakages. Even "caniuse.com" is wrong about the compatibility matrix with built-in web views.
To be fair, we're using advanced browser features. Animation, 2D contexts, trying to do things like pointer lock. But these are all examples of things that are extremely different between each web view.
All of this has doubled (quadrupled - with dev and prod builds behaving so differently! - but that's another story) the amount of physical testing we have to do. It takes so much time to manually test and ship. When we were building for the web, this wasn't an issue even if people used different browsers. The webviews have incredibly different behavior than web browsers.
Their rationale for using OS-provided system webviews instead of a bundled runtime baked into the installer at build time is that it would save space. But in reality all it has done is created developer frustration. And wasted so much freaking time. It's the single biggest time sink we have to deal with right now.
We were sold on Tauri because of Rust, but the system browser runtime is just such a bad decision. A self-imposed shotgun wound to the chest.
The Tauri folks have heard these complaints, and unfortunately their approach to solving it is to put Servo support on the roadmap. That's 1000% not the right fix. Servo is not even a production-ready platform. We just want Chrome.
Please just let us bundle a modern chrome with our apps. It's not saving anyone any headache with smaller programs and installer sizes. Games are already huge and people tolerate them. Lots of software is large. It's accepted, it's okay, it's normal. We have a lot of space, but we don't have a lot of time. That's the real trade off.
I want to use Rust. I want to use Chrome.
I hope the Tauri devs are reading this. It's not just from me. This is the general community consensus.
Built-in webviews are not the selling point for Tauri. Rust is.
Why even bother with a browser runtime? It sounds like you have intricate UI needs, so you need a proper UI library. Several options exist.
There are some intangible matters of practicality. The team is more familiar with React.
I tried to use Bevy (since we also use 3D) and that wasn't ready for prime time.
I thought about Iced and Imgui and several other Rust frameworks, but given our experience with Bevy we shied away from it.
We figured we'd be able to move faster and rely on a lot of existing tooling. That's been true for the most part.
> Please just let us bundle a modern chrome with our apps.
please, no.
I wish software companies had to pay the hardware they require for their users, then we would have devs using Rust instead of JS and optimizing using ASM just to save parts of cents per instance. And we wouldn't see companies like MS kill well designed and performed native apps for a electron app

So use Electron and FFI, it's not that hard
Haven't touched Tauri because of the cross platform issues. The major appeal with Electron to me is the exact control over the browser. I'm curious about Rust integration though. I'm guessing they're doing something that provides better DX over something like https://github.com/napi-rs/napi-rs?
> Haven't touched Tauri because of the cross platform issues.
You were wise. That's the biggest issue plaguing the project right now.
> curious about Rust integration though
Tauri is written in 100% native Rust, so you write Rust for the entire application backend. It's like a framework. You write eventing and handlers and whatever other logic you want in Rust and cross-talk to your JavaScript/TypeScript frontend.
It feels great working in Rust, but the webviews kill it. They're inferior browsers and super unlike one another.
If Tauri swapped OS webviews for Chromium, they'd have a proper Electron competitor on their hands.
Sounds easier/more reasonable the other way around. Aren't there already specific libs / bridges for Rust / Electron / Node for performance heavy computations ?
Don’t try to speak for me please. I’m perfectly happy with my app looking mildly different and not weighing 1GB. I’m inclined to believe most people using Tauri do not have your issue.
I don’t quite understand why you have that issue in the first place. The fact they use the system webview is front, left and center on their website. It’s like you decided to use a fork because of the decorations on the back, and now complain that it’s pointy and the developers should just make it a spoon instead.
Because Tauri people advertise it as a complete solution to everything Electron does. But then they act surprised when people have platform difference issues that they don't have with Electron. Tauri is being actively misrepresented and people have good reason to feel duped.
> I don’t quite understand why you have that issue in the first place.
My read on it is that they didn’t understand the implications of using system webviews.
And possibly they expected Tauri would insulate them from cross-system differences without a lot of exploration.
This. We wouldn't have signed up for this if we'd have known.
Tauri needs a big fat warning label.
Is it hard to ship a Rust library with Electron? At least then it's not all C++
