Discord's Rust rebuild loads your friends list before the old Electron app even finishes booting

Is that a whole UI re-write in a native/non-web framework? Because in case that's not, this is still running in a browser, i.e. it stands at 80% or so of the bloat factor of electron, and what makes it faster is possibly (mainly?) that they haven't gotten yet to adding as much stuff as seen on the regular client.

Discord is a server-side protocol (the client isn't doing much besides displaying the server-prescribed state), there's very little logic/computation going on on there that should explain a world of difference.

Electron is pretty awesome in that it allows a small team to build a decent GUI app using their existing web skillset but it also feels like it's time for something better at this point.

With the ram prices as crazy as they are. It's pretty frustrating to have to run multiple GB eating applications just to do some basic tasks (90% is read and write messages, in the case of Discord). I understand that other people might use the more advanced features (voice chat, etc) but these could be loaded on-demand.

It's a bit crazy to me that I can comfortable run an entire Linux stack (+ Podman, monitoring, alerting and multiple services) in 512 MB ram (with 40% free, just checked!). However my Windows PC needs 5.5GB just to show the desktop! Realistically it needs somewhere between 8GB and 16GB for some basic web browsing and even then it can feel slow if you have a few apps like Discord running in the background.

I don't understand this idiocracy - it's super easy (I did myself alone many times) to have a single codebase in Qt for all OSes, even BSDs.

I think people become super lazy... "Ah, it's will ocupie a few hundreds of RAM, no problem, let's ship it."

They are companies with billions or even trillions shipping shit with Electron.

We have gotten so used to slow app startup these days I believe. I have recently started using Task Slinger [1] and every single time I boot it, I get a feeling that it was already running and it's window just showed up. I wish all modern software were like this.

I've rarely liked any Electron apps, both for the performance and because it seems to encourage a feeling of bloatedness, for want of a better word. Tried VS Code, but dropped it when they started putting too much AI in it and too much complexity. Sublime is so much better.

I don't know...there seems to be something unpleasant about all Electron apps.

Discord isn't really the model to follow here, IMO. They killed their native Android app and moved to React Native, and now they're dropping React Native (while mobile somehow keeps "native UI", according to their CTO's tweet). If they wanted to maximize code reuse and accelerate feature development, they should have instead considered Kotlin Multiplatform, then they could've skipped the React Native detour while actually building apps that are native to the platform. (Rust and its cacophony of UI frameworks are not really platform-native anywhere, as far as I'm aware. Maybe Pop OS, but I don't know anyone targeting that specifically.)

This bit is obviously subjective, but Rust as a language is simply not ergonomic enough for a lot of the use cases people are trying to apply it to, especially UI development. Most of the Rust UI libraries I've seen to date either use a more imperative style, or attempt to replicate more declarative approaches like Compose UI or SwiftUI, but without the nice language aesthetics that make it simple to read and write. And if the counter-argument there is for LLMs to be reading and writing this stuff, that's a whole other can of worms: (1) The subsidized inference era is quickly coming to an end and (2) if you're using LLMs anyway, why not maintain apps that are as native to each platform as possible?

Electron has always been about shipping cross-platform apps quickly, at the cost of higher memory usage and potentially worse performance. With or without LLMs, its core value proposition remains the same. LLMs simply amplify the framework’s existing strengths.

Raycast, originally a native macOS launcher, recently released v2 using a hybrid architecture. It’s not Electron, but it follows a similar approach to Spotify’s desktop app, using web technologies inside a native shell.

The memory usage is still pretty significant. It’s using around 350–450 MB at idle and can sometimes reach 1–2 GB depending on the workload. The upside is that they can now share most of their code across macOS and Windows and evolve beyond being just an app launcher.

It’s always been about trade-offs, and LLMs don’t fundamentally change that.
