I had trouble reading more than the opening volley of the article due to popups. Am a Discord user, and rust application programmer: What GUI framework are they using? EGUI? GPUI? Something custom?
GPUI from comments? I meant to try GPUI, but backed off after an announcement pending its maintenance would be in question (?) a few months ago, and Zed broadly ending up being a false messiah, for my uses. (Not on the tier of JetBrains IDEs, a bug with a long thread they closed which (still I believe?) causes it to open cached versions of files, then clobber edits made since the cache, e.g. by other programs. I.e. the sort of bug which renders software too dangerous to use. I will not switch to a GUI framework from a group that ignores bugs of that severity reported by many people)
They’re showing how easy it is to vibe code a port of the app. A motivated developer outside Discord could do the same and release OpenDiscord or whatever if they cared enough to want to mod the app that way.
This is the way, LLMs are an enabler and force multiplier to help you build whatever interface you want on whatever protocol you have to reverse engineer.
Provide it the official client and point it at public api endpoints (or an LLM operated mitm proxy), set it to work to reimplement.
I'm very interested in (and a total novice in) cross platform GUI application development. Hadn't heard of GPUI, though I had heard of Tauri. I looked at the GPUI front page and saw this mess of almost-CSS method chaining... Surely there's a better way? This seems horrible to me.
That's a result of the borrow checker meeting dev ergonomics. Method chaining/functional style ks extremely common. GPUI is also fairly low level, it lets you do a ton of things!
This has to be hyperbole. I built (with Claude) a P2P LAN voice-only chat app in Rust recently, using native frameworks for each platform (Swift, GTK, Win32), and it weighs in at about 5-6 MB depending on the platform. I have spent an enormous amount of time looking for places to squeeze it further. It has ephemeral channels and password protection, but that’s about it: no text chat, no video, no friends, blocklists, no concept of servers, etc. I can’t imagine everything else Discord has squeezes into another 5 MB.
It's probably left over old instances and updates that werent deleted properly. These apps tend to download the update as an entire bundle, rather than any sort of binary diff and patch.
Therefore, if you have an old install and have gone thru several (many) cycles of updates, the installation directory could be riddled with old versions and update files that make up the bulk of that 10 gig.
It can and it does, because it drops a ton of code for scenarios that do not exist. (Not these numbers, of course, but if you check the comments of that account.. well. Yeah. Some kid)
Electron rose to fame because one could just do everything with it and it was good enough.
Being able to do everything also means that the thing can do everything everywhere all at once, which is many lines of code.
___
The magic of electron was that it was "cheap", however, with code being all AI-generated, that's even cheaper. So now everything will be some slop rust until the point when people realize that there is a cost to be paid after all.
For electron, that has been RAM and performance. For the vibeslop.. well. We shall see.
Unironically, with LLMs, everyone should be looking to cut their system resource consumption (memory, disk, network, GPU, I/O traffic in general) and rewrite everything natively. Have a platform-independent business logic layer, and a platform-dependent UI/UX layer. Done. It's not even that hard, and has been done several times over; we quite literally have MVC/MVVM/etc that were invented two decades ago.
Operating systems developers should be looking to profile everything. Benchmarking and profiling used to be horribly time-consuming; nowadays, with agents, this is almost trivial. Then valuable engineer time can be spent looking at actually solving and optimising the workloads, from the kernel, to drivers, to user-mode libraries, to vendored applications.
About a decade ago programming was expensive, and we decided writing everything in JavaScript was OK, and wasted everyone's memory instead of using programmer time to write fast and efficient native applications. This is no longer the case.
> Unironically, with LLMs, everyone should be looking to cut their system resource consumption (memory, disk, network, GPU, I/O traffic in general) and rewrite everything natively.
Depends.
There is a lot of value in man-made software where the man knows exactly what happened where when why.
If you just revibe in rust, you get something that works at this point in time, but this deep architectural knowledge is completely lost and you're at the mercy of Dario not locking down your account for wrongthink.
That can still be fine for smaller tools where the cost of recreating them from scratch is alright, but revibing your core business thingy is likely a horrible idea, which I encourage people to do, as I'd love to have the business opportunity to take over their frustrated customerbase ca 5 years from now.
I don't think we should just 're-vibe' it as you put it. Naturally the rewrite should be progressive and thoughtful, backed by test-driven development at all levels, and regression tests every step of the way. To reiterate: writing code used to be a lot more expensive, which justified foisting React, Electron, JS on everyone. No longer the case.
I've mentioned in another comment, but my biggest pet peeve is that AI agent applications (Claude, GPT, etc) are themselves just Electron wrappers over their web pages. What a waste.
Push-to-talk does not work well on in the browser at least on Wayland/Linux. The shortcut only gets sent to the active window, which for the type of contexts where push-to-talk is useful (e.g. gaming) is a dealbreaker. I've read stuff indicating that xdotool can manually handle things reasonably enough on X11, but I was never able to get it working reliably for any of the various Wayland replacements for xdotool, so when I've done voice calls, I've had to grudgingly use the desktop client.
I noticed this news and because one of my codex banked reset is expiring soon
I launch codex with astra+ultra on my tauri project because webview sometimes cause blank screen on user device to let it to rewrite the tauri projec to GPUI
It did those stuffs for me
- get rid of the CGO and MINGW toolchain for cross building windows on Linux
- wrote a compatbility layer to communicate the original app backend written using rust
- Achieve not ideal but acceptable UI/UX as the tauri project
- The new build using 24MB memory which is quite good and I do not even bother to check the tauri version
It amazing time to rewrite, though I still can't remember joy of old days that manual coding, but my lower back ask me to just embrace the Agentic coding...
I just pray that Vencord will continue to work in some form, if only so I can use whatever font I want. I'm not a fan of many other changes they've made and I've thus had to reverse, but I'm willing to trade away the flexibility of CSS for an app that uses 5 times less RAM. Even better if it doesn't go away at all, but we'll see.
It's great they're working on improving performance, but as they move towards an IPO I'd be looking hard at getting off their platform altogether. They're already shoehorning ads and all kinds of nonsense into their app- it's only going to get worse after the IPO.
Network effects keep me on it. I'm waiting for the day it collapses so I can spin up a Teamspeak (or whatever) server again, but it's just too darn convenient for everybody else, so I'm stuck with it unless I want to become even more of a hermit.
It's crazy how much RAM electron needs, at my old startup the main product was an electron app, i initially used to run into this issue where AI wouldn't clean up the dev builds it spunned up for e2e testing and each could be over 500MB, it just get's to a point that the cross platform advantage is no longer worth it, i think it was one of the main reasons cursor had to move off electron to rust based builds.
Electron being bad is a bit of a junior- to mid-level engineer tell in my eyes, the sort of thing you'd say if you've just learned that some apps use more RAM than others, maybe built a small Rust TUI and are now wondering why not everything is using Rust. Something you'd believe just before you learn what engineering trade-offs are.
So, yeah, enjoy rebuilding complete browsers, I guess? I'm sure they'll run more efficiently than the rendering engines that have been refined and tweaked over the course of now multiple decades.
Well, unless you leave out the annoying stuff, like a11y, IME, RTL, but who needs those things anyway, am I right.
Then you find out that iterating on a fully Rust-based app is sloooow, so you add a scripting layer, maybe integrate a little Lua VM or something that lets you execute JavaScript?
Congratulations. You've built a browser, just with fewer features, more bugs, and probably higher RAM usage. Good job.
Electron is bad, just because Rust is not a good language for building UIs doesn't make electron not bad. People that pick electron (and Rust / gpui) just completely ignore the entire host of other options that are available (I suspect because they want to avoid thinking).
> is a bit of a junior- to mid-level engineer tell in my eyes
There is absolutely no reason for Discord—a chat application—to run everything a browser does. Why do I need to play videos in the chat application? Why do individual avatars and even tags have to run custom shaders? It's called scope creep.
> a11y, IME, RTL
All of this can be done at the platform level. Win32 did this three decades ago. Comes with entire language packs.
> so you add a scripting layer, maybe integrate a little Lua VM or something that lets you execute JavaScript
See above: scope creep; features for features' sake.
> Then you find out that iterating on a fully Rust-based app is sloooow
Maybe not anymore. I don't work on any Chrome-sized Rust codebases so I don't know, but iterating on anything is so much faster that it might work out fine.
There was already an electron-free native client for discord some years back, but they interfered with it. At this point, there's nothing at all impressive about this. It's not hard to ask AI to "RIIR" as has been shown many times. However, I am glad that building stuff on electron might finally be seen as lazy and wasteful.
Sure, a Rust implementation will perform better and use less RAM, but it's quite obvious that the transition to Rust will be done almost entirely by AI.
Don't get me wrong, the AI coded Rust version of Discord will most likely work just fine. The thing I'm wondering about is if it's a good idea to rewrite your whole codebase (which I assume is handwritten since Discord predates AI coding) with AI because now there is nobody that knows how it really works - I'm wondering what's the value of having a human-written codebase + the people who wrote it. Just feels like one shouldn't throw that into the trash like it's nothing?
I'm with you and I think a variety of companies are going to learn this in a highly expensive way over the next few years. Once your shared mental model of how the codebase works is gone it seems practically impossible to get it back. Like what would you even do if you change your mind in 3 years - sit everyone down to meticulously comb through all the AI code until they start to get how it works? Getting back to a similar level of understanding seems like it would take ages and effectively locks you into the new solution in a way that cannot be feasibly reversed.
How is this different from when you join a company and learn your corner of the codebase? In a sufficiently large enough codebase no one had the whole mental model in their head even before AI. What you did was find and ask that one person who knew enough about some part of the project to answer your questions. Now you can ask a model.
Well not really? You are going from a webpage (Electron) to a native application via Rust. Say you port a React website to a Rust native application, is anything about that code actually similar?
Here's the critical assumption: Somebody has to know how it works, in order for it to be usable.
That's not actually true. Nobody understands everything about how an airplane works, not even the lead engineers. Nobody understands everything about how a car works, or how medical billing works, or how taxes work, or how traffic flow works, or how a CPU works, or how almost anything works. You just need to understand the broad picture and be able to find the details when necessary.
Your post is absolute nonsense. Plenty of people know exactly how everything on a plane or car works, or a CPU. I've worked with tons of people who do.
The fear of deskilling is very valid and is already messing things up.
Asking in good faith: In the agentic age why use abstractions like Electron at all? Shouldn't we write apps in lower-level system languages like Rust like Discord has done?
I am not a developer, but using this type of frameworks and toolkits means that a lot of useful (and sometimes "boring") things are already thought through and taken care of. This is probably most important for smaller projects and teams, but some of it probably applies to Discord scale operations as well :)
While you _should_ put some effort into tuning and fixing these things for your specific project, you will "mostly" get things like cross-platform support for all major desktop operating systems, some support for accessibility-tools like screen readers and voice over, devtools and debuggers, application installers, (push) notifications, caching, some aspects of security and cryptography, log handling, and file handling for free, or at least get a reasonable push in the right direction, with Electron.
The alternative is either getting each of these things from a different third party source, or making them all in-house.
With a popular abstraction layer like Electron + a web stack, you will to some extent encounter the same problems, mysterious log messages, design considerations and other issues as everyone else. This means that you can find documentation, stack overflow questions, new hires, consultants, blogs, LLMs, etc. that have the skills and knowledge you need, instead of researching and solving everything in-house.
We've barely begun seeing the impact of AI on software (IMHO). Things like vibecoding the Adobe suite are going to destroy Adobe. That's going to happen to other companies too. It'll take awhile but it will happen.
I've always disliked Electron apps in principle. The idea was you could write once, run anywhere, which is something we've heard before so many times but it never really works out that way. Back in the early days of Java we heard this mantra with applets and Java desktop apps and the reality was "write once, test everywhere".
The cost is simply too high. Nobody wants an entire browser engine packaged to run a desktop app. Security-wise, this is a nightmare. It's such a huge attack surface (eg [1]). And resource-wise it's also a nightmare. Honestly, Electron apps can't die fast enough for my liking.
What I think we'll see is a return to desktop apps because the cost of porting them to new platforms is dropping like a rock.
There are modding issues with Discord's migration but I believe modding itself is going to be an issue in a world where it's going to be increasingly easy to find and use exploits.
I also wonder if Discord is the best we can do here. I've always hated Discord from a UI/UX perspective. Nothing about it is intuitive (IMHO). There are like 3 different settings buttons. You join a Discord and you get yet another custom flow of having to go to this channel and select roles and do something before you can do something else blah blah blah. Everything feels shoe horned. And Discord channels are a worse repository for information than the old forums were.
You have not been paying attention the last two years, as they decided to go subscription instead of loaded with ads like anything nowadays owned by Future, like Toms Hardware, Anything Central.
If all products ditch Electron, it satisfies the NSA requirements of having AI-generated backdoors on your computer, while allowing you to reduce your RAM consumption and letting this precious silicon for Sam Altman (He's quoted saying RAM is better spent in data centers than in personal computers - and in an era where everything is Cloud, one might wonder why the base Macbook Pro has 32GB).
GPUI from comments? I meant to try GPUI, but backed off after an announcement pending its maintenance would be in question (?) a few months ago, and Zed broadly ending up being a false messiah, for my uses. (Not on the tier of JetBrains IDEs, a bug with a long thread they closed which (still I believe?) causes it to open cached versions of files, then clobber edits made since the cache, e.g. by other programs.

If it were simply the Chrome install that would imply Electron is 9GB+ by itself, which it most certainly is not.
Therefore, if you have an old install and have gone thru several (many) cycles of updates, the installation directory could be riddled with old versions and update files that make up the bulk of that 10 gig.

Inference cannot be controlled. The models are already out there. It's too late.
That needs claude-like capabilities.
It also should not be done at all. But that approach needs it.
Using open weights models like GLM-5.3 can also speed up rewriting, but then you're rewriting and not revibing, which is a lot slower.

Also naming your company "__slop" is a bold move!
Activities will apparently still use Tauri. Is that going to be a compatibility nightmare due to WebKit? (At least until CEF comes out)
