Discord is replacing its Electron desktop app with a Rust rebuild, and the Discord Rust app already looks far lighter on memory. An early Windows 11 build showed about 290MB of RAM, while the current app can climb past 4GB.
There’s no release date yet, so you can’t download it today. Here’s what is confirmed, what isn’t, and what you can do about Discord’s memory use in the meantime.
Quick facts:
- Discord’s co-founder and CTO, Stanislav Vishnevskiy, confirmed the rebuild.
- The new client uses Rust and the GPUI toolkit, not Tauri.
- An early Windows 11 screenshot showed 290.2MB of RAM.
- No release date, rollout plan, or final name has been announced.
A skimmable list, but the numbers need context. Keep reading for why that 290MB figure isn’t the whole story.
What Discord actually confirmed about the Discord Rust app
According to Windows Latest, Vishnevskiy said “Electron goes away, and so does React Native.” The desktop app moves to Rust, and mobile keeps native interfaces while sharing code with desktop.
He also stressed the approach is “not Tauri, it’s GPUI.” Tauri usually leans on the system’s built-in web view. GPUI draws the interface directly, which is where a big chunk of the memory savings would come from.
Discord isn’t new to Rust. It has used the language since 2018 for backend and voice systems, and parts of today’s client already rely on it.
Why Electron apps eat so much RAM
Electron bundles a full copy of a Chromium browser with every app. That makes development fast, but each window carries the memory overhead of a mini browser.
Discord feels it more than most. It keeps chat history, images, GIFs, voice channels, and video streams alive, often for days.
The company has acknowledged the problem before. A Discord employee said in a December 2025 Reddit post that normal use stays under 1GB, and that a test restart kicks in above 4GB.
How the 290MB number compares
Here’s the side-by-side, based on what’s been reported so far.
| Today’s Discord (Electron) | Early Rust build | |
|---|---|---|
| Framework | Electron, which runs a Chromium-based web engine | Rust with the GPUI interface toolkit |
| RAM seen | Roughly 1-2GB idle by one reviewer’s experience; spikes past 4GB acknowledged | 290.2MB in one early Windows 11 screenshot |
| Release date | Available now | Not announced |
| Platforms confirmed | Windows, macOS, Linux, mobile | Windows 11 shown; others not confirmed |
Treat the 290MB figure carefully. The report doesn’t say whether the app was idle, how many servers were open, or how long it had been running. A fresh app with little loaded will always look lean.
It’s still a strong sign. Even if real-world use lands higher, dropping from gigabytes to a few hundred megabytes would matter a lot on older laptops.
What to do about Discord’s memory use right now
Until the new client ships, a few habits can keep the current app in check. None of these are official fixes, but they’re easy to try.
- Restart Discord every day or two. Memory tends to creep up the longer it runs.
- Turn off hardware acceleration under Settings, then Advanced, if you see stutter or high usage.
- Leave busy servers and mute channels you never read.
- Use Discord in your browser tab if you only chat occasionally.
Memory is also getting pricier. If you’re weighing an upgrade, our laptop RAM shortage buying guide explains what to expect. Also worth a look: how Discord messages could show up in Google Search starting in December.
Frequently Asked Questions
When will the Discord Rust app be released?
Discord hasn’t said. Only an early Windows 11 build has been shown, and no beta or rollout date has been announced.
Is Discord leaving Electron completely?
That’s what its CTO says. He stated Electron goes away, and so does React Native, with the desktop app moving to Rust and GPUI.
Will the new Discord work on Mac and Linux?
Unknown. The early reports only discuss Windows 11, and Discord hasn’t confirmed other desktop platforms or timing.
Is the Rust version really 70% lighter?
Not proven. The 290MB reading is one early screenshot with unstated conditions, so real-world savings could differ.
Worth the wait, but don’t hold your breath
A Rust rebuild is the right fix for a chat app that regularly hogs gigabytes. If Discord gets even close to 290MB in everyday use, low-RAM PCs will finally breathe. Until Discord shows a beta, treat the numbers as a promising preview and keep restarting the current app now and then.
