Discord Rust App: Why Discord Is Ditching Electron for Rust

If you've ever opened Task Manager and wondered why a chat app is using more memory than your game, help is on the way. Discord is building a new Discord Rust app for desktop and mobile, and it drops the Electron framework its desktop app has always used.

Co-founder and CTO Stanislav Vishnevskiy confirmed the rebuild on X on 4 November 2026. Over the next two days, he shared a Task Manager screenshot, a desktop boot-time video and an Android demo.

There's no release date yet. Here's what's confirmed, what the early numbers really mean, and what you can do while you wait.

At a glance - 3 November: Vishnevskiy hints the team is "busy with a much bigger update" - 4 November: he confirms the whole client is moving to Rust, and shares a Task Manager screenshot - 5 November: he posts a desktop boot-time video - 6 November: he shows the new Android app - Built with: Rust and GPUI (not Tauri) - Replaces: Electron on desktop and React Native on mobile - Release date: none yet; testing with users "soon"

🔍 What Discord Confirmed About the Discord Rust App

Discord hasn't published a blog post yet. Everything comes from Vishnevskiy's posts and replies on X.

He wrote that Discord has been using Rust since 2018, and that "a lot of our infra, voice tech, and even some of the current client is already Rust." He added: "the holy grail was getting the whole client there." Back in 2020, Discord's engineers explained why they moved a key server service from Go to Rust: it removed regular latency spikes.

Here's what he confirmed, as reported by Inven Global, Windows Latest and Hardware Busters:

• Electron goes away, and so does React Native on mobile.
• Mobile keeps a native interface but shares app code with desktop through Rust.
• It's built on GPUI, not Tauri. Vishnevskiy said: "it's not Tauri, it's GPUI."
• It looks the same. He said the app "looks and works identically to the current one."
• A system webview is still used for a few things, like YouTube and Activities.
• Testing comes first. He said the team hopes to get it "into testing with users soon™."

GPUI is a GPU-accelerated interface framework for Rust, made by the team behind the Zed code editor. The new app draws its own interface instead of running a web page.

🧠 What Is Electron, and Why Does It Use So Much RAM?

Electron is a framework for building desktop apps with web technology. According to its own documentation, it works by "embedding Chromium and Node.js" inside each app.

In plain terms, the current Discord desktop app is a website running inside its own copy of a browser. Discord's help centre says so directly: "We're based on chromium which has a multi-process model." That's why you see several Discord processes in Task Manager.

Each process needs its own memory, and every Electron app ships its own browser engine instead of sharing one.

Discord has admitted the memory problem. In December 2025, a Discord employee said on Reddit that the team was testing an automatic restart when memory went over 4GB, adding that "normal usage is <1GB," according to Windows Latest.

📊 What the 290 MB Screenshot Really Shows

Vishnevskiy's first post included this screenshot of Windows Task Manager.

The process is called Discord Phoenix, and it shows 290.2 MB of memory. Vishnevskiy later said the client was running two accounts at once, according to Inven Global.

The same screenshot also lists other apps on that PC. These are numbers from one moment on one PC:

What about the current app? Discord hasn't published a before and after comparison. Reporters have shared their own figures instead:

• Windows Latest says Discord uses 1 to 2GB on its reporter's PC, even when idle.
• 9to5Google's writer says his current PC client uses about 1,200MB.

Those are single machines with unknown settings. Hardware Busters notes that the real test will be a long session with voice and screen sharing.

📱 What Changes on Mobile

On 6 November, Vishnevskiy posted: "We didn't forget about mobile, especially Android." He said the new app is "inspired by React Native" and "drives the OS-native view layer through the same Rust codebase as the new desktop app."

9to5Google described the video, which shows two older, lower-end phones. In its account, the current app takes about 3 seconds to launch and another 2 seconds to load. The new one "launches in under 1 second." 9to5Google didn't test this itself.

Vishnevskiy also says it "uses a lot less RAM," but hasn't shared a figure.

🎮 What It Means for Everyday Users

If it works as promised, you could notice:

1. Lower memory use, which matters most on PCs with 8GB or 16GB of RAM while gaming.
2. Faster startup. Vishnevskiy's 5 November post says "Clicking around feels instant" and asks viewers to "Check out the boot time."
3. The same Discord. No new layout to learn, based on his "identically" comment.

That speed claim comes from Discord's own video. Independent tests will have to wait.

❓ What's Still Unknown

Discord hasn't confirmed any of these yet:

• Release date. There isn't one. Only "soon™" for testing.
• Mac and Linux. Everything shown so far is Windows and Android.
• Client mods like BetterDiscord. Discord hasn't commented. Hardware Busters expects mods that hook into Electron to break, which is the outlet's opinion. Discord's help centre already lists client mods as unsupported for bug reports.
• How testing will work. Discord hasn't said whether it'll go through its Canary and PTB testing apps, or invites.

🛠️ What to Do Until the Discord Rust App Arrives

You don't need to do anything yet, but a few steps help:

• Stay on the official app. There's no public download, so any site offering "Discord Phoenix" isn't Discord. Our guide to spotting fake giveaways and staying safe on Discord covers the same kind of bait.
• Try Game Mode if you have it. Discord's experimental Game Mode lowers CPU and GPU load during games, though it doesn't target RAM.
• Restart Discord if it has been open for days and feels slow.

We're also putting together a guide to cutting Discord's RAM use, so look out for that soon.

Frequently Asked Questions

What is the Discord Rust app?

It's a rebuilt version of Discord's desktop and mobile apps, written in Rust. It replaces Electron on desktop and React Native on mobile, and uses the GPUI framework.

When is the Discord Rust app coming out?

Discord hasn't given a date. Vishnevskiy said it should go "into testing with users soon™."

Does the Discord Rust app really use 290 MB of RAM?

An early Windows build showed 290.2 MB in a screenshot shared by Discord's CTO, with two accounts logged in. It's one screenshot, not an official benchmark.

Will BetterDiscord work with the new app?

Unknown. Discord hasn't commented, and the new app won't run on Electron, which many mods rely on.

🎮 The Bottom Line

The Discord Rust app is one of the biggest changes to Discord's apps in years. It keeps the same look and features, but drops its bundled browser engine. The early 290 MB screenshot is promising, though it's one machine and one moment.

The real test is a long gaming session with voice and screen sharing. Until Discord ships a test build, treat every number as a preview.

Would a lighter Discord change how you use it while gaming?
