Discord Plans to Rebuild Its Entire App in Rust, Dropping Electron and React Native

Picture Discord running on your gaming PC, eating through four gigabytes of RAM while you’re mid-match. That’s the reality for some users today. Discord wants to fix it — and the plan involves a fundamental rebuild of the application from the ground up.

On 4 November 2026, Discord co-founder and chief technology officer Stanislav Vishnevskiy posted on X to announce that the company intends to move its applications fully over to Rust, a programming language built for performance and memory safety. The post, reported by The Verge the following day, set out what amounts to one of the most ambitious technical overhauls in the company’s history.

What Discord Is Actually Changing

Right now, Discord’s desktop app runs on Electron. If you’ve never heard of it, think of Electron as a way of wrapping a website inside a desktop application — it bundles a full browser engine and ships it alongside the app itself. It’s how a lot of popular software works, including Slack and Visual Studio Code. Convenient for developers. Not always kind to your computer’s memory.

On mobile, Discord uses React Native, a framework that lets developers share code across iOS and Android while still delivering interfaces that feel native to each platform.

Both of those are going away.

Vishnevskiy said: “That means Electron goes away, and so does React Native, mobile keeps native UI but shares app code with desktop via Rust.”

So mobile users won’t see their interface change sharply — the look and feel of the iOS and Android apps should remain native to those platforms. But underneath, the shared logic of the application will be written in Rust, running across both desktop and mobile from a single codebase. The rebuilt client is reportedly being developed using GPUI, a graphics and UI framework, rather than a browser-based approach.

Eight Years in the Making

This isn’t Discord suddenly discovering Rust. The company has been building with it quietly for nearly a decade.

Vishnevskiy was direct about that history: “We’ve been early adopters of Rust since 2018 and a lot of our infra, voice tech, and even some of the current client is already Rust, the holy grail was getting the whole client there.”

That phrase — the holy grail — gives a sense of how long this has been sitting on the roadmap. Rust is already woven through Discord’s infrastructure and voice technology. The new plan is to extend that to the entire client application, desktop and mobile alike.

What the Performance Claims Actually Mean

Here’s where it’s worth being careful. Early testing on a Windows 11 build reportedly showed the rebuilt client using around 290 megabytes of RAM. By comparison, secondary technology reporting has suggested the current application can reach up to four gigabytes in some circumstances — though neither figure comes from an official Discord benchmark.

That gap, if it holds in the final product, would be meaningful. Discord is used heavily alongside games and other demanding software, where every spare megabyte counts. But an early build is an early build. Performance on one machine in controlled conditions tells you only so much about how software will behave across millions of different devices.

Discord has not confirmed a release date. Vishnevskiy said the company hopes to “get it into testing with users soon” — which is encouraging, but not a schedule.

A Rewrite of This Scale Carries Risk

Rewriting a major application from scratch is a bet. It can pay off handsomely — a leaner, faster, more stable product. But it can also surface unexpected bugs, break workflows that users have relied on for years, and create compatibility headaches that take time to resolve.

And Discord is not a small application. It serves hundreds of millions of users across gaming, education, creative communities, and professional groups. A rocky rollout would be noticed immediately.

The company hasn’t said how the testing phase will be structured, whether it will be opt-in, or how quickly it might scale. Those details matter — and they haven’t been shared yet.

What This Means for Kent Residents

For Discord users across Kent — whether you’re gaming in Maidstone, studying in Canterbury, or running a community server from Folkestone — nothing changes for now. The existing desktop and mobile applications remain in place until Discord opens testing or announces a wider release. If the rebuilt client does deliver lower memory use in its final form, it could be good news for anyone running Discord on an older or less powerful machine, where the current Electron-based app can feel sluggish. Any specific arrangements for UK users, including compatibility requirements or rollout timing, remain unconfirmed.
