Discord is killing its Electron app that can eat 4GB of RAM on Windows 11, and the Rust rebuild uses just 290MB
AI-summarised brief · reviewed before publication
Discord’s co‑founder and CTO Stanislav Vishnevskiy announced that the company is rewriting its Windows 11 desktop client in Rust, replacing the long‑standing Electron framework. The new build, dubbed “Discord Phoenix,” uses GPUI for its interface and reportedly consumes only 290 MB of RAM, a stark contrast to the current Electron version that can exceed 4 GB under heavy use. Discord has previously acknowledged the memory bloat, rolling out a test that restarts the client when usage tops 4 GB and reporting a modest 5 % reduction in high‑percentile memory consumption. The shift to Rust follows Discord’s broader adoption of the language since 2018 for voice infrastructure and other components, and it eliminates the need for bundled Chromium and React Native code.
💡 Why It Matters
- · By slashing memory usage, Discord will become far more viable on low‑end PCs and could set a precedent for other high‑profile apps to abandon Electron in favor of native‑performance frameworks.
