Discord Rebuilds Desktop App in Rust to Improve Performance

Discord has officially announced a major shift in its technical architecture, confirming that it is moving away from its long-standing Electron-based desktop application. The decision comes after years of user feedback regarding the high resource consumption of the current app, which has been known to consume up to 4GB of RAM on Windows 11 systems.

The company is currently rebuilding its desktop and mobile applications using the Rust programming language. Early builds of the new Rust-based application have shown staggering improvements in efficiency, with memory usage dropping to as low as 290MB. This transition represents a significant engineering undertaking aimed at providing a smoother, faster, and more responsive experience for its millions of users.

Electron, the framework previously used by Discord, is based on web technologies and is often criticized for its heavy memory footprint because it essentially runs a dedicated instance of the Chromium browser for the application. By switching to Rust, a systems programming language known for its performance and memory safety, Discord is able to achieve native-level performance that was previously unattainable.

Industry observers have praised the move, noting that it reflects a broader trend among major software companies to prioritize performance and resource optimization as applications become increasingly complex. For the average user, the change is expected to result in faster startup times, reduced battery drain on laptops, and a more stable environment for multitasking while the app is running in the background.

Discord’s CTO has confirmed the shift, signaling that the company is committed to long-term technical debt reduction. While the transition will take time to roll out across all platforms, the early results suggest that the move to Rust will be a game-changer for the platform’s usability. Users can expect a more streamlined experience that doesn’t sacrifice the feature-rich environment they have come to rely on for communication and community building.
