Project Phoenix

Discord has introduced Project Phoenix, a new version of its client rebuilt in Rust. In a side-by-side demonstration, it opens in under a second, reportedly without a loading screen, and uses only a fraction of the RAM required by the current client. Discord plans to bring it to desktop and mobile.

Background

The current desktop client uses Electron, which the presenter describes as useful for some purposes but not as fast as native apps. Discord says it has been rebuilding parts of its infrastructure in Rust since 2018. In 2020, the company announced plans to move parts of Discord from Go to Rust.

Rollout

Project Phoenix is still in development. Discord plans to test it with a few hundred people first, then fix issues and improve stability and the overall experience before a broader release.
