Same Discord.
Way lighter.
Phoenix is the new Discord app, rebuilt in Rust. Same app, a fraction of the memory.
Built in Rust
Discord has used Rust since 2018 for infrastructure and voice. Phoenix brings the entire app there, ditching Electron and React Native, and draws every pixel with GPUI.
Measured on Windows 11 with two accounts open. Results vary by system.
Light on your RAM
Leave Discord open all day while you game, stream and work. Phoenix uses a fraction of the memory the current app does.
Feels instant
Same look, same features, way less waiting. Mobile keeps its native interface and shares app code with desktop through Rust.
Got questions?
How much RAM does it use?
About 290 MB on Windows 11 with two accounts logged in, versus 1 GB or more on some installs of the current app.
Is it built on Tauri?
Nope. Phoenix is built on GPUI, a Rust UI framework.
Will it look different?
No. It looks and works just like the current Discord.
Will it be faster?
That’s the goal. Boot is quicker, clicks feel instant, and it uses far less memory.
What about mobile?
Mobile keeps a native UI, drops React Native, and shares app code with desktop through Rust.
