How Zed Overcame Linux Challenges to Deliver a High‑Performance Code Editor

Overview

Zed is a collaborative code editor originally created by the author of Atom. Its core is written in Rust, includes rust-analyzer by default, and targets high‑performance editing.

Open‑source timeline

The project was open‑sourced in January 2024, initially supporting only macOS. After roughly three months the team added Linux support, allowing users to compile and run Zed on Linux distributions.

Technical challenges for Linux

The Linux port required work on the proprietary GPUI framework and had to cope with the fragmented nature of the Linux ecosystem. Unlike a single unified GUI layer, Linux distributions (e.g., Ubuntu, Debian, CentOS, Arch, Gentoo) provide different system components, so the editor must handle multiple runtime environments.

Key challenges include:

Ensuring proper window resizing and moving under Wayland.

Implementing system dialog boxes within GPUI.

Resolving 86 pending tasks of varying difficulty that block an alpha release.

Alpha release goals

To ship an alpha for Linux the team aims to:

Close the 86 outstanding issues.

Make window management (resize/move) work reliably on Wayland.

Provide native system dialogs through GPUI.

Post‑alpha roadmap

After the alpha, development will focus on adding:

Audio call integration.

Drag‑and‑drop support.

Secure credential storage.

Continued performance tuning and stability improvements.

Building Zed on Linux

To try Zed on Linux you need:

Rust toolchain (stable channel).

System dependencies required by GPUI (e.g., libgtk-3-dev, libwayland-dev, pkg-config, and other X11/Wayland libraries).

Sufficient CPU and memory; compilation can be lengthy depending on hardware.

Typical build steps:

git clone https://github.com/zedapp/zed.git
cd zed
cargo build --release

The resulting binary is placed in target/release/zed and can be executed directly.

Performance claim

Zed’s slogan, “Code at the speed of thought,” reflects benchmark comparisons that show lower input latency than editors such as VS Code and Sublime Text.
