Zed: High-Performance GPU-Accelerated Code Editor

What is Zed?

Zed is a next-generation code editor built by the original creators of Atom and Tree-sitter. Engineered from scratch in Rust, it rejects Electron in favor of direct GPU rendering, ensuring that every frame renders at the monitor’s native refresh rate (up to 120 FPS).

Zed couples raw rendering performance with native Tree-sitter parsing for accurate syntax trees, integrated Language Server Protocol (LSP) support, and built-in real-time collaborative editing.

Key Architectural Strengths

• GPU-Accelerated Rendering: The entire interface is drawn directly using hardware graphics shaders (Metal on macOS, Vulkan/DirectX on Linux and Windows), eliminating DOM layout reflows.
• Tree-sitter AST Core: Syntax highlighting, code navigation, and structural edits operate on dynamic Abstract Syntax Trees for superior precision.
• Multiplayer Collaboration: Built-in shared workspace channels allow real-time multi-cursor pairing, shared terminals, and screen streaming.
• WASM Extension Architecture: Extensions run in sandboxed WebAssembly runtimes, ensuring that third-party plugins cannot freeze the editor thread.
