Zed is a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter, written from scratch in Rust. It is designed for speed and real-time collaboration with both humans and AI — leveraging multiple CPU cores and the GPU (via its GPUI framework) to deliver a responsive editing experience.

Key Features

• GPU-accelerated UI — the custom GPUI framework renders the interface at high frame rates, for near-instant response even in large files
• Multiplayer collaboration — share your workspace with others in real time via Zed Channels and shared links
• Native agentic AI support — bring agents like Claude Agent or Codex, or connect MCP servers to extend the editor’s knowledge
• Language Server Protocol (LSP) — full language support with inlay hints, syntax-aware selections, and diagnostics
• Multibuffer editing — compose excerpts from across your project for cross-file find-and-replace
• First-class Vim bindings — modal editing with text objects and marks
• Built-in REPL and debugging — native debugging support via the Debug Adapter Protocol (DAP) across many languages
• Extensible — hundreds of extensions for language support, themes, and more

Why Use Zed?

Zed targets developers who want a native, low-latency editor that feels responsive on modern hardware. It is especially well suited to pair programming and AI-assisted workflows, and its open-source core means anyone can build from source or audit the code.
