Zed¶

What it is¶

Zed is a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter. Written in Rust, it is designed to leverage every core of your CPU and every pixel of your GPU to provide an exceptionally fast and responsive coding experience.

What problem it solves¶

It addresses the latency and resource consumption issues common in Electron-based editors (like VS Code). Furthermore, Zed integrates AI and real-time collaboration natively into the core of the editor, rather than treating them as secondary plugins, which allows for more seamless and high-performance AI interactions.

Where it fits in the stack¶

Development & Ops / Editor. It serves as a high-performance alternative to VS Code and Cursor, particularly favored by developers working in performance-critical languages like Rust, C++, or Go.

Typical use cases¶

Low-Latency Coding: Ideal for developers who are sensitive to input lag.
Native AI Pairing: Using the built-in "Assistant" panel to chat with models like Claude 3.5 Sonnet or GPT-4o.
Collaborative Coding: Real-time "multiplayer" editing where multiple developers can see and edit the same file simultaneously with low latency.
Rust Development: Excellent support for the Rust ecosystem, given the editor's heritage.

Getting started¶

Installation¶

On macOS or Linux, Zed can be installed via a simple script or by downloading the binary:

curl https://zed.dev/install.sh | sh

Configuration¶

Zed uses a JSON-based configuration file. You can open it via Cmd+, (macOS) or Ctrl+, (Linux).

Technical examples¶

Configuring Native AI (Anthropic/OpenAI)¶

Zed allows you to configure multiple AI providers natively.

// ~/.config/zed/settings.json
{
  "assistant": {
    "default_model": {
      "provider": "anthropic",
      "model": "claude-3-5-sonnet-20240620"
    },
    "version": "2"
  },
  "language_models": {
    "anthropic": {
      "api_key": "YOUR_ANTHROPIC_API_KEY"
    },
    "openai": {
      "api_key": "YOUR_OPENAI_API_KEY"
    }
  }
}

CLI Usage¶

The zed CLI (often aliased to zedit) allows you to interact with the editor from the terminal.

# Open a file or directory
zed .

# Open a specific file at a specific line
zed path/to/file.rs:42

# Use zed as your git editor
export GIT_EDITOR="zed --wait"

Key Bindings for AI¶

Zed provides several shortcuts for its AI assistant: - Cmd+Shift+>: Open/Close Assistant panel. - Cmd+Enter: Send message to AI. - Cmd+Shift+I: Inline AI transformation (refactor selected code).

Strengths¶

Performance: Extremely fast startup and zero-latency typing experience.
Native AI Integration: The Assistant feels integrated, not "bolted on".
Multiplayer: First-class support for real-time collaboration.
Resource Efficiency: Significantly lower memory footprint compared to VS Code.

Limitations¶

Ecosystem: Much smaller extension library than VS Code.
Platform Support: Windows support is still in development/beta compared to the mature macOS and Linux versions.
Feature Maturity: Lacks some of the deep "quality of life" features found in older IDEs.

When to use it¶

When you want the fastest possible editor performance.
When you frequently pair-program and need a low-latency collaborative environment.
When you want native AI features without the overhead of heavy VS Code extensions.

When not to use it¶

When you rely on specific, complex VS Code extensions that don't have Zed equivalents.
When you are working on a Windows machine (check current status of Windows support).
When you need deep, specialized IDE features for enterprise Java or .NET development.
