Zed
Open SourceLightning-fast code editor for developers and AI collaboration
AI Summary
Zed is a minimalist code editor built in Rust, designed for speed, AI assistance, and real-time collaboration. It leverages multiple CPU cores and the GPU for native performance and enables parallel execution of AI agents directly within the editor. The tool is aimed at developers looking for a fast, modern editor with integrated collaboration and AI functionality.
✓ Pros
- +Extremely fast thanks to Rust implementation with GPU and multi-core utilization
- +Integrated AI agents and collaboration features built directly into the editor
- +Available for macOS, Linux, and Windows with active open-source development
✗ Cons
- −Relatively new tool – ecosystem and extension library are still growing
- −Developers accustomed to established editors may face an adjustment period
Use Cases
- →Running AI agents in parallel for automated code editing and navigation
- →Real-time collaboration with team members including screen and project sharing
- →High-performance coding with native GPU and multi-core support
- →AI-assisted code reviews and bug fixing directly within the editor
Who is it for?
Zed is ideal for professional software developers looking for a lightning-fast editor with native AI integration and real-time collaboration.

What is Zed?
Zed is a code editor written in Rust, built with a consistent focus on execution speed. Rather than using a renderer like Electron, Zed handles rendering tasks directly via the GPU and distributes load across multiple CPU cores. The result is an editor that responds without noticeable delay even on large projects. Zed is open source and runs on macOS, Linux and Windows.
Core features
- GPU and multi-core rendering: Zed uses graphics hardware for rendering and distributes computation in parallel, which is especially noticeable when scrolling through large files and with complex syntax highlighting.
- Parallel AI agents: Multiple AI agents can be started simultaneously in the editor to work through code tasks at the same time, rather than handling them sequentially in a chat window.
- Real-time collaboration: Teams can work on the same project together, including screen and project sharing directly from within the editor.
- AI-assisted code reviews: Bug finding and reviews run integrated in the editor, with no context switch to an external tool.
Who is Zed for?
Zed is aimed at developers who run into loading times and memory usage with VS Code or similar editors and are looking for a leaner alternative. Teams that want real-time collaboration without a separate tool also benefit from the built-in sharing. Those who depend on a broad extension ecosystem will find that Zed's library of extensions is still considerably smaller than established alternatives. Anyone who needs specific plugins for frameworks or legacy toolchains should check availability before switching.
Context & alternatives
Zed competes directly with VS Code and JetBrains IDEs. VS Code offers a significantly larger extension ecosystem, but runs on Electron and consumes more resources accordingly. JetBrains products provide deeper language support and mature refactoring tools, but are paid and heavier. Zed is the youngest of the three and is catching up on the ecosystem. Developers working primarily in Rust, Go or TypeScript who do not need obscure plugins can already work productively in Zed today.
