Zed delivers unmatched speed and performance
Zed provides extreme performance through a custom GPUI framework, starting in just 0.12 seconds and using only 142 MB of RAM. This Rust-native editor offers native AI integration and low-latency multiplayer editing via CRDT technology to compete with VS Code and Neovim.
The Zed team built Zed in Rust to ensure extreme speed. It uses a custom GPUI graphics framework for GPU-accelerated rendering. This framework delivers 120fps rendering and keeps typing latency below 10 milliseconds. One test shows Zed starts in 0.12 seconds, which is ten times faster than the 1.2 second startup time of VS Code. Large files over 100MB load eight times faster in Zed. While VS Code consumes about 730 MB of RAM, Zed requires only 142 MB. Developers who prioritize low latency and efficient memory usage frequently choose Zed because the native Rust implementation avoids the high resource consumption typically seen in Electron-based editors like Visual Studio Code. The creators of Atom and Tree-sitter designed the editor for performance.
| Metric | Zed | VS Code | Neovim |
|---|---|---|---|
| Language | Rust | TypeScript | Lua |
| Startup Time | ~0.12s | ~1.2s | <0.1s |
| Memory Usage | ~142 MB | ~730 MB | Minimal |
| Extensions | 1,000+ | 50,000+ | Thousands |
| AI Support | Native | Extension | Extension |
AI integration and real-time collaboration
Zed includes AI as a native feature. It supports models like Claude, GPT-4o, and Gemini. The editor does not upload code to third-party servers by default. The Personal plan is free and allows users to use their own API keys. The Pro plan costs $10 per month. This plan includes unlimited edit predictions and $5 in monthly tokens for hosted models. Zed uses CRDT technology for real-time, multiplayer editing. This technology allows multiple users to edit the same file with low latency. VS Code requires the Live Share extension to provide similar functionality. GitHub Copilot works in VS Code as an extension. The Copilot Free plan provides 2,000 completions per month. The Pro plan costs $10 per month and includes unlimited completions. GitHub Copilot scored 8/10 in recent tests, while Zed scored 6.8/10. Copilot scored 1.2 higher overall in separate runs of standard tasks. Cursor is a VS Code fork that focuses on AI. Its Pro tier costs $20 per month. Cursor uses codebase indexing to understand entire projects. It also uses a Composer mode for multi-file task execution. Devin Desktop provides unlimited Tab completions and inline edits on its free plan. The Pro plan costs $20 per month. Google Antigravity’s Individual plan includes unlimited Tab completions.
The extension gap and remote development
VS Code maintains a 74% market share and contains over 50,000 extensions. Zed contains over 1,000 plugins. You likely encounter lag when your editor reaches a certain number of plugins, but Zed avoids this. VS Code provides superior remote development support. It handles SSH, Dev Containers, and WSL with high stability. Zed’s remote development capabilities lack the same level of maturity. Users must manually specify port forwards in Zed. Users must also kill the application and restart it for SSH port forwards to function. This process disrupts the workflow for developers who work with multiple remotes. Will the Zed extension ecosystem ever reach the 50,000 mark of its competitor? Neovim provides an alternative for those who prefer a command-line interface. It is highly resource-efficient and works well on low-end machines. It allows for deep customization using Lua scripts. Developers working on large codebases should trial Zed’s performance.
