## Summary

Zed is a Rust-built code editor by ex-Atom creators with instant startup, 120fps scrolling, real-time multiplayer editing, and built-in AI assistance — a faster alternative to VS Code.

## Company Overview

Zed is a San Francisco-based code editor company building a high-performance, multiplayer code editor in Rust that aims to be significantly faster than Electron-based editors like VS Code while offering built-in real-time collaboration and AI assistance. Zed's Rust implementation enables near-instant startup, smooth scrolling at 120fps, and no performance degradation in large codebases where VS Code slows down. The editor's real-time collaboration feature allows multiple developers to edit the same file simultaneously with conflict-free synchronization — similar to Google Docs for code. Zed integrates AI assistance through a built-in language model interface that can explain code, generate completions, and refactor functions without switching to a separate tool. The company was founded by the creators of Atom (the open-source editor acquired by GitHub) and Tree-sitter (a parser generator). Zed raised over $26M from investors including Andreessen Horowitz and launched as an open-source project in 2024, driving rapid adoption among performance-conscious developers. It competes with VS Code, Neovim, and JetBrains IDEs.

## Frequently Asked Questions

### Why is Zed faster than VS Code?
Zed is written in Rust and rendered with a custom GPU-accelerated UI framework rather than being built on Electron (which runs Chromium), eliminating the performance overhead of a full browser engine and enabling startup times under 100ms and smooth scrolling in large codebases.

### What is Zed?
Zed is a high-performance code editor built in Rust with real-time collaborative editing and built-in AI assistance, designed to be significantly faster than Electron-based editors like VS Code while offering multiplayer coding and language model integration.

### Who founded Zed?
Zed was founded by Nathan Sobo and Antonio Scandurra — creators of GitHub's Atom editor — along with Max Brunsfeld. After Atom was sunset by GitHub in 2022, the founders built Zed as a next-generation editor with performance and collaboration as core design principles.

### How does Zed's real-time collaboration work?
Zed allows multiple developers to edit the same file simultaneously with conflict-free synchronization using a CRDT (Conflict-free Replicated Data Type) algorithm, similar to Google Docs co-editing but for code — with each collaborator's cursor and changes visible in real time.

### Is Zed open source?
Yes. Zed became open-source in January 2024 under the GPL, Apache 2.0, and AGPL licenses depending on the component. The core editor is open-source and can be built from source, while Zed's cloud collaboration features are part of the commercial service.

### Does Zed support extensions and language servers?
Yes. Zed supports Language Server Protocol (LSP) for language intelligence features like autocomplete, go-to-definition, and error highlighting across dozens of programming languages, and has a growing extension ecosystem for themes, additional language support, and tooling integrations.

### What AI features does Zed include?
Zed integrates AI assistance through a built-in language model interface that supports multiple providers including Anthropic Claude and OpenAI, providing inline completions, code explanation, refactoring suggestions, and a chat interface — all within the editor without switching to a separate tool.

### What platforms does Zed support?
Zed currently supports macOS and Linux. A Windows version has been in development, with the Rust-based architecture making cross-platform support technically feasible. The editor is available free of charge for individual use.
