Zed is a high-performance code editor built in Rust with GPU-accelerated UI rendering via the GPUI framework, designed for native speed, real-time multiplayer collaboration, and seamless AI integration. Developed by the creators of Atom and Tree-sitter, Zed runs on macOS, Linux, and Windows, offering sub-second startup times and minimal memory usage. The editor emphasizes developer productivity through built-in language server protocol support, integrated Git workflows, and first-class collaborative features like channels and multiplayer editing, enabling teams to work together in shared workspaces with near-zero latency. Understanding that Zed treats performance and collaboration as core design principlesβnot bolted-on featuresβhelps explain why it achieves 2x faster startup and 16x lower memory usage compared to Electron-based editors while simultaneously supporting real-time pair programming, AI-powered edit predictions, and agentic workflows that run at editor speed rather than network speed.

This topic spans 30 focused tables and 300 indexed concepts. Below is a complete table-by-table outline of this topic, spanning foundational concepts through advanced details.
Table 1: Real-Time Multiplayer Editing
| Feature | Example | Description |
|---|---|---|
Open Ctrl+Shift+C β Sign in to Zed account | Authentication required to access multiplayer features; supports GitHub OAuth or email sign-in. | |
Collaboration Panel β Click "Share" β Send invite link | Initiates real-time session; collaborators see live cursors and edits as they happen with CRDT-based conflict-free synchronization. | |
Click collaborator avatar β Your view follows theirs | Navigation follows the other person's viewport; useful for code reviews or pairing sessions. | |
Click "Unfollow" button or move cursor independently | Breaks viewport sync; both editors remain editable but navigation is independent. | |
Create channel β Add members β Shared projects auto-sync | Persistent rooms for team collaboration with voice chat, notes, and project access; think Slack for coding. |
