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 principles—not bolted-on features—helps 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.

Table 1: Real-Time Multiplayer Editing
Collaboration is built into Zed's core, not bolted on as a plugin — sign in, share a project, and your teammates see your cursor and edits live thanks to conflict-free (CRDT) synchronization. The features here range from the lightweight (following a colleague's viewport during a review) to the full pairing setup with voice chat and screen sharing, all without ever opening Zoom or Slack alongside your editor.
| Feature | Example | Description | |
|---|---|---|---|
Open Ctrl+Shift+C → Sign in to Zed account | • Authentication required to access multiplayer features • supports GitHub OAuth or email sign-in | ||
Collaboration Panel → Click "Share" → 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 → 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 → Add members → Shared projects auto-sync | • Persistent rooms for team collaboration with voice chat, notes, and project access • think Slack for coding | ||
Join channel → Enable microphone for audio call | • Real-time voice communication during pairing • integrates natively without external tools | ||
Click "Share Screen" → Select window or display | • Share your screen with channel members • no Zoom or Meet required for quick demos | ||
Open channel notes → Edit Markdown collaboratively | Shared scratchpad for design docs, todos, or meeting notes inside channels. | ||
Each collaborator keeps own screen/keyboard/mouse | • Multiple people in same project with independent viewports • different from screen-share mode | ||
Changes auto-reflect in collaborator's UI instantly | • Version control state syncs in real-time • all participants see unstaged/staged changes simultaneously |
