Zed
GPU-accelerated Rust code editor by Atom's creators - real-time multiplayer editing, AI Edit Prediction via Zeta2, $32M Series B from Sequoia.
Zed is a high-performance, GPU-accelerated code editor built in Rust by Antonio Ferrante and Nathan Sobo - the original authors of Atom and Tree-sitter. It combines native-speed performance (no Electron overhead) with deeply integrated AI assistance and real-time multiplayer collaboration as core features, not plugins. Zed open-sourced its full codebase on January 24, 2024, added Linux support in July 2024, and raised a $32M Series B led by Sequoia Capital in August 2025. The AI layer centers on Edit Prediction using Zeta2 - Zed's own open-weight model that anticipates the next edit rather than just completing the current line. The Business plan at $30/seat/month adds org-wide AI model governance and data controls for enterprise teams.
Key Features
- Edit Prediction using Zeta2 - Zed's own open-weight model anticipates next edits, not just completions; 2,000 accepted predictions/month on free tier
- Parallel Agents - run multiple AI agent threads across different projects simultaneously from a single editor window
- Native Debugger built on DAP (Debug Adapter Protocol) with multi-language support - no extension required
- Multibuffer Editing - compose excerpts from multiple files across the codebase into a single editable surface
- Real-time multiplayer collaboration - live cursors and shared editing built into the editor core, not a plugin
- Remote Development - UI renders locally while the codebase executes on a remote server with full LSP support
- First-class Git integration - stage, commit, pull, push, and inline diffs without leaving the editor
Use Cases
- Developers who find VS Code too slow or resource-heavy and want a native-performance editor with AI built into the core rather than bolted on
- Engineering teams pair-programming remotely who need real-time collaborative editing without the latency of web-based IDEs
- Engineers running remote development on cloud VMs while keeping the local editing experience fast and keyboard-driven
- Developers running multiple AI agent tasks in parallel across separate projects from a single editor window
Pros
- GPU-accelerated Rust architecture delivers response times that feel native - no Electron overhead or Node.js startup latency
- Zeta2 Edit Prediction uses your own API keys on the free plan - AI features without a mandatory subscription beyond $0
- Real-time multiplayer collaboration and remote development are built into the core - not third-party extensions that break on updates
Cons
- macOS and Linux only as of 2026 - no Windows support excludes a significant portion of the developer market
- Plugin ecosystem is tiny compared to VS Code's 50,000+ extensions - niche language and framework tooling is often unavailable
- $30/seat/month Business plan is expensive for teams that could get AI governance through GitHub Copilot Business at a lower per-seat cost
