Category: High-Performance Code Editor
Platform: macOS, Linux (Windows beta)
Pricing: Free / Zed Pro (usage-based AI)
Built In: Rust, GPUI framework
Protocols: Agent Client Protocol (ACP), LSP
Key Features: Native speed, multiplayer, ACP agents, inline assistant

Zed is a from-scratch code editor built in Rust — faster than VS Code forks, with native multiplayer collaboration and first-class Agent Client Protocol (ACP) support. In 2026 it's the editor for developers who want performance and an open agent standard, not another Electron fork.

Agent Client Protocol

ACP is an open standard letting any agent (Claude Code, Codex, custom) plug into any ACP-compatible editor. Zed hosts agents natively — switch agents without switching editors. As the protocol matures, Zed becomes the neutral ground between vendor lock-in.

Key Strengths

Native performance — Rust + GPUI, sub-millisecond typing latency
Multiplayer — real-time collaborative editing built in
ACP agents — run Claude Code, Codex, or custom agents in-editor
Inline assistant — chat and edits without a side panel
Free core — editor is free; AI usage is usage-based

Tradeoffs

Smaller extension ecosystem than VS Code. Windows support still maturing. Best for early adopters who value speed and open protocols over extension breadth.
