Zed

Zed is a next-generation code editor for macOS, built in Rust from the ground up for raw performance, collaborative editing, and deep AI integration — all without sacrificing the keyboard-first ergonomics that serious developers demand.

What is Zed?

Zed is a free, open-source code editor developed by Zed Industries — a team that includes creators of Atom and Tree-sitter — designed to be the fastest, most responsive editing environment available on macOS. It is not a rebuild of an existing editor, not Electron wrapped in a new skin, and not a VS Code fork. It is written entirely in Rust with a custom GPU-accelerated rendering engine, which is why opening a 50,000-line file in Zed feels like opening a text file, while the same operation makes other editors pause to breathe.

The first thing you notice is the silence. No spinner, no lag on keystroke, no janky autocomplete dropdown that appears half a second too late. The second thing you notice is how much thought has gone into making pair programming a first-class feature rather than an afterthought plugin.

What does Zed do best?

Zed's standout strength is speed that you feel in your hands rather than just in benchmarks. The GPU-rendered UI means the editor never drops a frame even on a large TypeScript monorepo or a Rust workspace with hundreds of crates. Tree-sitter parsing ships built-in for syntax highlighting and structural navigation, so folding, jumping to definitions, and selecting a function body are instantaneous.

Built-in multiplayer collaboration is the other headline feature. You invite a teammate via their GitHub account and get Google Docs-style real-time co-editing — cursors, selections, and keystrokes synced at near-zero latency without a paid subscription or a third-party extension. I used this regularly during a week of pair-programming sessions and found it noticeably snappier than Live Share in VS Code.

• GPU-accelerated rendering — no Electron, no DOM, no compositor overhead
• Tree-sitter everywhere — structural highlighting, precise text objects, incremental parsing
• Native LSP support — attach any language server; diagnostics appear inline without lag
• Built-in multiplayer — real-time collaborative editing baked into the core, not bolted on
• AI integration — first-party support for Claude, GPT-4, and local models via Ollama, with inline edit and full conversation panel
• Vim mode — not a simulation; it tracks upstream Neovim idioms closely enough that I rebind almost nothing

Is Zed free?

Yes — Zed is free to download and use with no feature paywall. The editor went open-source in early 2024 under a mix of GPL and AGPL licenses. AI features (Claude, GPT-4) may require your own API keys or a Zed Pro subscription for higher usage tiers, but the core editing experience, collaboration, and Language Server Protocol support are entirely free.

Who should use Zed?

Zed is the right fit for developers who have grown frustrated with the performance ceiling of Electron-based editors but do not want the configuration overhead of Neovim or Emacs. If you spend most of your day in VS Code and find yourself annoyed by extension bloat, sluggish autocomplete, or the way the editor stutters when you paste into a minified JSON file, Zed will feel like a pressure valve releasing.

It is also a natural fit for teams that pair-program regularly, since the built-in collaboration removes the need for screen-sharing plugins. That said, if your workflow depends heavily on a specific VS Code extension ecosystem — complex debugger UIs, niche language plugins, or a particular notebook integration — Zed's extension library is still maturing and you may hit gaps. I ran into this with a Jupyter workflow that had no clean equivalent yet.

What are the best Zed alternatives?

The closest alternative for raw performance on macOS is Neovim with a well-tuned config — terminal-native, extremely fast, and infinitely extensible, but it demands hours of configuration before it competes on features. VS Code remains the ecosystem king: unmatched extension breadth, solid remote development, and a massive community, but its Electron foundation puts a hard floor on responsiveness. JetBrains IDEs (IntelliJ, WebStorm, RustRover) offer the deepest language intelligence on the market but are paid, heavier, and slower to open. Cursor occupies an interesting middle ground — a VS Code fork with AI-first features — though it inherits VS Code's performance characteristics. For developers who want something lighter than JetBrains and faster than VS Code without going full Neovim, Zed is the obvious candidate to try first.

How does Zed compare to VS Code?

Zed starts faster, renders faster, and consumes significantly less memory under equivalent workloads — the gap is measurable even on Apple Silicon where VS Code performs better than on Intel. The trade-off is extension coverage: VS Code's marketplace dwarfs Zed's, and if you rely on specific debugger integrations or framework-specific plugins, you may need to wait for the ecosystem to catch up. VS Code also has a more mature settings UI and remote SSH editing story, though Zed is actively closing both gaps. For greenfield projects in languages Zed supports well (Rust, TypeScript, Python, Go, Ruby), the experience is simply tighter.
