Zed AI mode review: the Rust-based editor takes a real swing at AI

Zed is the Rust-based editor that promises native-app performance, collaborative editing as a first-class feature, and (since 2024) AI assistance baked in. By mid-2025 the AI side is real — not a gimmick, not an afterthought. After three weeks of using Zed as the primary editor on a side project, here is the working assessment.

What Zed actually is

A from-scratch code editor written in Rust, designed for performance from the GPU shader layer up. The editor itself is open source under GPL. AI features live in a Zed Pro tier ($10/month) and use Anthropic / OpenAI models with bring-your-own-key support.

What makes Zed distinctive vs. Cursor / Windsurf:

• Not a VS Code fork — designed from scratch
• Multi-buffer editing as a first-class concept — open multiple files in one buffer, search-replace across them, treat them as one virtual document
• Inline AI chat right in your buffer — the chat is in the editor, not a sidebar
• Collaboration baked in — multiplayer cursor, follow mode, voice chat

Where Zed wins

Editor performance is genuinely best-in-class. Even on huge codebases, scrolling, syntax highlighting, search are all noticeably faster than VS Code / Cursor. If you’ve ever felt VS Code chug on a million-line repo, Zed is the answer.

The AI is contextually aware in a different way. Zed’s AI chat can reference the multi-buffer you’ve assembled, so “explain how these three files interact” works naturally. Cursor / Windsurf require more manual context-stuffing.

Real OSS. Zed core is GPL, the Rust source is on GitHub, you can audit / fork / build yourself. For engineers in regulated environments or with provenance concerns, this is meaningful.

Native macOS feel. Like Arc browser before it (RIP), Zed on macOS feels like a native macOS app — not an Electron app pretending. Latency on input, animation smoothness, scroll feel — all noticeably better.

Where Zed loses

The honest constraints:

• Smaller extension ecosystem — Zed has its own extensions but the catalog is much smaller than VS Code’s. If you depend on a specific VS Code extension, check Zed’s catalog first.
• AI agent mode is less mature — Zed’s multi-file edits work but the agent loop is shorter / less autonomous than Cursor Composer or Claude Code.
• No tab completion at Cursor’s level — Zed’s autocomplete is good but not Cursor-tier. This may close with future development.
• Smaller community — fewer YouTube tutorials, fewer .zedrules patterns to copy, fewer Reddit threads on workflows.
• Linux support is improving — Zed on macOS is excellent; Linux is good but not as polished; Windows is in progress.

What the community says

The r/programming community signal:

• The DeltaDB discussion (103 ups) reflects engineers taking Zed’s engineering decisions seriously — even the contested ones
• Rainbow brackets thread (77 ups) — community appreciates the focused iteration
• The general pattern: engineers who have tried Zed respect it; switching is the harder threshold

How it fits in a 2025 stack

For our purposes:

• Cursor / Windsurf for primary AI-IDE work
• Claude Code in terminal for heavy agent tasks
• Zed as the editor of choice when working on a Rust project or when editor performance matters more than AI quality

The honest read: Zed is not yet a replacement for Cursor for AI-heavy daily work. It is a credible replacement for VS Code as a pure editor, with the AI as a bonus rather than the headline feature.

The recommendation

Try Zed if:

• You value editor performance and feel VS Code is slow
• You’re on macOS (best supported)
• You want an OSS editor with real AI integration
• You don’t depend heavily on specific VS Code extensions

Stay on Cursor / Windsurf if:

• You want the best AI experience first, editor performance second
• You have a VS Code extension stack you can’t replicate
• You’re on Windows (Zed support is still maturing)
