Coding Free (open source) — BYOK for AI features ★ Editor's pick

Zed

Rust-built code editor with native AI agents, edit prediction, and real-time collaboration — all at native speed that makes Electron editors feel sluggish.

Overview

Zed is a high-performance code editor built from the ground up in Rust by the team behind Atom and Tree-sitter. It reached 1.0 in late April 2026 with a clear thesis: a code editor should feel instant, and AI should be a first-class citizen rather than a bolted-on extension. The result is an editor that launches in milliseconds, scrolls without jank, and treats AI agent workflows as core functionality.

The standout feature at 1.0 is Parallel Agents — you can spin up multiple AI agents working on different parts of your codebase simultaneously. While one agent refactors a module, another can be writing tests for a different file. Edit prediction goes beyond autocomplete: Zed anticipates multi-cursor edits, structural changes, and repetitive patterns before you type them. It feels less like tab-completion and more like the editor reading your mind.

Where Zed differs from Cursor and Windsurf is its BYOK (bring your own key) approach. There's no built-in AI subscription — you connect your own API keys from Anthropic, OpenAI, or other providers. This means you control costs and model choice directly, but it also means there's more setup friction compared to editors that bundle AI credits. The real-time collaboration features, inherited from the team's experience building Atom, are genuinely excellent — think Google Docs for code, with shared cursors and voice chat built in.

Key features

Parallel AI Agents

Run multiple AI agents simultaneously across your codebase. Each agent operates independently — one can refactor a module while another writes tests or updates documentation. No waiting for sequential completions.

Edit Prediction

Goes beyond autocomplete to predict structural edits, multi-cursor changes, and repetitive patterns. Learns from your editing behavior within a session to anticipate what you'll do next.

Real-time Collaboration

Built-in multiplayer editing with shared cursors, project-wide navigation, and integrated voice chat. No extensions or third-party services needed — collaboration is part of the editor core.

Native Performance

Written entirely in Rust with a custom GPU-accelerated UI framework (GPUI). Sub-millisecond keystroke latency, instant file switching, and smooth scrolling even in massive files.

Pricing

Free tier: Fully free and open source. AI features require your own API keys from model providers.

Zed Editor Free

Full editor, extensions, collaboration, terminal, AI agent support — open source (GPL/AGPL)

AI Features BYOK

Connect your own API keys from Anthropic, OpenAI, Google, or other providers. You pay providers directly at their rates.

Pros & cons

Pros

  • Exceptional speed — fastest modern code editor available, with sub-millisecond input latency
  • Parallel agents let you run multiple AI tasks at once without blocking your workflow
  • No AI subscription lock-in — use any model provider with your own API keys
  • Built-in real-time collaboration with voice chat, no extensions needed

Cons

  • ×Smaller extension ecosystem compared to VS Code-based editors like Cursor
  • ×BYOK model means more setup friction — you need API keys before AI features work
  • ×No Windows support yet — currently macOS and Linux only
  • ×Fewer built-in language integrations than mature IDEs like JetBrains
