Zed

Zed is a code editor built from scratch in Rust by the team behind Atom and Tree-sitter. It renders on the GPU, starts instantly, and stays responsive on large files — performance is the founding premise, not a later optimisation.

What it offers

• Speed you can feel. Sub-millisecond input latency, fast search, and no perceptible lag when navigating big repositories.
• Agents as a first-class feature. Run agentic coding sessions inside the editor with your choice of model, including external agents such as Claude Code and Codex through the Agent Client Protocol. Multiple agents can work in parallel threads.
• Edit prediction. A model trained for the task suggests the next edit, not just the next token, which is a better fit for refactoring than plain completion.
• Real-time collaboration. Share a project, edit together, and talk over voice — built in, not an extension.
• Language support through Tree-sitter parsing and LSP, with an extension ecosystem for languages, themes, and tooling.

Availability

Zed is open source and free for the editor itself, on macOS, Linux, and Windows. Paid plans cover hosted model usage if you do not want to bring your own API key.
