What is Zed?

Zed is a high-performance, collaborative code editor for multiple users, officially self-described as "Your last next editor". It is built by the authors of Atom and Tree-sitter. Unlike most editors based on Electron, it is written from scratch in Rust, which, according to the official, can fully utilize multiple CPU cores and GPUs to speed up the process. Zed places "humans" and "AI" in the same collaboration model: it allows real-time collaborative coding with teammates, screen and project sharing, and also enables AI agents to edit files in parallel, browse code and call tools. The official website has also launched Delta, a multi-user environment for "coding with agents".

Who is it for?

Developers who pursue the responsiveness of code editors and are tired of laggy experiences
Long-time users who already use Atom or value the syntax capabilities of Tree-sitter
Remote teams that need real-time pair programming and project sharing with teammates
Engineers who want AI agents to edit code in parallel and reduce repetitive manual work
Geeks who love open source and are willing to participate in the expansion ecosystem

Key features

Agentic Editing

The official claims that multiple agents can run in parallel to edit files, navigate code and run tools at native speed, leaving repetitive code modifications to the agents.

Edit Prediction

The edit prediction feature provides subsequent completion suggestions while writing code, reducing mechanical input based on the current context.

Inline Assistant

The in-line assistant answers questions and modifies code directly within the editor without switching to a separate chat window, preserving context.

Any Agent, Any Tool

The official claims it supports any agents and tools, integrating external AI capabilities into the editing workflow rather than being tied to a single model.

Real-time Collaboration

Chat with teammates, code together, and share screens and projects, making it ideal for distributed teams to work on the same files in parallel.

Language Services & Extensions

Supports LSP, Outline view and text/line operations, with an ever-growing extension ecosystem that covers daily editing needs.

How to use Zed

It is recommended to first download the version corresponding to your system (the official website provides macOS, Linux, and Windows versions).
Use the inline assistant for the first round of code Q&A and rewriting, then gradually try Agentic Editing to hand over large-scale refactoring to parallel agents.
Edit Prediction provides suggestions by default, and once you get used to it, you can use it as regular completion.
For collaboration scenarios, first create a shared project and invite teammates to the same file.
real-time collaboration is more efficient than sending patches back and forth.
Zed is an open-source editor, but its AI capabilities depend on the models and tools you configure.
Parallel agents will consume more context and quota, so it is recommended to run with a single agent first before enabling parallelism.
Platform functions and model access methods may be adjusted, so please check the official website instructions again before use.
