Zed — High-Performance Code Editor

Overview

Zed is an open-source editor built in Rust. Everything is configured with two JSON files that accept comments: settings.json and keymap.json (open them with the zed: open settings file and zed: open keymap commands; they live in ~/.config/zed/). Per-project overrides go in .zed/settings.json.

Names changed over the last year, so older blog posts and models get these wrong:

• the AI chat panel is the Agent Panel and its settings key is agent (not assistant); /file-style slash commands are replaced by @-mentions of files, symbols, threads and images;
• AI code completions are Edit Prediction, configured under edit_predictions (not inline_completions), toggled with editor::ToggleEditPrediction;
• theme accepts a name or { "mode": "system", "light": ..., "dark": ... };
• format_on_save is "on", "off", "modifications" or "modifications_if_available", and the default is "off";
• "disable_ai": true switches every AI feature off.

Check any key against the default settings file (zed: open default settings) before using it.
