Short answer
Zed works with Ruby the way it works with most languages: blazing fast Rust core. The catch is smaller extension ecosystem than VS Code.
Language-specific notes
Ruby / Rails is a first-class citizen for most AI tools due to convention-heavy codebases.
Setup for Ruby
- Install Zed from zed.dev
- Open your Ruby project
- If you use MCP servers, add them via the settings pane
