title: Run and Test Code in Zed description: Run and test code in Zed with Terminal, Tasks, REPL, and debugger workflows without leaving the editor.

Running & Testing

Use this section to run and test code in Zed, then debug issues without leaving the editor.

What's here

• Terminal: Zed's built-in terminal emulator. Open multiple terminals, customize your shell, and integrate with the editor. Tasks and commands run here.

• Tasks: Define and run shell commands with access to editor context like the current file, selection, or symbol. Use tasks to build, lint, run scripts, or execute any repeatable workflow.

• Debugger: Set breakpoints, step through code, and inspect variables using Zed's built-in debugger. Works with C, C++, Go, JavaScript, Python, Rust, TypeScript, and more through the Debug Adapter Protocol.

• REPL: Run code interactively using Jupyter kernels. Execute selections or cells and see results inline—useful for Python, TypeScript (Deno), R, Julia, and other supported languages.

Quick start

Open a terminal: Press Ctrl+` to toggle the terminal panel, or Ctrl+~ to open a new terminal.

Run a command: Press Cmd+Shift+R (macOS) or Ctrl+Shift+R (Linux/Windows) to open the task picker, then type any shell command.

Start debugging: Press Cmd+Shift+D (macOS) or Ctrl+Shift+D (Linux/Windows) to open the debug panel and select a configuration.

Run code interactively: In a Python or TypeScript file, select some code and press Ctrl+Shift+Enter to execute it in a REPL session.
