# How to Use Claude Code in VS Code: Install, Inline Diffs, and When to Stay in the Terminal

> Install the Anthropic extension, open a file, click the Spark icon, and sign in with a paid Claude account — the panel bundles its own CLI, so there's nothing else to set up.

## Key takeaways

- To use Claude Code in VS Code, install the official Anthropic extension from the Marketplace, open a file, click the Spark icon in the editor toolbar, and sign in with a paid Claude subscription (Pro, Max, Team, or Enterprise) or a Console account.
- The extension bundles its own copy of the Claude Code CLI, so you do not need to install Node or the CLI separately just to use the graphical panel.
- Inside VS Code you get inline diffs in the native diff viewer, accept/reject on edits, automatic sharing of your selected code, plan mode that opens as an editable Markdown document, and a panel you can dock in the sidebar or as a tab.
- You only need the separate standalone CLI install to run the `claude` command in the integrated terminal or to use CLI-only features.

## At a glance

| What you're doing | In the VS Code extension | In the terminal CLI |
| --- | --- | --- |
| Reviewing an edit | Inline diff in VS Code's native diff viewer — accept, reject, or tweak in place | Unified diff printed in the terminal; approve at the prompt |
| Sharing code context | Automatic from your editor selection; Option/Alt+K inserts an @file#5-10 range | @-mention files by path; there is no editor selection to read |
| Planning a change | Plan mode opens as an editable Markdown doc with inline comments | Plan is printed inline; approve to proceed |
| Slash commands and skills | A subset of the command set; no ! bash shortcut or tab completion | Full command set, the ! bash shortcut, and tab completion |
| Piping and CI runs | Not available in the panel | Native — pipe logs into claude -p in any shell, or run headless in CI |
| The claude command on PATH | Not added; the bundled CLI is private to the panel | Installed on PATH via the standalone setup |

If you searched "claude code vscode," here's the whole answer: install the official **Claude Code** extension (publisher: Anthropic) from the VS Code Marketplace, open a file, click the **Spark icon** in the top-right editor toolbar, and sign in with a paid Claude account. The extension ships with its own copy of the Claude Code CLI, so that's genuinely all it takes — no Node install, no separate CLI, no API key.
That last part is what most older tutorials get wrong: the graphical panel is self-contained. You only need a separate install for the `claude` command in your terminal — covered at the end.
Prerequisites
- **VS Code 1.94.0 or higher** (Help → About to check). The extension also installs in forks like [Cursor](/stack/cursor) via Open VSX.
- **A paid Claude account**: any Claude subscription (Pro, Max, Team, or Enterprise) *or* a Claude Console account. **No API key required** — you sign in through the browser. The free Claude.ai plan does not include Claude Code.
- **Nothing else for the panel.** The extension bundles the CLI it needs. Node.js is *not* a prerequisite; it only matters if you later install the standalone CLI via npm (which wants Node 22+), and even the native installer ships a binary that doesn't use Node.
- *Optional:* the standalone Claude Code CLI, if you want to run `claude` in the integrated terminal.

1. Install the extension
**The Marketplace path.** In VS Code, press `Cmd+Shift+X` (Mac) or `Ctrl+Shift+X` (Windows/Linux) to open the Extensions view, search **Claude Code**, confirm the publisher is **Anthropic**, and click **Install**. Or use the direct link `vscode:extension/anthropic.claude-code`. If the extension doesn't appear afterward, run **Developer: Reload Window** from the Command Palette.
**The `claude` auto-install path.** If you already have the standalone CLI, you don't have to touch the Marketplace. Open VS Code's integrated terminal and run:
```
claude
```
Running `claude` inside a VS Code terminal auto-installs the IDE extension for you. If you'd rather it didn't, turn off **Auto-install IDE extension** in `/config`, set `autoInstallIdeExtension` to `false`, or set the `CLAUDE_CODE_IDE_SKIP_AUTO_INSTALL` environment variable to `1`.
The first time you open the panel, a sign-in screen appears. Click **Sign in** and finish authorization in your browser.
2. What changes vs. the terminal
Running Claude Code *inside* the editor buys you a real GUI on top of the same engine:
- **Inline diffs.** When Claude wants to edit a file in **Manual** mode, it opens a side-by-side comparison in VS Code's native diff viewer and asks permission. You can **accept, reject, or tell Claude what to do instead** — and if you tweak the proposed change directly in the diff before accepting, Claude is told you modified it.
- **Automatic selection sharing.** Highlight code and Claude sees it automatically; the prompt box footer shows how many lines are selected. Press `Option+K` (Mac) / `Alt+K` (Windows/Linux) to insert an `@`-mention with the exact range, like `@app.ts#5-10`. `@`-mention any file or folder with fuzzy matching.
- **Plan mode you can edit.** In **Plan** mode Claude describes its approach and waits. VS Code opens that plan as a **full Markdown document with inline comments**, so you steer the work *before* a single line changes — the single best habit for non-trivial tasks.
- **A panel that lives where you want it.** Dock Claude in the secondary sidebar to keep it visible while you code, or open it as an editor tab for side tasks. Session history, multiple parallel conversations in tabs, and checkpoint rewind are all there.

Under the hood, a small local `ide` [MCP server](/topics/mcp) is what opens those diffs, reads your selection, and pulls language-server diagnostics.
3. The everyday workflow
The loop is short:
- **Open the file** you're working in. Click the Spark icon (top-right of the editor) to open the panel. `Cmd+Esc` / `Ctrl+Esc` toggles focus between editor and Claude.
- **Point at the code.** Select the lines in question and press `Option+K` / `Alt+K` to attach them as a reference, or just `@`-mention a file.
- **Ask** in plain language: "why does this throw on an empty array?" or "add pagination to this endpoint."
- **Review the diff** and accept or reject. `Cmd+Shift+Esc` / `Ctrl+Shift+Esc` opens a fresh conversation in a new tab when you want to keep tasks separate.

One honest heads-up for solo builders: on Pro, Max, and Team plans the panel *starts in Auto mode*, where a classifier approves most edits instead of you. That's fast, but Claude changes files without asking by default. Click the mode indicator at the bottom of the prompt box and switch to **Manual** when you want to eyeball every diff — for instance when Claude is touching config files VS Code executes automatically. (Keeping a long session's context clean is its own skill; see [how to manage context in a long-running agent](/posts/how-to-manage-context-in-a-long-running-agent.html).)
4. When to stay in the terminal instead
The extension exposes a *subset* of Claude Code. Drop to the CLI when you hit its edges:
- **CLI-only commands and skills.** Type `/` in the panel to see what's available; it's a subset of the full command set. The `!` bash shortcut and tab completion are terminal-only.
- **Piping and automation.** Headless runs like `tail -200 app.log | claude -p "flag anomalies"` or `claude -p` in CI belong in a shell, not a chat panel.
- **Background processes.** The extension's visibility into long-running tasks is limited; the terminal shows more.

To run the CLI without leaving VS Code, open the integrated terminal (`Ctrl+`` / `Cmd+``) and run `claude`. The catch worth repeating: **installing the extension does not put `claude` on your PATH** — the bundled copy is private to the panel. You need the standalone install (`curl -fsSL https://claude.ai/install.sh | bash` on macOS/Linux) for the terminal command. From an *external* terminal, run `/ide` inside Claude to connect back to VS Code for diff viewing.
Extension and CLI share the same history, so `claude --resume` picks up a panel conversation and vice versa. Use the panel to review and shape changes; use the terminal for scripting and scale. For picking the model underneath, our [open-source LLM for coding roundup](/posts/open-source-llm-for-coding-september-2026.html) covers the local alternatives.

## FAQ

### Do I need to install the Claude Code CLI separately to use the VS Code extension?

No. The extension bundles its own copy of the CLI for the chat panel. You only need the standalone CLI install if you want to run `claude` in VS Code's integrated terminal, since the extension does not add `claude` to your PATH.

### Do I need an API key to use Claude Code in VS Code?

No API key is required. Any paid Claude subscription (Pro, Max, Team, or Enterprise) or a Claude Console account works, and you sign in through your browser the first time you open the panel. The free Claude.ai plan does not include Claude Code.

### How do I open Claude Code once the extension is installed?

Open a file and click the Spark icon in the top-right editor toolbar, click the Spark icon in the Activity Bar, or open the Command Palette (Cmd/Ctrl+Shift+P) and run a 'Claude Code' command like Open in New Tab. Cmd/Ctrl+Esc toggles focus between the editor and the panel.

### What is plan mode in the VS Code extension?

In plan mode Claude describes what it intends to do and waits for approval before making changes. VS Code opens the plan as a full Markdown document where you can add inline comments to give feedback before Claude starts writing code.
