Let’s be real, AI coding assistants are pretty much standard issue for developers these days. They’ve moved from a fun novelty to a tool that many of us rely on to get through the day. They can churn out boilerplate code, help untangle a gnarly function, or just act as a sounding board when you’re stuck.
But as useful as they are, getting them to play nice inside your code editor can feel like a whole separate project. You want an assistant that feels like a part of your workflow, not another window you have to constantly switch to.
This is where the combination of Claude Code and Visual Studio Code really starts to click. It’s a setup that turns one of the most popular editors on the planet into a smart, collaborative coding environment. This guide will walk you through everything you need to know about using VS Code Claude Code, from getting it installed to weaving it into your daily coding habits, and even sorting out those annoying setup snags.
What is VS Code Claude Code?
Before we jump into the setup, let’s quickly get on the same page about the tools we’re connecting. The VS Code Claude Code experience is all about making two great tools work as one, so let’s look at them individually first.
Understanding Visual Studio Code
If you’re a developer, you’ve almost certainly heard of Visual Studio Code, or just VS Code. It’s that free, open-source code editor from Microsoft that seems to have popped up everywhere over the last few years. Its popularity isn’t an accident, it’s fast, clean, and ridiculously customizable.
The real magic of VS Code is its massive marketplace of extensions. Whatever language, framework, or weird workflow you’re using, there’s probably an extension for it. This is the foundation that allows for a deep and genuinely useful integration like the one for Claude Code.
Understanding Claude Code
Claude Code is an AI coding assistant built by Anthropic. It’s designed to be more than just a fancy autocomplete. The goal here is to create a collaborative partner. Think of it less like a tool and more like a very keen junior developer who has read your entire codebase, understands the context of what you’re doing, and can write new files, edit existing ones, and even run terminal commands to get a job done.
Its main strength is that it’s "agentic." This just means you can give it a high-level goal, like "add a new API endpoint for user profiles," and it will figure out the smaller steps needed to actually make that happen.
How the VS Code Claude Code integration works
When we talk about VS Code Claude Code, we’re really talking about using the Claude Code AI agent without ever leaving your VS Code window. This is all handled by the official "Claude Code for VS Code" extension. It essentially puts a friendly, graphical interface on top of the command-line agent, giving you a nice chat panel right in your editor’s sidebar. You get all the power of the agent without having to constantly alt-tab to a terminal.

Getting started is usually pretty painless, but a few common issues can pop up, especially if you’re working with something like the Windows Subsystem for Linux (WSL). This section will give you a clear path to getting everything up and running smoothly.
Setup: The old way vs. the new way
It’s good to know that there have been a couple of ways to get this integration working. The original method was a "legacy CLI integration" that tried to hook into VS Code automatically when you ran the "claude" command in the built-in terminal. It was a bit clunky.
The new and much better method is the dedicated VS Code extension from Anthropic. It’s more stable, easier to use, and gives you a much richer interface to work with. We’re going to focus on setting up the new extension because, honestly, it’s the only way you should be doing it now.
Installation and initial setup
Getting this up and running just takes a few minutes. Follow these steps to get it right the first time.
-
Check your tools. First, make sure you have a recent version of VS Code installed (1.98.0 or newer is best). You’ll also need a Claude account with access to Claude Code, which comes with a Claude Pro, Max, Team, or Enterprise subscription. You can also use it with pay-as-you-go API credits.
-
Install the Claude Code CLI. The extension is just a user interface, so the command-line tool that does all the heavy lifting needs to be installed on your machine first.
-
Install the official extension. Open up VS Code, click on the Extensions icon (the one that looks like a puzzle piece), and search for "Claude Code." You’ll see a few results, so make sure you install the one published by Anthropic. There are some unofficial ones floating around that you’ll want to avoid.
-
Open the panel. Once it’s installed, a new Spark icon will appear in your VS Code sidebar. Click that, and the Claude Code panel will open up. You’re all set to start chatting.

As anyone who has scrolled through developer forums knows, setup isn’t always as simple as the instructions make it sound. Here are some of the most common headaches and how to fix them:
-
"No available IDEs detected." Ah, the classic. This one trips up a lot of people, especially if you’re using WSL. It basically means the Claude Code command-line tool can’t find your running instance of VS Code to talk to. The fix is usually to make sure the "code" command is available in your terminal’s PATH and that your Node.js versions are the same on your Windows host and your WSL environment.
-
The extension install fails. If the installation just hangs or gives you an error, it could be a permissions issue with VS Code. You can also try a manual install by downloading the ".vsix" file from the marketplace website and using the "Install from VSIX…" option in the Extensions view.
-
Can’t find the right extension. Seriously, double-check this one. The marketplace has a few knock-offs that use the Claude name but aren’t the real agentic tool from Anthropic. Look for the one published by "Anthropic."

Navigate to your project folder inside your WSL terminal and run the command "code .". This opens the folder in VS Code with the proper remote connection to WSL, which almost always solves the IDE detection problem.">
Core features and daily workflows
Alright, you’re all set up. Now for the fun part: actually using it to make your life easier. Here’s a look at what the integration can do and how you can fit it into your day-to-day coding.
Key features
This isn’t just a chatbot in a sidebar. The integration has some genuinely useful features that are worth knowing about.
-
Dedicated Sidebar: The chat panel stays open and keeps your conversation history. This might sound small, but being able to scroll back through a long problem-solving session without hunting through terminal logs is a huge convenience.
-
Inline Diffs: This is probably my favorite feature. When Claude suggests a code change, it doesn’t just dump a code block in the chat. It shows you the change directly in your editor as an inline diff, just like you’d see in a Git client. You can see exactly what’s being added or removed, make your own edits on top of it, and accept the change with a single click.

This context is automatically sent along with your prompts. So, you can just highlight a buggy function and type "Fix this" instead of having to copy and paste the code into the chat. It’s a small thing that saves a ton of friction.

@-mentioningthem in your prompt. And, after you give it permission, it can run terminal commands. This means it can do things like install dependencies, run your test suite, or lint the code it just wrote.

You can use this integration in a couple of ways, and you’ll likely switch between them depending on what you’re working on.
-
The Pair Programmer: This is the most common way to use it. You have an ongoing conversation with Claude in the sidebar. You can ask it to brainstorm ideas for a new feature, write a function from scratch, explain a chunk of legacy code you’re afraid to touch, or help you figure out why a test is failing. It’s a collaborative back-and-forth where you’re in the driver’s seat.
-
The Autonomous Coder: For bigger, more tedious tasks, you can let Claude take the lead. For instance, you could give it a prompt like, "Refactor this entire module from JavaScript to TypeScript and then write unit tests for all the exported functions." Claude will create a plan, show it to you for approval, and then get to work, making changes file by file. You can sit back and watch its progress, reviewing the diffs as it creates them.
-
Integrated vs. Split View: Here’s a workflow I’ve seen a few people adopt: they let Claude run autonomously in a separate terminal window, but use VS Code purely for reviewing the changes it makes. VS Code’s built-in source control tools provide a great interface for viewing and staging a large number of changes, which can be a bit easier to manage for big refactoring jobs than the live inline diffs.
This video provides a deep dive into how you can get started with Claude Code inside your VS Code environment.
VS Code Claude Code: Advanced capabilities, limitations, and alternatives
The VS Code Claude Code setup is impressive, but it’s still just a tool. It’s important to know where it excels, where it falls short, and how it compares to the other options out there.
Advanced features
Once you get the hang of the basics, there are a few power-user features you can explore for more complex tasks.
-
Checkpoints: This is a lifesaver. Claude can automatically save a snapshot of your code before it makes a big change. If you see it heading in the wrong direction, you can tell it to rewind to the last checkpoint and try a different approach, without having to manually undo a bunch of files.
-
Subagents: For really huge tasks, like building a whole new feature from the ground up, you can configure Claude Code to delegate parts of the job to specialized subagents. You could have one agent working on the frontend components while another stubs out the backend API, letting them work in parallel.
-
Hooks: You can set up custom hooks to trigger actions at certain points. A common one is to create a hook that automatically runs your entire test suite every time Claude finishes a block of work, giving you instant feedback on whether the changes introduced any regressions.

This agentic coding stuff can feel like magic sometimes, but it’s not infallible. It’s a tool that works best when guided by a skilled developer.
You still need to write clear, specific prompts. As many folks on platforms like Hacker News have noted, the quality of the AI’s output is directly proportional to the quality of your instructions. If you give it a vague, one-line request for a complex feature, you’re probably going to get a vague, buggy result. It can still get stuck on highly original problems, and it will occasionally produce code that works but isn’t very efficient. It’s best to think of it as a very fast and knowledgeable junior dev, not a substitute for a senior engineer’s judgment.
How VS Code Claude Code stacks up against other tools
The world of AI coding assistants is getting crowded fast. Here’s a quick rundown of how the Claude Code setup compares to a couple of the other big names.

| Pricing Model | Requires Claude Subscription or API credits | Requires Copilot Subscription | Requires Cursor Subscription |
VS Code Claude Code pricing
As you might have guessed, using the VS Code Claude Code integration isn’t free. Your usage is tied directly to your Anthropic account.
To get it working, you’ll need an active Claude Pro, Max, Team, or Enterprise subscription. If you don’t have a subscription, you can also use it with pay-as-you-go API pricing. For the latest numbers, your best bet is to always check the official Claude pricing page.
Automating development with VS Code Claude Code and looking ahead
The VS Code Claude Code integration is a fantastic way to bring agentic AI into your daily coding workflow. It goes way beyond simple code completion, letting you collaborate with an AI on genuinely complex problems right inside the editor you already use. It has a bit of a learning curve and absolutely needs a human in the loop, but it has the potential to seriously speed up your development process.
This trend of agentic AI isn’t stopping with software development, either. The same ideas about automating complex, knowledge-based work are showing up in other areas, especially in customer support and internal IT helpdesks.
And that’s where a tool like eesel AI enters the picture. It’s built to bring this same power to your entire company, not just the engineering team.
