What is Claude Code?

Stefan Sånnell·23 March 2026·10 min
What is Claude Code?

Think of your computer as a house. The browser is the living room, where you spend most of your time. The terminal is the engine room. That's where the pipes, wires, and structure run. And it's where Claude Code lives.

It's not a chatbot you open in a browser tab. It's a tool installed directly in your project, that sees your files, understands your codebase, and can actually do things. Not suggest how to do them. Do them.

What that means in practice

Say you need to build a login page. It sounds simple. But in practice you need a form with the right fields, a backend endpoint to receive the data, a way to validate email format, encrypted password storage, session handling between page loads, redirect logic when it succeeds, and error handling when it doesn't.

That's six separate problems. Every experienced developer recognizes this. Most beginners see "login page" and don't understand what they've walked into until they're in the middle of it.

You can describe all of that to Claude Code. It handles it. It asks when it needs to make decisions about framework or structure. It builds, tests, fixes. You see every step as it happens.

Not a chat tool

There's an important distinction Stefan and Anders dwell on in the podcast: Claude Code isn't ChatGPT with coding ability. It's a tool built specifically to live inside your codebase.

That means it can read your files. It knows what's in your project. If you ask "why isn't the button working?", it doesn't just read the code you paste in. It examines the entire file structure, finds where the button is defined, traces which props it receives, and sees whether the problem is actually somewhere else than you thought.

That's the difference between asking a colleague who knows your project and a consultant seeing it for the first time.

The chef in your kitchen

Anders uses an analogy in the podcast that sticks: the copy-paste cycle is like trying to cook by photographing recipes from the internet and asking your assistant to read them aloud to you.

Claude Code is the chef in your kitchen. Not one calling in advice from outside. One who's actually there, stirring the pot, tasting, adjusting the temperature, and telling you if the recipe seems wrong.

That's the difference in presence. And that difference changes everything.

What happens when things go wrong

One of the more impressive things about Claude Code is what it does when something doesn't work. It doesn't stop at the error. It debugs.

It runs the code, reads the error message, examines the stack trace, forms a hypothesis about what caused it, tests the hypothesis, checks whether it was right, and iterates until it works or until it needs to ask you something it can't determine on its own.

It's not always perfect. But it's a completely different way of working than copying an error message to Google and guessing your way through Stack Overflow threads from 2017.

The architect and the builder

Stefan reasons through something important: Claude Code changes the role you play as someone commissioning code, but not away from understanding what you're building.

You still need to understand the architecture. You still need to understand what you're actually trying to accomplish. What you no longer need to do is be an expert in the syntax, toolchaining, and implementation details of every subcomponent.

The difference between an architect and a bricklayer. The architect knows what the building should do, how it should look, what it needs to withstand. The bricklayer knows how to lay bricks. Claude Code is a very competent bricklayer.

Software for one person

The closing argument that lingers longest: we're entering an era where you can build software for yourself.

Not for a market segment. Not for a product-meeting-defined user group. For you. A tool that handles exactly the workflow you actually have, with the rules that apply to your specific situation, integrated with the systems you actually use.

That's never been possible before. The cost of building a custom tool for one person was prohibitive. Now it's essentially zero, if you know what you want and can describe it.

Claude Code isn't the answer. It's the tool that lets you formulate the question.
