What is Claude Code in simple terms?

Claude Code is a command-line tool from Anthropic that lets engineers work alongside Claude inside their terminal. You start it in your project directory, ask Claude to do something (fix a bug, refactor a module, write a new feature, run the tests), and Claude reads the files it needs, makes the edits, runs the commands, and reports back. It is the closest thing to having a junior engineer working alongside you on the codebase.

Who is Claude Code for?

Claude Code is for any engineering team that lives in the terminal and wants AI doing real work, not just suggesting completions. It works for solo engineers, small in-house engineering teams at SMBs, and large dev teams that need autonomous coding work alongside their existing IDE setup. It is less suitable for engineers who never leave their IDE - for those, Cursor or GitHub Copilot is the better fit.

How much does Claude Code cost?

Claude Code access is bundled with Claude.ai subscriptions. Claude.ai Pro at US$20/user/month is the minimum tier; Claude.ai Teams at US$25-30/user/month gives shared access alongside the Projects and Skills features for the rest of the business. Higher Claude.ai tiers unlock larger usage allowances. There is no separate Claude Code line item.

Is Claude Code better than Cursor or GitHub Copilot?

It is different. Claude Code is the strongest tool for long-running autonomous coding work - large refactors, multi-file changes, codebase-wide migrations - because it runs as an agent in your terminal rather than as completions inside your editor. Cursor is the strongest AI-first IDE. GitHub Copilot is the strongest in-editor autocomplete. Most SMB engineering teams we work with end up running two or three of them in parallel.

Can a non-engineer use Claude Code?

Technically yes - the tool is designed to be approachable - but practically Claude Code is built for people who already understand a codebase. Non-engineers who want to ship software get more value from no-code tools like Lovable, or from working with an engineer who uses Claude Code on their behalf. For business users, the right Anthropic product is Claude.ai (the chat interface) not Claude Code.

Does Claude Code see our source code?

It reads the files in the directory you launch it from, sends them to the Anthropic API for the duration of the conversation, and Anthropic does not train its models on Claude Code usage when you are on a paid Pro/Teams/Enterprise tier. If you have strict data-handling rules around source code (NDA-restricted client code, regulated IP), restrict where Claude Code can be launched and review the relevant clauses in Anthropic's data policy with your legal team.

What is Claude Code? A plain-English primer for SMB owners

Claude Code is the most talked-about Anthropic product in 2026 outside Claude itself, and yet most SMB owners we work with have no clear picture of what it actually is. This is the plain-English primer: what Claude Code does, who it is for, what it costs, and whether your business should care.

The 30-word definition

Claude Code is Anthropic’s command-line coding assistant. Engineers run it in their terminal, point it at a codebase, and Claude reads files, edits code, runs tests and ships work alongside them.

How it works in practice

A typical session looks like this. An engineer opens their terminal in a project directory, runs claude, and asks Claude something like “the login flow is broken when the email contains a plus sign, can you find and fix it?” Claude reads the relevant files, traces the bug, makes the edit, runs the existing tests, reports back what changed and why.

Unlike chat-based coding assistants, Claude Code is designed to act in the real environment - opening files, editing them in place, running commands, navigating the codebase the way a human engineer would. It is an agent, not a chat window.

What it is good for

Long-running engineering work: large refactors, multi-file migrations, codebase-wide rewrites
Bug investigations that require reading many files to trace a problem
Writing tests against an existing codebase that lacks them
Building a new feature that has to fit existing conventions
Routine engineering work that an experienced engineer can spec but does not need to write personally

What it is not good for

Engineers who never leave their IDE - the terminal-first workflow is the friction point. Use Cursor instead.
Non-engineering staff who want to ship software. Use Lovable, Bolt or similar instead.
Greenfield projects with no codebase to read - Claude Code shines when there is context to ground its decisions in.
Workflows that need GUI interaction (drag-drop, visual editing).

What it costs

Claude Code access is bundled with Claude.ai subscriptions, not separately priced:

Claude.ai Pro (US$20/month) - minimum tier with Claude Code access
Claude.ai Teams (US$25-30/seat/month) - shared with the rest of the business stack
Claude.ai Enterprise (custom pricing) - with admin controls and higher usage limits

Higher tiers unlock larger usage allowances. For a typical Australian SMB engineering team, Claude.ai Teams is the right tier - it covers Claude Code for engineers and Claude.ai for the rest of the business under one subscription.

How it compares to Cursor and Copilot

The short version: Claude Code is the strongest tool for long-running autonomous engineering work, Cursor is the strongest AI-first IDE for in-editor work, and GitHub Copilot is the strongest in-IDE autocomplete with enterprise governance. They do different jobs, and most teams we work with run two of them in parallel.

For a deeper comparison see our piece on Cursor vs Claude Code vs Copilot.

Should our business use it?

If you have an in-house engineering team of any size, yes - Claude Code is the highest-leverage AI tool we have seen for engineering productivity. Typical uplifts are 30-50% on routine work and meaningfully more on long-running migrations and refactors.

If you do not have an engineering team, Claude Code is not the right starting point. The equivalent leverage for the non-engineering side of an SMB is Claude.ai Teams with Projects for operations, sales, marketing and finance staff. Build that first; add Claude Code later if and when engineering needs grow.
