Claude Code
Last updated June 29, 2026 · by Tal Gerafi
Claude Code is Anthropic's terminal-based AI coding agent: it reads your repository, runs commands, edits files, and verifies its own work in a loop — acting on a real codebase rather than handing you snippets to paste.
Claude Code runs in your terminal and works directly against your project. Instead of suggesting code you copy into an editor, it opens files, makes edits, runs your build or tests, reads the output, and corrects itself — the loop that distinguishes a coding agent from autocomplete.
How it works
You give it a task in plain language. It explores the relevant files, proposes or makes changes, and runs real commands to check them. Because it can see the actual repository and execute the actual build, its work is grounded in your codebase rather than a generic guess. Configuration files — an always-on CLAUDE.md, on-demand skills, hooks, and subagents — shape what it knows and how it behaves.
Why it matters for B2B sites
For a small team or a solo studio, Claude Code turns "I need an engineer for that" into "I can direct this and review it." The catch is supervision: an agent acting on a production codebase will eventually make a confident, wrong change, so the durable pattern is a human-in-the-loop review before anything ships. Used that way, it compresses the time from idea to live page without lowering the quality bar.
How does Claude Code compare to other coding tools?
| Tool type | What it does | Acts on your codebase? |
|---|---|---|
| Autocomplete (e.g. Copilot) | Suggests the next line as you type | No — you write and run the code |
| Chat assistant | Answers questions, returns snippets to paste | No — you copy code in by hand |
| Claude Code (coding agent) | Reads the repo, edits files, runs the build, fixes itself | Yes — end to end, in a loop |
The jump that matters is the loop: a coding agent closes the feedback cycle (act → check → correct) that autocomplete and chat leave to you.
FAQ
Is Claude Code free?
No — it is a paid tool from Anthropic, billed through a subscription or API usage. Whether it is worth the cost depends on how much real building you do; for a studio shipping sites continuously the time saved typically outweighs the spend, but validate it against your own usage.
Do you still need a developer to use Claude Code?
For anything production, yes. Claude Code does the building, but a person still directs the work and reviews it — the human-in-the-loop step is what keeps a confident, wrong change off a live site.
