The tool, explained
It's mentioned on every page of this site. Here's what it actually is — in plain English, with a picture of what using it looks like.
Claude Code is an AI coding tool made by Anthropic. It runs in your terminal — the plain text window on your computer — and it does what a software developer does: writes code, creates files, sets up databases, fixes errors, and explains its work. The difference is how you direct it. There's no programming language to learn. You tell it what you want in plain English, and it does the work in front of you.
Think of it as a developer who can read a 200-page blueprint and build everything in it, step by step, asking you to review before moving on. That's exactly how it works with a Build Pack: the pack is the blueprint — architecture, database design, build order, all decided — and Claude Code executes it stage by stage while you approve each step. It's the reason a non-technical owner can build a production platform in days.
> Read CLAUDE.md and SETUP.md, then build this platform stage by stage. Pause after each stage so I can review. ● I've read the project brief. This is a client-intake platform with 14 database tables, login, and an admin dashboard. Starting Stage 1: authentication and user accounts. Created app/login/page.tsx Created lib/auth.ts Database: users table added ● Stage 1 complete. Users can register, log in, and reset passwords. Want to see it running before I continue? > yes, show me ● Running at http://localhost:3000 — open that in your browser. When you're happy, say "continue" and I'll start Stage 2: the core data model.
The > lines are you — typed in plain English. Everything else is Claude Code working and reporting back.
You type sentences: “build the next stage,” “explain what this page does,” “make the buttons green,” “something broke — fix it.” It answers in sentences too, and shows you what it changed. If you can write an email, you can direct Claude Code.
Claude Code is made by Anthropic and billed by them — a Claude Pro subscription (about $20/month) covers typical build sessions, or you can pay per use via their API. Expect a platform build to cost less than a nice dinner. Anthropic's pricing →
Claude Code is at its best when it has a complete plan to execute — that's what a Build Pack is. Pick the market you understand, and let the two of them get to work.
