No agency, no template, no developer. Every page, the design system, the nine deliverables, and the interactive cost calculator were built with Claude, in a day — directed by an HR operator, not an engineer. Here’s exactly how, and exactly what it costs.
I’m not a developer. I worked in Claude Code, in the Claude desktop app — describing each page in plain language, and Claude wrote the HTML and CSS, built the design system, and shipped the interactive tools. I reviewed, redirected, and decided; Claude did the building.
The whole site is static HTML: no framework, no build step, no dependencies. The cost-model calculator — live recompute, export to a real Excel file — runs on a few hundred lines of hand-rolled JavaScript with zero libraries; Claude even wrote the in-browser spreadsheet writer. The same goes for the nine deliverables in the library: each one built, fact-checked, and revised the same way.
Claude Code, run in the desktop app, wrote every line. I directed in plain English — no code written by hand.
Geist typography, a two-register color system, dark mode, responsive layouts — not a bought theme.
Edit the inputs, watch the totals move, download a real .xlsx — built with no spreadsheet library at all.
Code lives on GitHub, deploys to Cloudflare, and answers at kaylo.co. The only paid pieces are the domain and the Claude subscription that built it.
| Layer | Tool | Cost |
|---|---|---|
| Built with | Claude (Claude Max plan) | $100 / mo |
| Code & version control | GitHub | Free |
| Hosting, CDN & HTTPS | Cloudflare Pages | Free |
| Domain — kaylo.co | Squarespace | ~$35 / yr |
Static files push to a GitHub repo; Cloudflare Pages deploys them to a global CDN with free HTTPS; kaylo.co is registered through Squarespace and points at Cloudflare. No server to run, nothing to patch.
The site itself costs about $35 a year to run. Hosting and version control are free. The only real expense is the Claude Max plan at $100/mo — and that’s not a website cost; it’s the tool I use for client work, the deliverables, and this. It replaced a $30/mo Squarespace website plan — $360 a year — that couldn’t have built the calculator, the library, or any of the interactive pieces.
This site is the AI-for-HR thesis, lived. I’m an HR person, not an engineer — and I built and shipped a real website with working tools for the cost of a domain and a Claude subscription. The workflows your HR team runs by hand are no harder than this was.
That’s the work I do: helping HR teams build with Claude.
