Build it yourself
Claude builds your website the way I build mine
The guide is a plugin for Claude. It holds everything I’ve learned building my own websites: rules, templates and more than 100 known pitfalls. You install it once. After that, Claude builds by my rules. The sites load quickly and mostly need no cookie banner.
How fast a site built with this guide turns out
This website is built with the guide. Measured with Lighthouse, home page, mobile, as of 15.10.2026.

Lighthouse measures in the lab with a simulated phone. Your site will score a little differently, depending on its content and images.
What’s in the plugin
The plugin consists of skills, agents and connectors. Claude loads them when the task calls for it.
5 skills
The main guide to building, plus measurement and dashboard, going live, checking a finished site, and the special route for Google Analytics with consent.
4 agents
Scout, Builder, Writer and Checker. The work is shared out so the most expensive model doesn’t have to do everything.
3 connectors
Cloudflare Bindings, Cloudflare Docs and Supabase. The first time you use them, you sign in with your own account.
25 templates
Code and text to reuse, for example for headers, forms, multiple languages and measurement.
More than 100 pitfalls
Mistakes I’ve made myself, with the fix. Claude knows them before it makes them.
What Claude keeps in mind while building
- A round of questions before building
- Design system and structure
- Speed
- Security and headers
- Privacy and legal texts as a draft
- Forms and email
- Multiple languages
- Search engines
- Supabase and booking
- Measurement without cookies
- Going live and moving a domain
What you need to bring
- A paid Claude subscription
- Accounts with Cloudflare, Supabase and GitHub
- A domain of your own
- A basic understanding of how a website works
Who it’s for
It suits you if
- you want to build your website yourself and have Claude do the work
- you build websites for clients and want a fixed way of working
- fast pages and privacy matter to you
Probably not if
- you don’t feel like dealing with accounts and settings
- you want a finished website without doing anything yourself: my packages are for that
- you’d rather use a site builder such as Wix or WordPress
Try it first
There is a free version of the guide: the “webseite-pruefen” skill with the list of known pitfalls. Claude uses it to check a finished site, or someone else’s, and gives you a list of improvements in order of importance. You don’t need to sign up.
You may pass the free version on unchanged and with credit to the source.

What the licence allows
You may
- use the plugin for your own websites
- use it for your clients’ websites, including paid work
- adapt it to the way you work
You may not
- pass on, publish or sell the files
- include them in your own course, template or plugin
The websites you build with the plugin belong to you and your clients without restriction. Every copy carries your licence number. The licence text is a draft and still has to be checked by a lawyer.
Updates and version 2
You get all 1.x versions at no extra cost. You download a new version with your licence number and the email address you bought with. If a version 2 comes later, you get it at a reduced price.
If you hire me later after all
If you book one of my packages later, I’ll credit the €149. Just send me your licence number. The credit applies to my work on text and structure, not to technology and running costs.
Questions about buying
What exactly do I get?
A file ending in .plugin. It contains the skills, agents and templates for Claude and a licence file with your number. You open it in Claude and install it.
Do I need to know how to code?
No. But you should roughly know what a domain, a Cloudflare account and a GitHub project are. Claude takes you through the steps, and you make the decisions.
What does it cost in total?
The plugin costs €149, once. On top of that comes your Claude subscription. Cloudflare, Supabase and GitHub have free plans for small websites. The domain costs a few euros a year.
May I use it for clients?
Yes. You may build as many websites for others as you like. You just may not pass on or resell the plugin’s files.
How do I get it?
After payment, the checkout sends you to a page with your licence number and the download. Stripe emails the receipt to you. If you lose the file, you download it again with your licence number and email address.
Can I return it?
The right of withdrawal follows the terms that Stripe’s checkout shows you before you pay. If there’s a problem, write to me and I’ll find a solution.
Is the plugin still being developed?
Yes. I use it myself on every project and add new experience and pitfalls. All 1.x versions are included in the price.
