tingsvad.dk
40+ Cloudflare features. One fictional village.
The project
An open, working demonstration of the Cloudflare Developer Platform.
tingsvad.dk is open source, wrapped in a fictional local history of a Viking-age thing (assembly) at a river ford that has been adjourning the same case about a cow since the year 980. Behind the humour the site is a serious reference: every page is a real use of a Cloudflare feature, and the colophon explains what each part does.
Every page is also served as Markdown to AI agents (Accept: text/markdown), errors answer as RFC 9457 problem details, and an MCP server lets AI assistants use the thing.

Build your own
The engine behind this website.
wi24rd.com, the site you are reading, runs on tingsvad.dk’s engine: one Worker with static assets, shared navigation inserted with HTMLRewriter and no build step, Markdown for agents, security headers – and a machine room where the infrastructure is measured live. The engine is open source and free to take; wi24rd.com’s own content, design and code are private. The universe with the cow stayed home in Tingsvad.
The repository contains a guide and a start prompt for building your own site the same way, plus Claude skills for the setup.

The core runs on a free Cloudflare account; a few features (the daily audit with Browser Run, Web Search, higher AI volumes) need Workers Paid.
