Ich habe einen echten Speedtest in Vanilla JS gebaut (mit Cloudflare API)

The article describes a simple speed test built with Vanilla JS and the Cloudflare API. The test measures internet speed without requiring a large node_modules directory or external libraries. It's a more transparent and controlled alternative to commercial speed tests. The test measures ping, download, and upload speeds using the Cloudflare API, and can be used to evaluate internet speed against a user's tariff.
