  Umami is a simple, fast, privacy-focused alternative to Google Analytics.

  

For a while now, I've been creating mini web tools to test out ideas or as tiny helpers for myself. I usually publish them on individual subdomains, which might not be the best idea, but I like the concept of a short, easy-to-remember URL. Recently, I discovered that some of these tools actually have a few users, which made me consider adding analytics to them. After a bit of research, I settled on umami. It's a great little privacy-conscious tool with exactly what I need and nothing more.

  ⛅️ Home to Wrangler, the CLI for Cloudflare Workers®

  

Except that there is. Cloudflare is pretty great for free SSL certificates and DNS management, but they also offer a free Workers plan. A Cloudflare worker is basically JavaScript code that runs on Cloudflare's edge network and handles HTTP traffic. You can do a lot with workers, including modifying/rewriting HTML responses. You can probably see where this is going: If a worker can modify HTML responses, then it can inject the umami script into every HTML response.
