Building Web & Apps
A hands-on guide to building and running your own websites and apps, in the order the work actually happens. We cover choosing a domain and a server, measuring how fast a page opens in different countries, getting found in search and adding ads, and the steps for publishing an app to the stores.
This is also home for small tool-style sites people use for a moment and leave - so-called low-involvement web and apps. We look at how to ship one feature quickly, how to bring visitors back, and which choices keep running costs down, with real examples. Trends in generative AI technology and industry live in "AI & Development"; here we stay with what you run into when you build and operate things yourself.
Things you can check with numbers, such as speed, search visibility and running costs, come with how to measure them and how to read the results, along with case notes on improving small tools step by step.
Site Speed by Country
See how fast your site responds from many countries at once. Each country shows DNS, connect, TLS and time to first byte, plus the response status.
Example: measure https://example.com from Korea, Japan and the US to see each country's time to first byte and which step is slow.
