You have accessed a server running on a $25 Walmart phone. This unit is currently sitting on my desk, serving web content to the global network.
VIEW UNIT SPECIFICATIONS → BUILD YOUR OWN →This $25 phone runs Termux (a Linux terminal for Android) with Andronix providing a full Ubuntu environment. nginx serves the static content, and Cloudflare Tunnel securely exposes it to the internet without opening any ports on my network.
I like building with constraints. A $25 phone running a full Linux server and serving pages to the world? That's just a fun project. Sometimes the best way to learn is to see how far you can push cheap hardware.
