Building a Web Server in Raw ARM64 Assembly: Because C Was Too High-Level

Remember that feeling when you write console.log and know magic happens under the hood? One brave soul decided to peek under the deepest hood and wrote a web server in raw ARM64 assembly. No libc, no OS, just registers and syscalls.

It's like assembling IKEA furniture without instructions or a screwdriver — except instead of screws you have bytes, and instead of a wrench you have a debugger. The project shows how to handle HTTP requests at the lowest level: open a socket, accept a connection, read data, send a response. Spoiler: the code is not production-ready, but educational — it's fire.

Of course, for production such a server is useless (unless you want your deployment to turn into a survival quest), but for understanding what actually happens with every curl localhost:8080, it's priceless. Especially when you realize how much work modern frameworks do for us, while we complain about an extra 10 milliseconds.

In short, if you're tired of yet another JS framework breaking your CI and want to remember what it's like to control every bit, welcome to assembly land. At least there you know why everything broke: because you forgot to save a register.

METABYTE studio comment: We're not suggesting you write production servers in assembly, but understanding low-level magic helps even in high-level projects. And if your server does crash — we'll help you bring it back faster than you can say "segmentation fault".
