This is ymawky (yuh maw kee), a web server written entirely in ARM64 assembly. ymawky is a syscall-only, no libc, fork-per-connection web server written by hand. While it is developed for MacOS, I've tried to make it as portable as possible -- however , it's likely you will still need to make some (hopefully minor) Significant tweaks to get this to run on Linux/other Unix systems. See Implementation Notes for more details. Building Requires Xcode Command Line Tools. Install with xcode-select --install . ymawky only runs on apple silicon (arm64). Run make to build. Ensure there is a www/ directory next to the ymawky executable. That's the document root where ymawky searches for files. GET with an empty filename ( GET / ) will search for www/index.html , so you might want to make sure there's an index.html as well. ymawky will try to serve static error pages when a client's request results in error, eg 404.
