A pure ARM64 Assembly web server, now on Linux with CGI for no reason

In plain words

Ymawky is a web server written entirely in ARM64 Assembly that runs on Linux. It handles standard HTTP requests including GET, PUT, HEAD, DELETE, and OPTIONS, and supports POST requests through CGI scripting for dynamic content and query strings. The server is built from low-level assembly code rather than higher-level programming languages, making it an unusual approach to web server development for developers interested in systems programming.

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 originally developed for MacOS, this branch is a fully-featured Linux port. To compile a stripped binary, run make . To compile a binary with debugging symbols, run make debug 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.

  Building a web server in assembly to give my life (a lack of) meaningMay 2026 · github.com · ▲430

  This is ymawky, a static file web server for MacOS written entirely in ARM64 assembly. It supports GET, PUT, DELETE, HEAD, and OPTIONS requests, and supports Range: bytes=X-Y headers (which allows scrubbing for video streaming). It decodes percent-encoded URLs, strictly enforces docroot, serves custom error pages for any HTTP error response, supports directory listing, and has (some) mitigations against slowloris-like attacks. I’ve also written a more detailed writeup here: https://imtomt.github.io/ymawky/

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
