A highly optimized, low-level web server, now dynamic with CGI support and Linux compatibility.
This project targets extreme performance and resource efficiency, a critical concern in specific infrastructure contexts, particularly edge computing or embedded systems where ARM64 is prevalent. The shift from macOS-only to Linux and the addition of CGI support significantly broaden its applicability, moving it from a niche curiosity to a potentially viable component for specialized, high-performance backend services. While not a general-purpose web server replacement, its assembly-level optimization addresses a pain point for applications demanding minimal overhead and maximum control. This demonstrates continued innovation in foundational infrastructure components, driven by specific performance and resource constraints.
This is ymawky, a now-dynamic web server written entirely in ARM64 Assembly. I've previously posted about ymawky here: https://news.ycombinator.com/item?id=48080587In the past month and a half, I've made some pretty major improvements: I've added CGI scripting support, so the server now supports query strings and dynamic content; and I've fully ported ymawky to run on Linux, rather than macOS-only.In addition to GET/PUT/HEAD/DELETE/OPTIONS requests, because of CGI support ymawky also accepts POST requests (only to CGI resources for now).I've also updated the more detailed writeup to reflect CGI support and the Linux port: https://imtomt.github.io/ymawky/

> written entirely by-hand in ARM64 assembly as a fun project. It's probably got a lot of vulnerabilities I'm unaware ofImpressive, but that second part worries me. I hope one day AI security scans upon commit (or integrated in the IDE) will alleviate that risk.What's the current security gold standard for web servers? Hiawatha? https://hiawatha.leisink.net/
Is an assembly webserver more performant than webservers written in other languages? Are there any hard limits on how much you can squeeze when using a particular framework?
arm64 is an IP-locked ISA, namely it is not worth assembly writting, stick to plain and simple C.RISC-V is. I am self-hosting many of my internet thingies. I plan to move to RISC-V only hardware and to rewrite my internet software directly in mono-threaded paranoid RISC-V assembly.
"raw syscalls only: no libc wrappers"insane! i wonder how many times you have spent to learn about them!
I love it :-)Back in the distant past I wrote some really big ARM 32 assembly projects. 64 bit ARM is really very similar!I had a look through the code. Some ENTRY/EXIT macros to help with the drudgery of save restore registers & stack frame would probably help. Also some register renaming would help readability (eg if a register points to incoming data throughout a subroutine rename it pdata).I salute your effort and please enjoy the core dumps :-)
I love projects like this because I think eventually all common computing tasks will be broken down in constituent most computationally optimized components
Ahh, this little gem ported to Linux, great! That opens much more possibilities to play with it, thanks
You wrote this by hand? Impressive.
Cool. I particularly like the O'Reilly book cover that never was. Although I fear you may have misunderstood what wasm is...Question/critique. Isn't getting the mime type by file extension a bit windowsy? Would it not be easier to read the magic number when you're at the assembly level?
This isn't a bad thing per se. I imagine this could be a thing for an embedded side project or a tiny rescue system.Edit: or learning arm64 assembly :)
