Could you build this?
No Writing a ~2KB standalone ELF binary that performs HTTP downloads without libc requires assembly or raw Linux syscall mastery and binary golf expertise.
What it would actually take: Must be built in raw assembly or freestanding C using raw Linux kernel syscalls (sys_socket, sys_connect, sys_write, sys_read, sys_open). It requires implementing raw TCP socket handling, HTTP/1.0 parsing, and custom ELF header manipulation to strip all bloat and overhead down to ~2KB. This requires deep systems programming, OS architecture, and binary reverse-engineering expertise.
Discussion
6 comments analyzed.
Competitors mentioned: libcurl, curl, HTTP proxy, kurl (DNS+TLS implementation)
Concerns raised: TLS implementation is unprotected/insecure, No new functionality compared to existing tools, Many servers require TLS-only support, Unclear advantage over established alternatives
Feature requests: DNS support, TLS with proper security

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
