history

Project history and usage

NASM, the Netwide Assembler, is a long-running x86 and x86-64 assembler with Intel-like syntax, broad object-format support, a companion disassembler `ndisasm`, and a reputation as a standard tool for low-level x86 work.

Project history

The official NASM site says the project was originally developed by Simon Tatham and Julian Hall and is maintained by a team led by H. Peter Anvin. The documentation's version history records version 0.90 in October 1996 as the first release version and the first support for object-file output.

NASM 2.00 added general x86-64 support, Win64 COFF, ELF64, and Mach-O output formats. NASM 3 series became the production version in 2025 and added APX instruction encodings and preprocessor improvements. The official site listed stable version 3.02 on 2026-06-29 and a development snapshot dated 2026-07-01.

Adoption history

NASM is packaged almost everywhere: Homebrew input data lists Alpine, Debian, Fedora, MacPorts, Nix, pacman, Scoop, Ubuntu, winget, and zypper package names. Homebrew's formula JSON generated on 2026-07-01 reported 93,847 installs over 365 days and 35,027 installs-on-request over 365 days, making it the dominant package in this batch by Homebrew adoption.

GitHub API data fetched on 2026-07-01 showed 3,249 stars and 410 forks for the current GitHub-hosted repository. Those numbers understate its age because NASM predates GitHub by more than two decades and has long been distributed through project tarballs, OS packages, compiler-course notes, and low-level systems tutorials.

How it is used

Users assemble source with commands such as `nasm -f elf myfile.asm` for object files or `nasm -f bin program.asm -o program.com` for flat binaries. The package also installs `ndisasm`, useful for disassembling raw x86 byte streams.

Package nerds encounter NASM as a build dependency for projects containing hand-written x86 assembly, codec kernels, bootloaders, OS-dev experiments, exploit/reversing exercises, and compiler or architecture classes. Its value is the predictable Intel-like syntax and explicit output-format selection.

Why package nerds care

NASM is one of the canonical x86 assembler packages. It matters because it is small, scriptable, cross-platform, and stable enough to appear as a dependency in build systems that need exact x86 object generation without invoking a full compiler frontend.

Timeline

1996-10: NASM 0.90 released as the first release version with object-file output support.
2007: NASM 2.00 series added general x86-64 support and 64-bit object formats.
2025: NASM 3 series became the production line, adding APX instruction encodings.
2026-06-29: NASM 3.02 listed by the official site as stable.
2026-07-01: Homebrew formula JSON listed stable version 3.02 and 93,847 installs over 365 days.
