NASM (the Netwide Assembler) is a portable, cross-platform assembler for the x86 and x86-64 CPU architectures using Intel-like syntax. It supports many output formats and is licensed under the 2-clause BSD license.

Use cases

assemble x86 assembly code
write bootloaders or OS kernels in assembly
compile assembly for x86-64 with Intel syntax
generate object files in multiple formats like ELF or COFF
learn x86 assembly programming

When to choose

you need a mature, portable x86 assembler with Intel syntax
you target multiple output formats and platforms
you are writing low-level code such as bootloaders, kernels, or optimized routines

When to avoid

you prefer AT&T syntax (consider GNU as)
you need a high-level assembler with macros for other architectures like ARM
