NASM — The Netwide Assembler

This is the project webpage for the Netwide Assembler (NASM), an assembler for the x86 CPU architecture portable to nearly every modern platform, and with code generation for many platforms old and new.

Development Team

NASM was originally developed by Simon Tatham and Julian Hall, and is now maintained by a team led by H. Peter Anvin of Intel Corporation.

Currently active team members are:

H. Peter Anvin
Cyrill Gorcunov
Sheng Yongjie
Maciej Wieczor-Retman

... with support from many others, and we are always looking for more developers.

Moving more services to github

We will be moving more services to github in the near future. The github Issues are now open and preferred over bugzilla. The forums are intended to be replaced by github discussions and wiki when they are set up in the near future.

Bug reports

Please report bugs to our bug tracker. Unfortunately we are often unable to address things immediately, but we will look at them as soon as we can.
