MiniMagAsm is minimalistic, but powerful and flexible content management system (CMS). It is a rewrite of MiniMag in assembly language (FASM). As expected, it is a very small and very fast Web application. It has a flexible architecture and is highly customizable by the user without the need for the code to be changed and recompiled. The system uses .txt files to store articles, formatted with a lightweight markup language which is very similar to Markdown. MiniMagAsm is portable CGI application which runs on Windows or Linux Web hosting.
