Blitzbasic goes open-source

October 20, 2014 Leave a comment Go to comments

It’s probably old news to some, but I just noticed that BlitzPlus and Monkey X, two commercial grade compiler systems from Mark Sibly and Blitz Research, was committed into open-source over at github.

Blitzbasic comes in many versions, both 2D and 3D

Blitzbasic comes in many variations

Blitzbasic produces extremely fast code, tiny executables – and have been knocking out commercial games since the early 90’s. It was completely re-written for the PC some years back, is well maintained and up to date, and was in my view worth it’s initial $99 pricetag. So getting access to the underlying compiler and RTL source for free is a fantastic opportunity to learn from a master.

About BlitzBasic

BlitzBasic was initially released for the 16 bit Amiga home computer, following the great success of an older Basic interpreter “Amos Basic”, written by Francois Lionet. Unlike Amos Basic, Blitzbasic featured (and still do for x86) inline-assembler and was a real compiler system. Blitzbasic was responsible for successful games such as Worms and Hardball. Worms is still selling on mobile and console platforms to this day – and is one of the best selling games in computer history.

Worms was created in BlitzBasic, its one of the best selling games of all time

But Mark Sibly did not stop there. With the death of the Amiga platform he completely re-wrote the entire codebase in C++ for Windows, and have over the years maintained and made a living from his language. Blitzbasic is no “light weight” basic lingo, but by far the most advanced basic dialect out there. It features inline machine-code, templates, classes and much, much more.

Monkey X

Mark’s latest language, called “Monkey X” takes the whole Blitzbasic philosophy one step further. Monkey X is platform independent and generates code for XBOX, Playstation, Windows, iOS and OS X. You can also compile for HTML5 which is a great bonus for game and multimedia developers.

Mark has also decided to open-source Monkey X as well. From what the blog rumors say, Mark has worked to much for to long and wanted a clean break from computing – resulting in open sourcing his whole portfolio. I sincerely wish Mark the very best and that his health improves, he has been an inspiration to a whole generation of programmers and was one of the people that inspired me to become a programmer in my teens.

Blitzbasic and Monkey X are great products, both represents the most advanced basic dialects (although Monkey is C/JavaScript like in syntax) on the market. You are not limited to games only but can use Blitz and Monkey to generate serious platform independent software that runs native. Monkey uses transcoding, much like smart mobile studio, but targets C++, C#, Flash and other languages.


If you have even the slightest interest in compilers or how to make your own programming language, or indeed need a good platform to realize your game – then this should be considered winning the jackpot.

    Hi Jon,
    I have been using BlitzPlus for many years and would like to use the open source code to continue and maybe making some add-ons. Do you know if there is a commented version available. (Mark’s file have almost no comments.)
    Best regards, Philipp
