The development of Algol played an important role in establishing computer science as an academic discipline. The Algol 68 Genie project preserves Algol 68 out of educational as well as scientific-historical interest, by making available a recent checkout compiler-interpreter written from scratch by Marcel van der Veer.

Algol 68 Genie is free software distributed under the GNU General Public License . It supports complex analysis, linear algebra, arbitrary precision arithmetic and partial parametrisation. It can optionally be linked to GNU plotutils, the GNU scientific library or PostgreSQL.

The algol68g-2.3.9 distribution released in April 2012 lets you build Algol 68 Genie on Linux, FreeBSD, Mac OS X, Solaris or Cygwin from source code. Detailed installation instructions are in the book Learning Algol 68 Genie which comprises an informal introduction to the language, a manual for Algol 68 Genie, and the Revised Report on Algol 68.

For Microsoft Windows XP, Vista or Windows 7, an algol68g-2.3.8 WIN32 executable is available which is linked to GNU plotutils and the GNU scientific library. Unzip it and execute it from the Windows command line interpreter cmd.exe.

Prebuilt binaries have been posted for Linux, Mac OS X, Debian, Solaris, FreeBSD, Fedora, RedHat, Ubuntu and Arch Linux. An important repository is the Algol 68 project on SourceForge.
