Allegro CL 10.1 Free Express Edition Downloads

For commercial support or to evaluate the SMP version of Allegro Common Lisp please email, or call us at +1(510) 452-2000, ext. 300.

macOS Catalina (10.15) Users take note!

Catalina dropped support for 32-bit applications, and because Express is 32-bit it does not work on Catalina. Contact us if you would like to evaluate 64-bit Professional.

64-bit Ubuntu 13 (or later) Users take note!

Special steps are required for the Allegro CL Free Express Edition to work on 64-bit Ubuntu 13 and later because the Allegro CL Free Express Edition is a 32-bit application. See the documentation for details.



I agree to the Allegro CL Free Express Edition license agreement.
