Developed originally for the U.S. Department of Defense, it is widely used in aerospace, defense, avionics, and embedded systems. AdaCore provides the primary commercial toolchain (GNAT Pro) along with static and dynamic analysis suites.

Unison Content-addressed functional language where code is stored as a hash-identified AST, enabling novel approaches to versioning and distribution.
