In the field of cross-platform virtualization, there have been many point products developed over the years that aimed to deliver a specific "Platform A to Platform B" solution. For example, there was the IA32 Execution Layer (EL) from Intel, which allowed x86 applications to run on Itanium processors, and Microsoft's Virtual PC for the Mac, which allowed Windows/x86 applications to run on older Apple Macintosh systems equipped with OS 9 and PowerPC processors. Both products have since been discontinued.

However, there are currently no other "anything-to-anything" cross-platform virtualization vendors aside from Transitive, which has developed products during the past decade that have supported the ARM, Itanium, MIPS, Power, SPARC and x86 architectures, among others. Transitive's QuickTransit features a unique three-tier design that makes it comparatively easy to create new cross-platform virtualization solutions, by either switching the back-end code generator to support a different host or by changing the front-end CPU instruction decoder to support applications compiled for a different platform.
