Unisys manufactures ClearPath mainframes, based on earlier Sperry and Burroughs product lines.

In 2002, Hitachi co-developed the zSeries z800 with IBM to share expenses, but subsequently the two companies have not collaborated on new Hitachi models.

Hewlett-Packard sells its unique NonStop systems, which it acquired with Tandem Computers and which some analysts classify as mainframes.

Fujitsu (formerly Siemens) BS2000, and Fujitsu-ICL VME mainframes are still available in Europe.

Fujitsu, Hitachi, and NEC (the "JCMs") still maintain nominal mainframe hardware businesses in their home Japanese market, although they have been slow to introduce new hardware models in recent years.
