MyOpenLab is described as 'platform for finished elements (program components) that can be linked together. You can also MyOpenLab with a house builder compare the building blocks used to build his house. The modules often create others'. There are seven alternatives to MyOpenLab for Windows, Linux, Mac and MS-DOS. The best alternative is LabVIEW. It's not free, so if you're looking for a free alternative, you could try itom or Emulino. Other great apps like MyOpenLab are FlowStone (Paid), proteus VSM (Paid), Lawson Labs (Free) and Comedi (Free, Open Source).
