Yes, they have Mac, Linux and Windows version of the software. Closed source but free from Saleae. The $8 clone is just a tiny uP that reads 8 input pins really fast and puts the data on USB. Al the smarts is in the software.
Saleae makes some really nice ones that use the same software but have more pins and faster pins and can handle more different voltage levels. One thing that modern logic analyzers can do that scope can't is trigger on data. Sigrok looks good but I don't use it much, just checked it out a little. The Saleae software is so easy to use you don't need a user manual.
