- Gecko This has a free Java applet but the full one is not free.
- Circuit Simulation Applet Not sure this has the full range of componets ie it doesn't have a IGBT, still it looks good
- 5Spice is a graphic design of circuits that you will have to buy after 30 days, I think However it is related to spice
- Spice this is a text based way of doing circuits, there is many application who have added graphical displays to run spice, normally this isn't for free.

I have been introduced to PLECS which can be used in MATLAB or stand alone application unfortunatley this is a paid application. So the freeware application I have seen so far are:
