FreeRouting

Free push&shove router for printed circuit board designs. Communicates with host PCB design systems via the standard Specctra DSN interface.

In standard settings this software works with double-sided PCB design. For hobbyists and amateurs who mostly use only the bottom copper layer, this can be easily set. Choose 'parameter' in the menu bar and open the 'Autorouter' options. Check off the top layer.
