My alignment gauge is the one that came with my Campagnolo toolchest, but I think there are better ones available. Velonews tested various alignment gauges some years ago: https://velo.outsideonline.com/road/road-racing/the-best-derailleur-hanger-alignment-tool-9-tested/ .
It's also quite possible to make your own. Google "home made derailleur alignment gauge" (without the quotes) and you'll got lots of hits. Another option is to use a spare steel rear axle, as most cup and cone rear hub steel axles use the same M10 x 1.0 thread size and pitch as the hanger (the exception being Campagnolo axles). You can thread a spare axle into the dropout from the inside and compare it's parallelism in different planes with another axle sitting in the dropouts.
