One reason Knotfolio doesn't yet calculate signature is due to numerical stability concerns.

I'm sure there are some algorithms out there for rigorously computing signatures of integer matrices, but failing that there's a skein relation for the computation due to a theorem of Murasugi. This is explained in https://math.stackexchange.com/questions/3180121/reference-request-for-knots-signature-via-skein-relation
