Here we investigate WCFT2s using circuit complexity as a tool. First we compute the holographic volume complexity (CV) which displays a linear UV divergence structure, more akin to that of a local CFT2 and has a very complicated dependence on the Virasoro central charge c and the U(1) Kac-Moody level parameter k. Next we consider circuit complexity based on Virasoro-Kac-Moody symmetry gates where the complexity functional is the geometric (group) action on coadjoint orbits of the Virasoro-Kac-Moody group. We consider a special solution to extremization equations for which complexity scales linearly with "time". In the semiclassical limit (large c,k, while c/k remains finite and small) both the holographic volume complexity and circuit complexity scales with k.en-USWarped conformal field theoryVirasoro-Kac-Moodycircuit complexityHolographic volume complexityVirasoro central chargee-Printe-Print123456789/615
