Using holographic subregion complexity, we study the confinement-deconfinement phase transition of a QCD-like gauge theory, holographically. In the model we consider here, we observe a connection between the potential energy of a probe meson and the behavior of its complexity. Moreover, near the critical point, at which the phase transition takes place, our numerical calculations indicate that we need less information to specify a meson in the nonconformal vacuum than in the conformal one, despite the fact that the nonconformal vacuum has larger energy.
