Gravity is generally agreed to be a "force" but not in the classical sense. We are not yet aware of any "mediator" of the force like in most other forces (eg the photon mediating the electromagnetic force etc.) and it is probably a spacetime curvature. But it is still very common to refer to it as a force. Just look at pretty much every legitimate physics website and they will freely use the term "force".
It's perfectly reasonable to call gravity a "force" but recognize that may not be like the other fundamental forces. There's a reason F=Gmm/r^2 starts with an "F".
