We present an off-shell formulation of higher spin gravity, akin to topological open string field theory, in which the basic fields are differential forms of even and odd degrees valued in odd and even sectors of a Frobenius higher spin algebra. Locally, the model propagates the same degrees of freedom as Vasiliev's original higher spin gravity. The Frobenius extension enhances the gauge symmetry, leading to fewer invarants, hence a more predictable theory. It also turns the constant two-form into a dynamical field, whose vacuum expectation values may deform the internal noncummatative geometry.
