It is believed that gravity is holographic, namely that the gravitational dynamics in a given spacetime (region) can be encoded by a nongravitational theory living on the boundary of that region. The AdS/CFT correspondence is an extremely successful concrete realization of the holographic idea; however, generalizing the holographic dictionary beyond AdS/CFT has proven to be difficult. My work focuses on the  rather general  instances of nonAdS holography where the boundary theory can be argued to correspond to a finelytuned finite irrelevant deformation of a conformal field theory (CFT). In this context, I will discuss the properties of two exactly solvable irrelevant deformations of twodimensional CFTs known as $T\bar T$ and $J\bar T$  deformed CFTs and the lessons they teach us about nonAdS holography.
