  The relationship between $T\bar{T}$ deformations and the uniform light-cone
gauge, first noted in arXiv:1804.01998, provides a powerful generating
technique for deformed models. We recall this construction, distinguishing
between changes of the gauge frame, which do not affect the theory, and genuine
deformations. We investigate the geometric interpretation of the latter and
argue that they affect the global features of the geometry before gauge fixing.
Exploiting a formal relation between uniform light-cone gauge and static gauge
in a T-dual frame, we interpret such a change as a TsT transformation involving
the two light-cone coordinates. In the static-gauge picture, the $T\bar{T}$ CDD
factor then has a natural interpretation as a Drinfel'd-Reshetikhin twist of
the worldsheet S matrix. To illustrate these ideas, we find the geometries
yielding a $T\bar{T}$ deformation of the worldsheet S matrix of pp-wave and
Lin-Lunin-Maldacena backgrounds.
