  We study chaos in non-Lorentzian field theories, specifically Galilean and
Carrollian conformal field theories in two dimensions. In a large central
charge limit, we find that the Lyapunov exponent saturates the bound on chaos,
conjectured originally for relativistic field theories. We recover the same
Lyapunov exponent holographically by a shock-wave calculation in
three-dimensional flat space cosmologies, providing further evidence for flat
space holography.
