  We present a systematic study of holographic correlators in a vast array of
SCFTs with non-maximal superconformal symmetry. These theories include 4d
$\mathcal{N}=2$ SCFTs from D3-branes near F-theory singularities, 5d Seiberg
exceptional theories and 6d E-string theory, as well as 3d and 4d
phenomenological models with probe flavor branes. We consider current
multiplets and their generalizations with higher weights, dual to massless and
massive super gluons in the bulk. At leading order in the inverse central
charge expansion, connected four-point functions of these operators correspond
to tree-level gluon scattering amplitudes in AdS. We show that all such
tree-level four-point amplitudes in all these theories are fully fixed by
symmetries and consistency conditions and explicitly construct them. Our
results encode a wealth of SCFT data and exhibit various interesting emergent
structures. These include Parisi-Sourlas-like dimensional reductions, hidden
conformal symmetry and an AdS version of the color-kinematic duality.
