I will review the bootstrap approach to AdS scattering amplitudes. I will mostly focus on the tree-level amplitudes of super gluons and explain how all massless and massive four-point amplitudes can be uniquely fixed using only symmetries and consistency conditions. I will show that these amplitudes enjoy many interesting properties. In particular, there is an AdS version of the flat space color-kinematic duality. I will also point out new structures with no flat space analogues, which include a curious dimensional reduction structure related to the Parisi-Sourlas supersymmetry. 


I will also briefly discuss the results of AdS super graviton amplitudes




which can be computed using the same techniques, and share many features with the gluons.
