I will review the recent revival of S-matrix bootstrap in the context of massless EFTs. We will begin with the EFT of massless scalars, spinning and colored states and identify the data which we can hope to constrain. We will lay out the constraints of unitarity and locality in the UV and how it can be utilized to bound the low energy couplings through dispersion relations. We will focus in particular on gravitation systems, where the presence of massless poles requires a modern update to the bootstrap methods are required.
