We show that many interesting spaces — including all positroid strata and wild character varieties — are moduli of constructible sheaves on a surface with microsupport in a Legendrian link. We recover the cluster structures on these spaces from the Floer theory of Lagrangian fillings of these Legendrians. We also use results in cluster algebra to construct and distinguish exact Lagrangian fillings of Legendrian links in the standard contact three space.
