  We grow the web of dualities for conformal field theories (CFTs) in 2+1
spacetime dimensions to include quantum critical transitions of Dirac fermions.
Our construction uses the seed duality, equating a free Dirac fermion with a
complex boson coupled to a Chern-Simons gauge field, to express various
Gross-Neveu-Yukawa (GNY) critical points of N fermions in terms of the same
number of complex bosons and partner gauge fields. In some instances, monopole
operators appear explicitly in the dual action, such as for the superconducting
transition of a single Dirac fermion, which is a CFT with emergent
supersymmetry. We match phase diagrams, symmetries and their anomalies. By
further gauging certain symmetries, we derive offspring dualities. For example,
starting with the duality for the regular GNY transition of 2 Dirac fermions,
we arrive at the duality between a Neel-to-VBS deconfined quantum critical
point and a gauged-Gross-Neveu transition. Finally, we use a large-N expansion
for monopole operators, and compare with known scaling dimensions in the
simplest single-flavour GNY transition.
