The asymmetric unit of the title compound, C14H10FN3OS2, contains two independent mol­ecules which differ in the relative orientations of the triazole and allyl­sulfanyl groups with respect to the planar thio­chromen-4-one frameworks. The N—N—C—C torsion angles are 128.2 (5) and −120.9 (5)°, while the C—S—C—S torsion angles are −17.4 (4) and 16.4 (4)°. In the crystal, inter­molecular C—H⋯O and C—H⋯N hydrogen bonds link the mol­ecules in a stacked arrangement along the a axis.
