We derive constraints from Lyman-$\\alpha$ forest observations for both cases, basing ourselves on a reinterpretation of the existing Lyman-$\\alpha$ limits on thermal warm DM. We exclude DM masses below 15 keV for freeze-in, in good agreement with previous literature, and provide a generic lower mass bound for superWIMPs that depends on the mother particle decay width.
