  We analyse forward-jet production at HERA in the framework of the
Golec-Biernat and Wusthoff saturation models. We obtain a good description of
the forward jet cross sections measured by the H1 and ZEUS collaborations in
the two-hard-scale region kT ~ Q >> Lambda_QCD with two different
parametrisations with either significant or weak saturation effects. The weak
saturation parametrization gives a scale compatible with the one found for the
proton structure function F_2. We argue that Mueller-Navelet jets at the
Tevatron and the LHC could help distinguishing between both options.
