FluidLab is the new RBDLab Studio add-on.

FluidLab is a powerful tool for generating realistic simulations of fluids, viscous bodies, slimes and other fluids. You don't need a "Domain", you can create your simulations in real time in viewport, no need to wait for an "invisible" bake. You can interact different emitters with different densities, viscosities or behaviors.
