The masses of exotic nuclei near the limits of stability play an important role in a wide variety of studies, such as simulations of r-process nucleosynthesis occurring in supernovae, determination of reaction cross sections of halo nuclei, and global models of the structure of nuclei. To handle this amount of mass information, we have built an online, dedicated suite of codes. Our system, freely available at nuclearmasses.org, is a platform-independent client-server application. With our system, researchers can upload their own mass datasets, store them, share them with colleagues, and quickly and easily visualize them in customizable one- and two-dimensional plots. Mass dataset analysis tools are also available, enabling the average RMS differences between a reference dataset and numerous other sets to be determined. We have recently added the capability to visualize the two-neutron separation energy surface. More analysis tools will be developed for our suite.
