  We introduce SurfFlow, an open-source high-throughput workflow package
designed for automated first-principles calculations of surface energies in
arbitrary crystals. Our package offers a comprehensive solution capable of
handling multi-element crystals, nonstoichiometric compositions, and asymmetric
slabs, for all potential terminations. To streamline the computational process,
SurfFlow employs an efficient pre-screening method that discards surfaces with
suspected high surface energy before conducting resource-intensive density
functional theory computations. The results generated are seamlessly compiled
into an optimade-compliant database, ensuring easy access and compatibility.
Additionally, a user-friendly web interface facilitates workflow submission and
management, provides result visualization, and enables the examination of Wulff
shapes. SurfFlow represents a valuable tool for researchers looking to explore
surface energies and their implications in a diverse range of systems.
