  We introduce HexaLab: a WebGL application for real time visualization,
exploration and assessment of hexahedral meshes. HexaLab can be used by simply
opening www.hexalab.net. Our visualization tool targets both users and
scholars. Practitioners who employ hexmeshes for Finite Element Analysis, can
readily check mesh quality and assess its usability for simulation. Researchers
involved in mesh generation may use HexaLab to perform a detailed analysis of
the mesh structure, isolating weak points and testing new solutions to improve
on the state of the art and generate high quality images. To this end, we
support a wide variety of visualization and volume inspection tools. Our system
offers also immediate access to a repository containing all the publicly
available meshes produced with the most recent techniques for hexmesh
generation. We believe HexaLab, providing a common tool for visualizing,
assessing and distributing results, will push forward the recent strive for
replicability in our scientific community.
