webKnossos is an open-source tool for exploring large 3D electron-microscopy (EM) and light-microscopy (LM) datasets as well as collaboratively generating annotations. The web-based tool is powered by a specialized data-delivery backend that stores large datasets efficiently on disk and serves many concurrent users. webKnossos has a GPU-accelerated viewer that includes tools for creating and sharing annotations (skeletons and volumes). Powerful user and task management features automatically distribute tasks to human annotators. There are a lot of productivity improvements to make the human part as efficient as possible. webKnossos is also a platform for showcasing datasets alongside a paper publication.
