CVAT

CVAT supports the widest variety of computer vision annotation tasks of any tool we have used or evaluated in the years I have worked in computer vision - classification, tracking, object detection, pose, attributes, and more! Gone are the days where we need to design our own labeling tool in-house to support a critical labeling feature. CVAT has multiple deployment paradigms which allow: working on locally in a development environment, deploying for a small team, or even deploying to a large team. It has a large, vibrant, active, responsive, and open community. The project's documentation is extensive and helpful for developers and annotators alike.
