CVAT (Computer Vision Annotation Tool) is an open-source, self-hosted platform for annotating images, videos, and 3D point clouds to build high-quality training datasets for computer vision AI. It supports bounding boxes, polygons, masks, skeletons, and tracks, with AI-assisted labeling, team collaboration, quality assurance workflows, cloud storage integration, and developer SDKs/APIs.

Use cases

  • annotate images with bounding boxes for object detection training
  • label video frames with object tracking
  • create semantic segmentation masks for datasets
  • annotate 3D point clouds from lidar
  • run AI-assisted auto-labeling with SAM or custom models
  • manage a team of annotators with review and QA workflows
  • self-host a data labeling platform with full data control
  • export annotations in formats like COCO, YOLO, or Pascal VOC

When to choose

  • you need a battle-tested, widely adopted annotation tool for computer vision datasets
  • you must keep sensitive visual data on your own infrastructure
  • you need multi-user collaboration, roles, and review pipelines for labeling teams
  • you want to plug in your own ML models to accelerate labeling
  • you need image, video, and 3D point cloud annotation in one platform

When to avoid

  • you only need simple text or tabular data labeling rather than visual data
  • you want a lightweight single-user desktop annotation tool without server deployment
  • you need audio annotation, which is not yet supported
  • you cannot operate Docker-based multi-service deployments
