CVAT vs Ultralytics Platform

CVAT turns images, video, 3D data and audio into labeled datasets for AI workflows. Its annotation tools include boxes, masks, polygons, keypoints, skeletons and object tracks, with additional listed types such as cuboids, ellipses and tags. Teams can review jobs through validation and acceptance stages and assess quality using ground truth, honeypots and consensus workflows. Storage connections include Amazon S3, Azure Blob Storage, Google Cloud Storage, compatible buckets and self-hosted storage. CVAT names SAM 2, SAM 3, Ultralytics, Hugging Face and custom models as labeling aids. It exports to more than 20 formats, including COCO, YOLO, KITTI, Cityscapes and Pascal VOC, and offers API, SDK and CLI automation. Deployment can be managed in the cloud or self-hosted, including on-premises and air-gapped options. Free plans are available; online paid plans start at $23/user/mo billed annually. CVAT lists security controls but says it does not hold ISO 27001 or SOC 2 certifications.

Ultralytics Platform brings dataset annotation, management, analytics, model training, export and deployment into one workspace. It supports detection, instance and semantic segmentation, classification, pose estimation and oriented object detection. Smart annotation creates masks and bounding boxes, and YOLO Smart annotation is included in Free. Users can import YOLO and COCO datasets and export annotations in Ultralytics NDJSON format. Analytics show class distributions, split imbalances, annotation heatmaps and image dimensions; users can also select a YOLO model and GPU to start cloud training. The Free plan costs nothing and includes 100 GB storage, 10 GB per upload, 100 models, three concurrent cloud training jobs, three deployments and community support. Pro costs $29 a month, billed per seat/month, and includes 500 GB storage, 20 GB per upload, 500 models, ten concurrent training jobs and deployments, up to five team members and priority support. Enterprise pricing is custom. Data residency options cover the EU, US and APAC. Ultralytics states that all plans include ISO/IEC 27001:2022 certification and SOC 2 Type I auditing.
