CVAT

What is CVAT?

CVAT is a data annotation platform for building computer vision and audio datasets. Annotators label images, video, 3D point clouds and audio with rectangles, polygons, polylines, ellipses and tracks that follow an object across frames, and reviewers check the results in a dedicated review mode. Quality tools include ground truth jobs, honeypots, consensus-based annotation and quality reports. Automation covers AI Tools, SAM 2 and SAM 3 segmentation, and models from Hugging Face and Roboflow. CVAT comes in three editions: the free Community edition you host yourself, the hosted CVAT Online with Free, Solo and Team tiers, and CVAT Enterprise for private cloud or on-premises use with SSO, LDAP, audit logs and support. A REST API, Python SDK and CLI let teams automate workflows, and expert labeling services are offered too. CVAT Online pricing runs $33 per month on monthly billing or $23 per month on yearly billing for Solo and per user for Team.

Use cases

• Label images for object detection
• Annotate video with object tracks
• Label 3D point clouds

Why use CVAT

• One tool covers image, video, audio and 3D labeling, so teams do not juggle separate annotation apps.
• Built-in quality control lets you measure annotator accuracy instead of trusting every label.
• You can start on the free hosted tier or self-host the Community edition at no license cost.
• Auto-annotation and SAM-based tools cut manual drawing work on large datasets.
• Enterprise deployment keeps data inside your own infrastructure for regulated environments.
