Computer Vision Annotation Tool (CVAT)

Computer Vision Annotation Tool (CVAT) is a high-performance, web-based platform designed for the complex requirements of professional data annotation for computer vision models. Originally developed by Intel and now managed by CVAT.ai, the platform has evolved into a comprehensive data management suite in 2026, offering seamless support for 2D images, video interpolation, and 3D point cloud (Lidar) data. Its architecture is built around a robust Django backend and a React frontend, optimized for high-throughput labeling tasks. CVAT distinguishes itself through its tight integration with automated annotation tools like Segment Anything (SAM) and YOLO models via Nuclio, allowing teams to leverage AI-assisted pre-labeling. This reduces manual effort by up to 80% in high-density scenarios. In the 2026 market, CVAT maintains a dominant position as the bridge between open-source flexibility and enterprise-grade SaaS reliability, supporting diverse deployment models from local Docker containers to fully managed cloud environments. It remains a critical piece of the MLOps pipeline for industries ranging from autonomous driving to precision agriculture, providing granular quality control, role-based access, and deep versioning capabilities.
