It is used by tens of thousands of users and companies around the world. Our mission is to help developers, companies, and organizations around the world to solve real problems using the Data-centric AI approach. Start using CVAT online: cvat.ai. You can use it for free, or subscribe to get unlimited data, organizations, autoannotations, and Roboflow and HuggingFace integration. Or set CVAT up as a self-hosted solution: Self-hosted Installation Guide. We provide Enterprise support for self-hosted installations with premium features: SSO, LDAP, Roboflow and HuggingFace integrations, and advanced analytics (coming soon). We also do trainings and a dedicated support with 24 hour SLA. Quick start ⚡ • Installation guide • Manual • Contributing • Datumaro dataset framework • Server API • Python SDK • Command line tool • XML annotation format • AWS Deployment Guide • Frequently asked questions • Where to ask questions Partners ❤️ CVAT is used by teams all over the world. In the list, you can find key companies which help us support the product or an essential part of our ecosystem. If you use us, please drop us a line at contact@cvat.ai. • Human Protocol uses CVAT as a way of adding annotation service to the Human Protocol. • FiftyOne is an open-source dataset curation and model analysis tool for visualizing, exploring, and improving computer vision datasets and models that are tightly integrated with CVAT for annotation and label refinement. Public datasets ATLANTIS, an open-source dataset for semantic segmentation of waterbody images, developed by iWERS group in the Department of Civil and Environmental Engineering at the University of South Carolina is using CVAT. For developing a semantic segmentation dataset using CVAT, see: • ATLANTIS published article • ATLANTIS Development Kit • ATLANTIS annotation tutorial videos. CVAT online: cvat.ai This is an online version of CVAT. It's free, efficient, and easy to use. cvat.ai runs the latest version of the tool. You can create up to 10 tasks there and upload up to 500Mb of data to annotate. It will only be visible to you or the people you assign to it. For now, it does not have analytics features like management and monitoring the data annotation team. It also does not allow exporting images, just the annotations. We plan to enhance cvat.ai with new powerful features. Stay tuned! Prebuilt Docker images 🐳 Prebuilt docker images are the easiest way to start using CVAT locally. They are available on Docker Hub: • cvat/server • cvat/ui The images have been downloaded more than 1M times so far. Screencasts 🎦 Here are some screencasts showing how to use CVAT. Computer Vision Annotation Course: we introduce our course series designed to help you annotate data faster and better using CVAT. This course is about CVAT deployment and integrations, it includes presentations and covers the following topics: • **Speeding up your data annotation process: introduction to CVAT and Datumaro**. What problems do CVAT and Datumaro solve, and how they can speed up your model training process. Some resources you can use to learn more about how to use them. • **Deployment and use CVAT**. Use the app online at app.cvat.ai. A local deployment. A containerized local deployment with Docker Compose (for regular use), and a local cluster deployment with Kubernetes (for enterprise users). A 2-minute tour of the interface, a breakdown of CVAT’s internals, and a demonstration of how to deploy CVAT using Docker Compose. Product tour: in this course, we show how to use CVAT, and help to get familiar with CVAT functionality and interfaces. This course does not cover integrations and is dedicated solely to CVAT. It covers the following topics: • **Pipeline**. In this video, we show how to use app.cvat.ai: how to sign up, upload your data, annotate it, and download it. For feedback, please see Contact us API • Documentation SDK • Install with • PyPI package homepage • Documentation CLI • Install with • PyPI package homepage • Documentation Supported annotation formats CVAT supports multiple annotation formats. You can select the format after clicking the **Upload annotation** and **Dump annotation** buttons. Datumaro dataset framework allows additional dataset transformations with its command line tool and Python library. For more information about the supported formats, see: Annotation Formats. | Annotation format | Import | Export | | ------------------------------------------------------------------------------------------------ | ------ | ------ | | CVAT for images | ✔️ | ✔️ | | CVAT for a video | ✔️ | ✔️ | | Datumaro | ✔️ | ✔️ | | PASCAL VOC | ✔️ | ✔️ | | Segmentation masks from PASCAL VOC | ✔️ | ✔️ | | YOLO | ✔️ | ✔️ | | MS COCO Object Detection | ✔️ | ✔️ | | MS COCO Keypoints Detection | ✔️ | ✔️ | | MOT | ✔️ | ✔️ | | MOTS PNG | ✔️ | ✔️ | | LabelMe 3.0 | ✔️ | ✔️ | | ImageNet | ✔️ | ✔️ | | CamVid | ✔️ | ✔️ | | WIDER Face | ✔️ | ✔️ | | VGGFace2 | ✔️ | ✔️ | | Market-1501 | ✔️ | ✔️ | | ICDAR13/15 | ✔️ | ✔️ | | Open Images V6 | ✔️ | ✔️ | | Cityscapes | ✔️ | ✔️ | | KITTI | ✔️ | ✔️ | | Kitti Raw Format | ✔️ | ✔️ | | LFW | ✔️ | ✔️ | | Supervisely Point Cloud Format | ✔️ | ✔️ | | Ultralytics YOLO Detection | ✔️ | ✔️ | | Ultralytics YOLO Oriented Bounding Boxes | ✔️ | ✔️ | | Ultralytics YOLO Segmentation | ✔️ | ✔️ | | Ultralytics YOLO Pose | ✔️ | ✔️ | | Ultralytics YOLO Classification | ✔️ | ✔️ | Deep learning serverless functions for automatic labeling CVAT supports automatic labeling.
