Keylabs review
Advanced annotation, QA, automation, and exports with usage-based hourly pricing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Keylabs is a data annotation platform for AI teams working with image, video, and 3D data. It combines manual labeling with model-assisted annotation, quality assurance, dataset management, and export tools. Teams can annotate bounding boxes, polygons, polylines, keypoints, segmentation, cuboids, meshes, bitmasks, and point clouds. Its role-based workflows and collaboration features make it suited to projects that need structured review rather than basic image marking.
Pricing is usage-based rather than per-user monthly pricing. The Startup plan costs $1 per hour and is designed for startups, individuals, or academies, with up to 10 non-admin users and 10 GB of storage. Business costs $2.3 per hour for growing businesses, supporting up to 50 non-admin users and 250 GB of storage. Pro costs $2.1 per hour for professional teams, with up to 300 non-admin users and 2 TB of storage. Enterprise is intended for ultimate teams and includes 50,000+ hours, unlimited users, and unlimited storage. This structure suits teams that can align spending with annotation activity.
The platform’s strongest differentiator is breadth. Model-assisted labeling can use pre-trained or custom machine-learning models, while automatic segmentation, video object tracking, multi-layer quality assurance, and annotator verification support larger or more complex datasets. Keylabs also connects to S3, Google Cloud Storage, and Azure, provides CLI and SDK tooling, and exports to Keylabs ZIP/JSON/PNG, COCO, and YOLO formats. Web and self-hosted deployment options, including on-premise deployment, broaden its fit for teams with infrastructure requirements. Choose Keylabs for advanced computer-vision workflows and programmatic integration; teams needing only occasional, simple labeling may prefer a narrower tool.
