Our verdict on Prodigy
Prodigy is a downloadable, Python-based annotation tool for creating training and evaluation data for machine-learning systems. It is designed for developers, researchers, data-science teams, and enterprises working with image classification, bounding boxes, polygons, and image segments. Browser-based interfaces, custom Python recipes, model-assisted labeling, and human review support workflows where teams need control over annotation logic and data handling. It runs on user hardware and supports web, Windows, macOS, Linux, API, and self-hosted deployments.
Pricing is organized around lifetime licensing rather than a recurring subscription. The Personal plan costs $390 per lifetime license and includes 12 months of free upgrades, the installer, web application and plugins, basic HTTP authentication, community forum support, and unlimited personal and professional use. The Company plan costs $490 per seat and adds HTTP authentication with SSO through OpenID Connect, priority forum and email support, and seats transferable within the company. Both plans include a lifetime license, 12 months of free upgrades, the installer, web application, and plugins. The published plans show no free plan, so the cost structure suits teams that expect sustained use rather than casual evaluation.
Prodigy's strongest fit is a Python-centric machine-learning workflow that benefits from active learning, custom interfaces, annotation review, and direct data exchange. Its REST API includes interactive documentation, while JSON and JSONL import and export support downstream training workflows. Integrations with spaCy, Hugging Face, PyTorch, TensorFlow, and Jupyter connect annotation work to common machine-learning environments. Choose Prodigy when workflow control, on-premise or offline operation, and model-assisted labeling matter. Teams seeking a free entry tier, a primarily managed service, or broader built-in collaboration features should consider alternatives.
