data.all vs Opendatabay

data.all is an open-source platform for managing and discovering data assets in AWS accounts. Its central catalog inventories datasets, tables, folders, and dashboards, with filters for asset type, tags, region, and glossary terms. Datasets can contain structured tables or unstructured folders and use AWS S3, KMS, IAM, and Glue resources. Teams can share datasets between environments by granting selected roles read access through Lake Formation without moving data. The catalog imports tables from Redshift Serverless and provisioned clusters. Analytics options include Athena worksheets, SageMaker Studio access, Jupyter notebooks, and QuickSight dashboards. Administrators manage teams and users across environments. Authentication supports Cognito federation with a corporate identity provider or an external OIDC provider. Deployments may face the internet or remain inside a VPC. AWS setup requires at least two matching-region accounts and administrator credentials.

Opendatabay is a marketplace for buying and selling datasets intended for AI and large language model use. Its listings span text, image, audio, video, code, agentic trajectories, 3D spatial, tabular, time-series, human feedback, and synthetic data. The documentation describes AI-powered search and recommendations, and says datasets are curated and labelled for model training or fine-tuning, with a claimed 20–40% reduction in preprocessing time. Buyers receive licensing terms and provenance information; the company says sellers undergo verification and due diligence. Both free and paid data products are offered, with provider-set prices for paid items. Sellers can list for free, while self-serve sales incur commissions ranging from 30% on sales of $1–$100 to 5% on sales of $250,001 and above. Registered users who complete onboarding can download evaluation samples, but production, commercial use, model training, and redistribution require a separate license or purchase agreement. The service is available on web and through an API. Only registered businesses, legal entities, or institutions may register as providers, and proof of business identity may be required.
