data.all vs Data Marketplace

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.

Data Marketplace is a service for finding, evaluating, buying, and selling machine-ready datasets. Analysts can use its dashboard, while AI agents can use an API, REST endpoints, a hosted MCP server, or an OpenAPI specification to discover, query, and purchase data. Each dataset listing includes a machine-readable schema, data dictionary, and automated PII detection report. Buyers can preview 50 rows and filter by format, license, recency, and quality score. Uploads are scored for completeness, freshness, and consistency; after payment clears, purchased datasets can be downloaded as CSV, Parquet, or JSON. Buyers can post data requests with a reward, and providers can compete to fulfill them; payment is due only if the result meets the stated specification. Datasets are scanned for personal information before publication, but uploaders are responsible for having a lawful basis to share personal data. The terms call the service an early-access beta, with features that may change or be removed and no guarantee that data will be retained. The free plan costs nothing; Starter costs $19 a month.
