Canopy is an open-source platform for FAIR-aligned scientific data hubs, supporting data sharing, harmonization, discovery, and reuse across research studies. Canopy is derived from the NIH RADx Data Hub (https://radxdatahub.nih.gov/), a cloud-based platform originally developed for the NIH Rapid Acceleration of Diagnostics (RADx) program. RADx Data Hub is available on GitHub. Rather than presenting a one-size-fits-all data hub, Canopy enables customization of RADx Data Hub technology for the needs of specific scientific domains.
Live demo: A demonstration instance of Canopy is publicly available at canopy.stanford.edu. All studies, datasets, and files on that site are synthetic and intended for demonstration purposes only.

Canopy runs on AWS as a microservices platform:
- 7 Spring Boot microservices on ECS Fargate, behind an Application Load Balancer
- Next.js / React frontend with server-side rendering
- PostgreSQL (RDS) for relational data persistence
- OpenSearch for full-text and faceted search
- AWS Lambda for asynchronous email processing and search reindexing
- S3 for dataset file storage
- Keycloak for authentication and authorization
- CloudFormation (IaC) for repeatable, auditable AWS deployments
