| Free tier | No clear public storage cap found. Platform is free SaaS on S3; documented pain point is a '1GB per day' quota on modelState (compute artifacts), not on file storage. unit mixed; metered on stored-bytes |
|---|---|
| Price | none stated |
| Limits | per-object-cap: none documented for plain files; 1 GB/day on modelState. Retention: indefinite for public content. Gate: upload requires 'certified user' status (a quiz), so no anonymous write path exists. |
| Identity | anonymous (inferred, not read) not published |
| Egress | Free to download for public projects; anonymous download of public entities is supported. |
| Per-object cap | not stated |
| Retention | per-object-cap: none documented for plain files; 1 GB/day on modelState. Retention: indefinite for public content |
| Interface | s3, rest, oci rest |
| Tooling | Python/Java/R clients (synapseclient), REST API, and a built-in Docker registry. Also supports custom storage locations (your own S3/GCS) — which makes it a metadata layer over someone else's bucket rather than storage itself. |
| Composes with | Unlimited projects per certified user. The interesting chain is the inverse: point Synapse at a custom S3/GCS location and you get a free DOI-style sharing and permissions layer over any bucket you already have. |
| Reliability | Certification gate plus no published quota means capacity is discretionary; large uploads are known to be throttled/queued without a documented ceiling. Treat quota as unverified. |
