Compliance
Frameworks each provider states on its own site, each linked to its source.
| Framework | Firebase | Supabase |
|---|---|---|
| SOC 2 | Type II | Type II |
| ISO 27001 | Yes | Yes |
| HIPAA | -- | Yes |
| GDPR | Yes | Yes |
| PCI DSS | Some Firebase services only | -- |
Heads up: Each entry links to the provider's own statement. An attestation can cover one tier, one region or the platform alone rather than every service. Verify the scope before you rely on it. A dash means we found nothing to link to, not that the provider lacks it.
