Frequently asked
Shared schema or schema-per-tenant?+
Shared schema with row-level security is the right default for 90% of SaaS — simpler ops, cheaper, easier migrations. Schema-per-tenant only when isolation is a compliance hard requirement.
How do you prove tenant isolation works?+
Every PR runs a test suite that attempts cross-tenant access — every attempt must return 403 or empty. Deployments are blocked if isolation tests fail.
Can you migrate me from single-tenant to multi-tenant?+
Yes — staged migration with tenant_id added incrementally, dual-write period, backfill, then read-flip. Zero downtime achievable for most schemas.
