Multi-Tenant SaaS2025Shipped
Blackgrid
Multi-tenant inventory SaaS with isolation enforced in middleware.
One deployment serving many independent businesses. Tenant isolation is enforced centrally rather than left to each view: tenant IDs are signed into the JWT and checked on every tenant-scoped route, and the X-Tenant-ID header is stripped on cross-origin requests to block forgery.
