PRODUCTION CODE IMPLEMENTATION
// PostgreSQL Tenant-Isolation Context Hook
export async function withTenantContext<T>(tenantId: string, operation: () => Promise<T>): Promise<T> {
return await db.$transaction(async (tx) => {
await tx.$executeRawUnsafe(`SET LOCAL app.current_tenant_id = '${tenantId}';`);
return await operation();
});
}Architecture Comparison: Custom Engineering vs. Generic Agency
| Feature | Generic Agency / Page Builder | Jyotirmay's Custom Architecture |
|---|---|---|
| Data Security | Shared tables with prone manual WHERE clauses | PostgreSQL Row-Level Security (RLS) enforced at database level |
| Scaling Ceiling | Slows down significantly after 50+ tenants | Optimized connection pooling supporting 10,000+ active tenants |
| Custom Domains | Requires complex manual server configurations | Automated Cloudflare for SaaS SSL edge provisioning |
Frequently Asked Questions & Technical Scope
What is the best architecture for multi-tenant SaaS?
For most B2B SaaS products, a shared database with PostgreSQL Row-Level Security (RLS) and tenant context middleware provides the best balance of cost efficiency, performance, and bulletproof security.
Can tenants connect their own custom domains?
Yes. We engineer automatic SSL issuance and reverse proxy routing so your clients can point their CNAME records directly to their branded workspace.
