Who This Tool Is For

SaaS founders, architects, and CTOs deciding between multi-tenant and single-tenant architectures.

Why We Built This Tool

Multi-tenant vs single-tenant is often framed as security-only, but it is fundamentally a cost and unit-economics decision.

What Problem It Solves

Architecture guessing. See cost difference upfront.
Scaling surprises. Single-tenant at 10 customers vs 1000 customers.
Migration timing. Find the crossover where models flip.

See our architecture consulting or serverless SaaS development.

Frequently Asked Questions

Can I switch later?

Yes, but migration is expensive — this helps you decide upfront.

Is there a middle ground?

Hybrid models (multi-tenant SMB, single-tenant enterprise) are common.

What about database choice?

This models overall architecture; DB choice affects multi-tenant cost more.
