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.
