Learn what exists
behind the UI.
A practical map of the systems needed to move from application prototype to operating SaaS.
Multi-tenant SaaS
Tenant isolation, organizations, users, customer boundaries and shared-platform architecture.
Authentication & RBAC
Identity, roles, claims, permissions, field access and server-side enforcement.
SaaS Database Design
Records, tenancy, relational modeling, JSON configuration and safe expansion.
Billing Architecture
Plans, subscriptions, metering, entitlements, overages and downstream customer economics.
APIs & Webhooks
Expose capabilities safely and connect the SaaS to external systems and automation.
MCP & Agents
Let AI systems understand available tools and act through governed SaaS capabilities.
RAG & Vector Search
Chunk, embed, retrieve and ground AI responses in private enterprise knowledge.
Audit & Compliance
Track who did what, enforce boundaries and make sensitive workflows inspectable.
White-label SaaS
Brand, configure and resell software while preserving one maintainable platform.
Why StartMySaaS scores production architecture
A prototype can look complete long before it has the controls required for real customer data, recurring billing, user roles, failure recovery and long-term operations. The directory is designed around that gap.
The questions worth asking
- Can each customer be isolated cleanly?
- Are permissions enforced on the server?
- Can external systems use the platform safely through APIs?
- What happens when data, traffic and AI usage grow?
- Can the product be white-labeled or resold?
- How portable are the data and application logic?
- What is the total operating stack cost?
