The Machine Room · Under the Hood
The biggest question in AI infrastructure right now isn’t what to build — it’s whether to build at all. We run our entire operation on a single GCP instance with MCP servers and custom pipelines at near-zero marginal cost. But that approach isn’t right for everyone.
This simulator models three scenarios — 100% SaaS/API, Hybrid with MCP servers, and Full Build — and calculates monthly costs, 3-year total cost of ownership, and break-even timelines based on your actual numbers.
Input your current marketing spend, team size, and content volume to see which infrastructure approach delivers the best ROI for your situation.

Your ROI Comparison
3-Year Total Cost of Ownership
Break-Even Timeline
When Full Build investment is recovered through API cost savings
Hidden Costs to Consider
Vendor Lock-in: SaaS/API providers can increase pricing or shut down services. Full Build gives you control.
Scaling Limitations: API rate limits and costs scale directly with volume. Full Build scales incrementally.
Maintenance Burden: Full Build requires ongoing updates, security patches, and infrastructure management.
Knowledge Silos: Custom systems create dependency on specific developers. SaaS is more portable.
Integration Costs: All scenarios require integration time. Full Build often requires more custom work.

Recommendation: SaaS/API Approach
For your current scale, SaaS/API is the most cost-effective solution. You benefit from:
No upfront infrastructure costs
Minimal maintenance overhead
Easy scaling as your team grows
Access to latest AI models automatically
Action: Start with Claude API, ChatGPT API, and managed tools to validate your workflows before investing in infrastructure.
`;

Recommendation: Hybrid Approach
You have enough volume to justify some custom infrastructure. A hybrid approach:
Reduces API costs by ~50%
Requires only part-time development
Provides flexibility with MCP servers
Balances control with simplicity
Action: Set up a small GCP VM with MCP servers for high-volume workloads while keeping SaaS for specialized tasks.
`;
} else {

Recommendation: Full Build
Your volume justifies full infrastructure investment. Full Build offers:
Maximum cost savings at scale
Complete control and customization
Zero vendor lock-in
Lowest operating costs at 3+ years
Action: Invest in a full infrastructure stack with dedicated development resources. Break-even occurs in ~${scenarios.breakEvenMonth} months.
