Can I use this for cloud provider comparisons?

Yes, it specifically includes capabilities to compare AWS, Azure, and GCP for specific workloads based on cost, feature availability, and ecosystem compatibility.

What metrics are used for ecosystem health scoring?

The evaluator analyzes GitHub activity, npm download trends, community support, and library maintenance frequency to ensure the long-term viability of a technology.

Can I provide custom priorities for the comparison?

Absolutely. You can provide weighted priorities (e.g., 40% performance, 60% developer experience) via natural language, YAML, or JSON to tailor the recommendation to your specific needs.

How does the Tech Stack Evaluator calculate TCO?

It utilizes data-driven algorithms to project hosting fees, developer salaries, and growth rates over a five-year period to identify hidden costs and long-term financial impact.

Does it help with legacy migration planning?

Yes, it can estimate the complexity, line count impact, and required developer hours when planning a migration between different technology generations.
