What This Skill Does
The Tech Stack Evaluator helps users evaluate and compare different technologies, frameworks, and cloud providers. It provides data-driven analysis and actionable recommendations based on user-defined priorities. This is useful for making informed decisions about technology choices and migrations.
When to Use
Compare two technologies for a project Calculate the TCO of a tech stack Assess the health of a technology's ecosystem Evaluate the security of a framework Analyze a migration from one tech stack to another Compare cloud providers for a specific workload
Key Features
Compares technologies with weighted scoring Calculates 5-year total cost of ownership Assesses ecosystem health using Git Hub and npm data Evaluates vulnerabilities and compliance readiness Estimates effort for technology migrations Compares AWS, Azure, and GCP Evaluate and compare technologies, frameworks, and cloud providers with data-driven analysis and actionable recommendations.

| Quick Start |
Compare Two Technologies
Compare React vs Vue for a Saa S dashboard. Priorities: developer productivity (40%), ecosystem (30%), performance (30%).
Calculate TCO
Calculate 5-year TCO for Next.js on Vercel. Team: 8 developers. Hosting: $2500/month. Growth: 40%/year.
Assess Migration
Evaluate migrating from Angular.js to React. Codebase: 50,000 lines, 200 components. Team: 6 developers.
Input Formats
The evaluator accepts three input formats: Text - Natural language queries Compare Postgre SQL vs Mongo DB for our e-commerce platform. YAML - Structured input for automation comparison: technologies: ["React", "Vue"] use_case: "Saa S dashboard" weights: ecosystem: 30 performance: 25 developer_experience: 45 JSON - Programmatic integration { "technologies": ["React", "Vue"], "use_case": "Saa S dashboard" }

| High | 80-100% | Clear winner, strong data |
| Medium | 50-79% | Trade-offs present, moderate uncertainty |
| Low | < 50% | Close call, limited data |
When to Use
Comparing frontend/backend frameworks for new projects Evaluating cloud providers for specific workloads Planning technology migrations with risk assessment Calculating build vs. buy decisions with TCO Assessing open-source library viability
When NOT to Use
Trivial decisions between similar tools (use team preference) Mandated technology choices (decision already made) Emergency production issues (use monitoring tools)Technology Stack Evaluator Evaluate and compare technologies, frameworks, and cloud providers with data-driven analysis and actionable recommendations.
