Technology Stack Evaluator

When to Use

• You need to compare frameworks, cloud providers, or technology stacks across cost, ecosystem, security, or migration criteria.
• You are preparing a migration recommendation or technology selection spreadsheet with TCO and risk factors.
• The decision requires structured scoring (ecosystem health, security, performance).

When NOT to Use

• The request is for a quick coding question or implementation detail unrelated to evaluating tech stacks.
• The situation involves a single technology with no comparison or migration decision.
• You only need a high-level opinion without structured analysis or evidence.

Confidence Levels

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)
