Tech Stack Evaluator
Technology stack evaluation and comparison with TCO analysis, security assessment, and ecosystem health scoring.
Before & after
Same prompt, same agent — the only difference is the skill.
That's a significant technical decision. Both React and Svelte have their strengths. React has a larger ecosystem and more job availability. Svelte is simpler to learn and produces smaller bundle sizes. You'd want to consider your team's expertise and the size of your codebase. There are trade-offs around performance, developer experience, and hiring. Migration costs can be high. You might want to evaluate your specific use cases. What are your primary concerns with React right now?
TECHNOLOGY STACK COMPARISON Context: current app 180K LOC React, 12 engineers, 2-year horizon TOTAL COST OF OWNERSHIP ANALYSIS Migration Cost Rewrite estimate: 6-8 months, 2 senior engineers full-time Engineer cost: 2 engineers * 8 months * 12K per month = 192K Opportunity cost: 2 engineers off roadmap = 16 features delayed Testing & QA: 6 weeks, 1 engineer = 36K Risk buffer (20%): 45.6K Total migration cost: 273.6K over 8 months Ongoing Maintenance Cost (5-year span) React ecosystem: active, 3+ major versions per year, job market abundant Svelte ecosystem: smaller, fewer library options, hiring harder Svelte cost multiplier: 1.4x (smaller pool, less training material) Year 1-2 React: 80K per engineer Year 1-2 Svelte: 112K per engineer (harder to hire) Difference over 5 years: 160K additional cost Performance Gain Bundle size: Svelte 40% smaller Initial load: React 2.8s → Svelte 1.9s (0.9s savings) End-user impact: minimal for web app Value: low Developer Experience React: steeper learning curve, massive library ecosystem Svelte: easier to learn, fewer options to choose from Value: low for experienced team Hiring Risk React engineers: easy to hire (market supply high) Svelte engineers: 3-4x harder, require React experience + ramp time Value: cost multiplier on future hiring VERDICT Total 5-year cost React: 700K Total 5-year cost Svelte: 986K Difference: 286K more expensive No migration recommended. Stay React. Invest optimization budget elsewhere.
