Score Breakdown

6 dimensions evaluated with transparent methodology

Performance
95 −5

Industry-leading performance through compile-time optimization

  • No virtual DOM - direct DOM manipulation
  • Compile-time optimization eliminates runtime overhead
  • Smallest bundle size among major frameworks (~3KB)
Why not 100%:
  • −2 Initial compile time can be slower for large apps
  • −2 Less runtime flexibility than virtual DOM approaches
Developer Experience
92 −8

Minimal boilerplate with intuitive syntax and excellent tooling

  • Single-file components with clean syntax
  • Less boilerplate than React/Vue
  • Svelte 5 runes for explicit reactivity
Why not 100%:
  • −4 Svelte 5 runes require relearning
  • −4 Fewer IDE extensions than React
Ecosystem
65 −35

Growing ecosystem with strong community momentum

  • Active Discord community (50K+ members)
  • SvelteKit for full-stack development
  • Growing component library ecosystem
Why not 100%:
  • −8 Significantly smaller than React ecosystem

Maintainability
90 −10

Stable core with Vercel backing and clear vision

  • Rich Harris leads consistent development
  • Vercel funding ensures long-term stability
  • Clear semantic versioning
Why not 100%:
  • −5 Svelte 4 to 5 requires code changes
  • −5 Smaller maintainer team
Cost Efficiency
95 −5

Open-source with minimal infrastructure requirements

  • MIT licensed, fully free
  • Smaller bundles reduce bandwidth costs
  • Lower memory usage reduces hosting costs
Why not 100%:
  • −2 Premium component libraries may be needed
  • −2 Training costs for new syntax
Compliance
85 −15

Growing enterprise adoption with solid security practices

  • No known critical vulnerabilities
  • Compile-time validation catches issues
  • CSP-friendly output
Why not 100%:

How we calculate these scores — transparent and reproducible

Deterministic Scoring

Same inputs always produce the same outputs. We use versioned lookup tables, not LLM opinions. Every score is explainable and reproducible.

Frequently Asked

Why doesn't Svelte score 100%?

No technology is perfect for every use case. Our scoring reflects real-world trade-offs. Svelte's main gaps are in ecosystem, where significantly smaller than react ecosystem.

What does confidence percentage mean?

Confidence (90%) indicates how much data we have to support the score. Higher confidence means more data points from multiple sources (GitHub activity, NPM downloads, security audits, community surveys).

How often are scores updated?

Scores are recalculated weekly using automated data pipelines. Major version updates trigger immediate recalculation. Last update: 2025-12-28.
