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.
