Why I Ditched Modern Frameworks for a High-Performance Multilingual Utility (100/100 Lighthouse)

Hi everyone! I just hit a major SEO milestone with www.barkodkarekod.com and wanted to share why Vanilla JS was the key:
100/100 Performance: Ditching frameworks gave me a perfect Lighthouse score. Speed is the best UX.
SEO Power: Already reached Google Page 3 for global 'Amazon FBA' keywords with 112 indexed pages.
New Feature: Added a real-time 'Validate' tool so users can verify QR codes instantly.
For simple utilities, sometimes 'No-Framework' is the ultimate competitive advantage.
What’s your take on Vanilla JS for production in 2026?
