Vue 3.5 Migration Powers 40% Performance Gain and 22% Mobile Conversion Lift

Framework choice directly impacts business metrics: this migration proves that bundle size reductions translate to conversion gains. By cutting their main bundle from 187KB to 109KB and FCP by 58%, the team achieved 22% higher mobile conversion rates and recovered costs in 11 months. As enterprises evaluate framework decisions in 2026, this case demonstrates that strategic migrations—guided by benchmarking—can deliver revenue impact faster than incremental optimization.
