Mobile Framework Selection Decision Framework in 2026

Oflight Inc., based in Shinagawa-ku, Tokyo, has developed a comprehensive decision matrix to support selection of Flutter, React Native, Capacitor, and Tauri v2. In mobile app development projects, framework selection is one of the most important decisions determining success, faced by organizations of all sizes from startups in Minato-ku and Shibuya-ku to small and medium enterprises and enterprises in Setagaya-ku, Meguro-ku, and Ota-ku. This article defines 12 key evaluation criteria including performance, development productivity, cost, ecosystem, security, maintainability, team skills, and business requirements, providing quantitative and qualitative framework scoring. Based on analysis of over 300 actual project cases, we present recommended frameworks by industry, scale, and requirements, providing pre-implementation checklists, risk assessment sheets, and phased adoption roadmaps. Using this decision matrix enables framework selection that minimizes technical debt and achieves long-term success.

Evaluation Criterion 1: Performance and Responsiveness

Application performance is the most critical factor determining user experience. Flutter achieves smooth 60FPS animations and fast startup times through Dart code compilation to native code, with media apps in Shinagawa-ku improving user engagement by 25% (Score: 9/10). React Native requires optimization for complex UI and animations due to JavaScript bridge overhead, but achieves sufficient performance with proper tuning, with SNS apps in Minato-ku achieving performance comparable to native (Score: 7/10). Capacitor, being WebView-based, has inferior performance compared to native UI, but improvements are progressing through PWA optimization and WebAssembly utilization, with business apps in Shibuya-ku achieving acceptable performance (Score: 6/10). Tauri v2 achieves highest speed and smallest memory footprint through Rust's native performance and memory efficiency, with high-performance apps in Meguro-ku showing benchmark results exceeding native apps (Score: 10/10). Game apps in Setagaya-ku prioritize frame rate stability as a deciding factor for framework selection. IoT control apps in Ota-ku require real-time responsiveness directly related to safety.
