All four frameworks are open source with no basic licensing fees, but costs for surrounding services and tools differ. React Native commonly uses paid plans of Expo Cloud ($29-99/month) and OTA update services like CodePush. Flutter recommends Firebase integration, and BtoC app development in Minato-ku incurs monthly Firebase fees of tens of thousands of yen. Capacitor has paid services like Ionic Appflow and Capacitor Cloud, costing thousands to tens of thousands of yen per month including CI/CD integration. Tauri v2, being relatively new, has few dedicated paid services, but costs for IDE licenses (JetBrains products, etc.) and static analysis tools for Rust development must be considered. Enterprise companies in Shibuya-ku invest 100,000-500,000 yen monthly in security scanning tools and performance monitoring services, and these third-party costs should be comprehensively evaluated. Manufacturing apps in Ota-ku have reduced running costs by designing offline-first architectures that minimize cloud service dependencies.

Maintenance and Update Costs: Long-term Operational Burden

Considering the entire application lifecycle, maintenance and operation costs often exceed initial development expenses. React Native has frequent version updates and many breaking changes, with app development companies in Shinagawa-ku allocating 10-15% of development costs annually for 2-3 major update responses. Flutter has a relatively stable update cycle with high backward compatibility, keeping maintenance costs around 5-8% annually. Capacitor, being based on web technologies, requires responses to browser evolution, but gradual updates are possible with moderate maintenance burden.
