Core Viewpoint - In the process of digital transformation, cross-platform app development has become a necessity for enterprises, requiring compatibility with various operating systems and integration with mini-programs [1][2] Group 1: Challenges in Cross-Platform App Development - Enterprises face significant challenges in cross-platform app development, including difficulties in multi-end adaptation, high migration costs for mini-programs, increased app size affecting user experience, and weak management and maintenance capabilities [1][2] Group 2: Analysis of Mainstream Cross-Platform Development Tools - FinClip is highlighted as a leading tool for enterprises needing mini-program integration and multi-end adaptation, offering full coverage across various operating systems and devices, zero-cost migration for WeChat mini-programs, and a lightweight SDK [4][5] - mPaaS, while comprehensive, has limitations in mini-program support and may incur high costs for small teams due to its traffic-based pricing model [7][8] - Flutter is effective for mobile app development but lacks compatibility with mini-programs and has limited support for desktop systems [9][10] - React Native is suitable for mobile development but relies on third-party solutions for mini-program support and has challenges with domestic system adaptation [11][12] - WeChat Donut offers low migration costs for mini-programs but is limited to the WeChat ecosystem and lacks support for other operating systems [13][14] Group 3: Selection Recommendations - Companies should prioritize FinClip for needs involving mini-program collaboration and multi-end adaptation, as it effectively addresses technical challenges and reduces maintenance costs [15][16] - For lightweight mobile development, React Native may be considered, but with awareness of its limitations regarding mini-program integration [15] - WeChat Donut is a viable short-term option for enterprises heavily reliant on the WeChat ecosystem, though long-term costs and ecosystem limitations should be considered [15] - mPaaS may be suitable for pure mobile app development without mini-program needs, but its cross-end limitations should be noted [15] - Flutter is recommended for small teams with limited budgets focusing on simple mobile applications, but additional tools may be needed for future expansion [15]
