Which framework offers faster cold & warm startup times and smoother animations in 2025—Flutter or React Native?

Comparing Flutter and React Native on startup speed, animation fluidity, and memory usage based on 2025 benchmarks.

• Flutter achieves superior performance: cold start ~1.2s, warm start ~85 ms, consistently delivering 60–120 fps, with lower memory consumption (≈148 MB) due to Impeller engine and AOT compilation. • React Native, despite optimizations like Fabric and Hermes engine, tends to have slower startup (~1.4–1.6s), lower animation frame rates (~45–52 fps), and slightly higher memory usage (~162 MB).
