The fact that apps across multiple platforms support different Lottie specifications presents a clear issue, similar to how SVG has faced compatibility issues within the industry for decades. A cross-platform designed dotLottie player is highly appealing for addressing this issue. It is similar to how 3rd party apps hope to implement the same business logic across multiple products. With a dotLottie player, apps expect to have the same killer motion design among the different targets!

To add a note, At the core of dotLottie is an super lightweight Lottie rendering engine(https://github.com/thorvg/thorvg). It is small enough (300kb) to run on low-spec devices like ESP, MPU, and MCU (it's proven within LVGL https://lvgl.io/ framework), and we can expect the hardware acceleration features for high-performance devices, including nested multi-threading task scheduler, SIMD, OpenGL, and WebGPU (though some of them are under the beta dev but aggresively working on). It has proven stable to be used in practical applications (even it's in Godot game engine) across various devices and also offers a web player through WebAssembly. We can check the ThorVG-based Lottie web player can be completed in less than 500KB (You can directly test Lottie animations at www.thorvg.org/viewer). This ensures the scalability of the dotLottie player from low-spec device environments to high-spec web environments & apps.
