Pros
LeanTween is widely praised for its intuitive, lightweight, and high-performance API that significantly reduces the overhead associated with Unity's native coroutines and Animation system. Developers appreciate its ease of use, clean syntax, and ability to handle complex UI and spatial transitions with minimal code, making it a staple for mobile game development where memory efficiency is critical.
While historically a gold standard for free tweening, its abandoned state and increasing incompatibility with modern Unity versions make it a dangerous liability for professional production environments.
Cons
The asset suffers from a lack of active maintenance, with no significant updates in years, leading to unresolved bugs, compatibility issues with newer Unity versions (including Unity 6 and Domain Reload), and broken documentation links. Users have reported random NullReferenceExceptions, stuttering on Android, and potential project-breaking behavior during imports, compounded by a lack of official support for modern Unity features.
