Why is Moshi considered "safer" than Gson for Kotlin developers?

Moshi is safer for Kotlin because it respects Kotlin's null safety system, while Gson can bypass it. Moshi requires explicit handling of nullable types, preventing unexpected NullPointerExceptions. Gson uses reflection that ignores Kotlin's null annotations, allowing null values in non-null fields. Moshi's code generation (moshi-kotlin-codegen) provides compile-time safety versus Gson's runtime reflection. Moshi better handles Kotlin data classes, default parameters, and sealed classes. The library fails fast with clear errors for missing required fields rather than silently creating invalid objects. Moshi's API design aligns with Kotlin conventions and idioms. It enforces type safety that Gson circumvents, catching errors during development instead of production. For safety-critical applications, Moshi's strictness prevents subtle bugs.

Moshi's safety comes at minor performance cost but significantly improves code reliability in Kotlin projects.
