Java JSON Libraries

Is Google's Gson library still recommended for new projects in 2025?

Gson remains viable but newer alternatives are often preferred for new projects in 2025. Gson is stable, well-documented, and widely used, making it a safe choice. However, Moshi offers better Kotlin support with null safety and is more actively maintained. Jackson provides superior performance for large datasets and extensive feature sets for enterprise applications. For Android projects, Moshi integrates better with modern Kotlin codebases. Gson lacks built-in support for Kotlin data classes and requires additional configuration for null handling. The library is in maintenance mode with fewer updates compared to alternatives. Choose Gson if maintaining consistency with legacy code or for simple Java projects. For greenfield projects, consider Moshi for Android/Kotlin or Jackson for backend services. Use our JSON Editor at jsonconsole.com/json-editor to test and validate your JSON structures regardless of which library you choose. The decision depends on language, platform, and specific requirements.
