DSL-JSON is a high-performance JSON serialization library for the JVM (Java, Kotlin, Scala, Android) with compile-time databinding via annotation processors. It works directly on bytes for fast, allocation-friendly serialization and deserialization of POJOs.

Use cases

• serialize and deserialize POJOs to JSON on the JVM
• parse JSON on Android with minimal footprint
• stream large JSON lists with low memory usage
• replace Jackson with a faster JSON codec
• bind JSON to existing object instances to reduce GC pressure
• support Scala collections and Kotlin classes in JSON serialization

When to choose

• JSON throughput and low allocation are critical
• you want compile-time code generation instead of reflection
• targeting Android or other size-constrained environments
• you need streaming deserialization of large JSON arrays

When to avoid

• you need extensive ecosystem integrations and third-party module support like Jackson offers
• you prefer runtime reflection with zero annotation processing
• you need converters for legacy types like Joda out of the box
