Ffjson
Generates static MarshalJSON/UnmarshalJSON functions for Go structs, providing 2-3x faster JSON serialization with drop-in replacement.
What is Ffjson?
ffjson is a Go tool that generates static MarshalJSON and UnmarshalJSON functions for struct types, providing 2–3 times faster JSON serialization and deserialization compared to the standard library's reflection-based approach. It solves performance bottlenecks in JSON-heavy applications by creating optimized code at build time while remaining a drop-in replacement for encoding/json.
Go developers working on high-performance applications where JSON serialization is a bottleneck, such as web servers, APIs, or data processing pipelines.
Developers choose ffjson because it delivers significant speed improvements without requiring code changes, seamlessly integrates with existing projects, and offers fine-grained control over serialization behavior through code generation.
