iguana is a C++17/C++20 header-only serialization engine built on compile-time reflection, supporting JSON, XML, YAML, and binary/protobuf formats. It can also leverage C++26 static reflection when compiled with a reflection-capable compiler.

Use cases

• serialize C++ structs to
• parse into C++ objects without runtime overhead
• convert structs to xml or yaml
• serialize objects to a protobuf-like binary format
• implement custom serialization formats via reflection
• fast zero-copy parsing in C++

When to choose

• you need high-performance serialization in modern C++ without code generation
• you want one library to handle multiple formats (, xml, yaml, binary)
• you can use C++17/20 and want compile-time reflection instead of macros or runtime introspection

When to avoid

• you need language-agnostic schema evolution like full protobuf ecosystem support
• your compiler is old and lacks C++17 support
• you need serialization across many languages, not just C++
