Glaze is an extremely fast, header-only C++ serialization and reflection library supporting JSON, BEVE, CBOR, BSON, CSV, MessagePack, TOML, YAML, and more, using compile-time reflection to serialize structs without macros or metadata. It also offers an in-development networking layer with REST servers, clients, and websockets.

Use cases

• serialize C++ structs to JSON without writing boilerplate
• parse JSON files into typed C++ objects
• convert between binary formats like CBOR and MessagePack
• build a fast JSON RPC API in C++
• read CSV data into structs
• generate JSON schemas from C++ types
• high-performance JSON parsing for latency-sensitive applications

When to choose

• you need one of the fastest JSON libraries available for C++
• you want macro-free serialization via compile-time reflection
• you need support for many formats (JSON, TOML, YAML, CBOR, MessagePack, etc.) in one library
• you want a header-only dependency with no exceptions or RTTI requirements

When to avoid

• you need a stable, finalized HTTP/REST networking API (it is still under active development)
• your project targets C++ standards older than C++23
• you need runtime-configurable serialization of dynamic schemas rather than static struct reflection
