A simple, high-performance, zero-copy C++17 serialization and reflection library with no dependencies.
Cista is a C++17 serialization and reflection library that enables efficient (de-)serialization of native C++ data structures with zero-copy operations. It solves the problem of high-performance data persistence and transfer by allowing direct serialization to memory or filesystem, supporting complex and cyclic data types without requiring intermediate buffers or code generation.
C++ developers working on performance-critical applications such as game engines, GIS systems, network data transfer, or shared memory applications that require efficient serialization of complex data structures.
Developers choose Cista for its raw performance, minimal overhead, and simplicity—offering a single-header, dependency-free solution with support for native structs, automatic hash/equality derivation, and optional integrity checks, making it ideal for high-speed serialization scenarios.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Eliminates intermediate buffers by serializing directly to memory or filesystem, saving up to 50% memory as demonstrated in benchmark comparisons.
Works with existing C++ structs and classes, including non-aggregate types like derived classes, without requiring macros or code generation.
Includes serializable hash map and set based on Google's Swiss Table, optimized for speed in complex data handling scenarios.
Derives hash and equality functions automatically, reducing manual code for data structures as shown in the examples with cista_members().
Only compatible with C++17 and above, restricting use in legacy codebases or projects stuck on older compiler standards.
Lacks built-in support for protocol evolution or backward compatibility, unlike alternatives like Protocol Buffers, making data format changes risky.
Requires identical pointer width between serializing and deserializing systems, which can be a hurdle in cross-architecture deployments despite endianness support.
Cista++ is an open-source alternative to the following products:
MessagePack is an efficient binary serialization format that enables fast data exchange between multiple languages like JSON, but smaller and faster.
Protocol Buffers (protobuf) is a language-neutral, platform-neutral extensible mechanism for serializing structured data, developed by Google for efficient data interchange.
boost.serialization is a C++ library that provides serialization of C++ data structures to various formats including text, XML, and binary for storage or transmission.
FlatBuffers is an efficient cross-platform serialization library developed by Google, enabling fast data access without parsing/unpacking, often used in game development and high-performance applications.
cereal is a C++11 serialization library that provides a simple and efficient way to serialize data to JSON, XML, or binary formats for storage or transmission.
Cap'n Proto is a fast data interchange format and capability-based RPC system designed for high performance and low overhead.
