Open-source alternatives to FastBinaryEncoding

Fast, idiomatic C# implementation of Flatbuffers

Simple Binary Encoding (SBE) - High Performance Message Codec

FlatBuffers is a cross-platform serialization library designed for performance-critical applications that require efficient, zero-copy data access. By organizing data in a structured binary format, it allows applications to read and write complex data structures directly from memory-mapped buffers without the need for intermediate parsing or temporary object allocation. The project distinguishes itself through a schema-driven approach that balances high-performance access with long-term data evolution. It utilizes a unique memory layout featuring relative offsets and inline fixed-size structu

Arrow is a cross-language development platform for in-memory data. It provides a standardized, language-independent columnar memory format designed to accelerate analytical operations and improve memory efficiency on modern computing hardware. By utilizing a schema-driven approach, the framework enables the efficient organization of both flat and nested data structures. The project functions as an analytical data processing engine that facilitates high-performance computation directly on memory-resident datasets. It distinguishes itself through a zero-copy architecture, which allows multiple

Fast and flexible serialization framework usable on undecorated classes.

Wirehair : O(N) Fountain Code for Large Data

Yet another protocol library like google protocol buffers , but simple and fast.

uPickle: a simple, fast, dependency-free JSON & Binary (MessagePack) serialization library for Scala

CapnProto is a zero-copy serialization framework and remote procedure call system. It serves as a C++ communication library providing a schema-based data interchange format that eliminates the need to encode or decode data before reading it from memory. The system enables high-performance data serialization and low-latency network communication. It supports cross-language data exchange by using a defined schema to ensure consistent binary representation across different platforms. The framework provides tools for implementing remote procedure calls, allowing functions to be invoked on a remo

Header-only library suitable for android/arm builds - Small, easy to understand - No pre-compilation of headers - No template specialization complexity

vproto can parse most (or maybe all...) of the proto2 spec. It compiles the Steam Protobufs generating valid code and also parses the protoc plugin protobufs (which can be found in plugin/google/protobuf). It can parse options, extensions, map fields and extends definitions but does not generate…

Yes, there are loads more of these types of config languages, but I wanted to make my own because the other options are overkill for my projects.

UltraJSON is a high-performance JSON library and parser written in C with bindings for Python. It provides a fast alternative to standard JSON processing for decoding JSON strings into native data structures and encoding data structures back into JSON strings. The library utilizes a C-based engine to reduce processing latency and increase throughput for JSON generation and parsing. It is designed to accelerate data pipelines and optimize the handling of JSON payloads.

Buf is a toolchain for managing the full lifecycle of Protocol Buffers schemas. It provides a set of tools for schema governance, including linting to enforce style guides, a breaking change detector to ensure backward compatibility, and a system for producing language-specific source code via local or remote plugins. The project distinguishes itself through a remote schema registry that centralizes the hosting, versioning, and distribution of Protocol Buffers modules. This registry allows for server-side enforcement of governance policies, such as blocking updates that introduce backward-inc
