About:
Flatcc is a command-line compiler and C library for FlatBuffers, a fast binary serialization format. It allows developers to define data structures in schema files and generate efficient C code for reading and writing serialized data without parsing overhead. Its main value is providing high-performance, zero-copy data access ideal for resource-constrained or latency-sensitive applications.

Key Features:

Zero-copy deserialization for maximum performance
Lightweight C89 library with no external dependencies
Supports schema evolution and cross-language compatibility
Portable across embedded systems, desktops, and servers

Use Cases:

High-performance embedded systems and IoT devices
Game development for efficient asset loading
Real-time data pipelines and microservices
Cross-platform data exchange between heterogeneous systems

Alternatives:

flatbuffers – Official Google implementation; larger footprint and C++ focus vs. flatcc's C89 minimalism
