Cap'n Proto

Cap'n Proto is a high-performance data serialization and communication framework designed for efficient data exchange between different programs or systems. It allows complex data structures to be converted into a compact, binary format that can be quickly transmitted over a network or stored, then reconstructed with minimal overhead. Unlike traditional formats, Cap'n Proto enables direct access to data without unpacking or decoding, making it faster and more efficient—ideal for real-time applications like distributed systems, networked services, or high-performance software.
