## What it is
Bebop is a high-performance, typesafe binary serialization format with a schema language and code generator (bebopc) that produces optimized code for C#, TypeScript, Rust, C++, Dart, Python, and Go. It also includes Tempo, an RPC framework for building efficient APIs, and claims to be significantly faster than JSON and Protocol Buffers.

## Use cases
- serialize structured data faster than JSON or protobuf
- generate typesafe serialization code from schemas for multiple languages
- build efficient RPC APIs for real-time applications
- reduce payload size and latency in cloud gaming or game networking
- share a single schema across C#, TypeScript, and Rust services
- marshal messages with zero-copy decoding in performance-critical code

## When to choose
- you need blazing-fast binary serialization across several languages
- you want a simpler, faster alternative to Protocol Buffers
- you're building real-time or latency-sensitive systems like games or streaming backends
- you want generated, typesafe code with a tiny runtime and zero dependencies

## When to avoid
- you need human-readable data formats or easy debugging with plain text
- your ecosystem requires a widely adopted standard with broad third-party tooling
- you need rich schema evolution features like protobuf's field deprecation semantics
- your language isn't among the supported targets and you can't write an extension

## Facets
- artifact type: library
- maturity: active
- function: serialization, rpc, compiler, parser
- domain: developer-tools, apis, performance
- platform: cross-platform, c, rust, cpp, python, go, cli
