## What it is
Facebook's evolved branch of Apache Thrift, providing a serialization and RPC framework with a rewritten compiler and a fully asynchronous C++ Thrift server. It generates client/server stubs and serializable data structures across languages with strong C++, Python, Hack, and Java support.

## Use cases
- build high-performance RPC services in C++
- serialize structured data across languages
- generate client and server stubs from Thrift IDL files
- run an asynchronous Thrift server for microservices
- serialize records on disk for storage systems

## When to choose
- you need a battle-tested RPC framework at large scale, as used at Facebook
- you want cross-language serialization with a schema/IDL
- you need a fully asynchronous C++ server

## When to avoid
- you need vanilla Apache Thrift compatibility, since this branch has diverged
- your stack doesn't include C++, Python, Hack, or Java
- you want a simple REST/JSON API instead of binary RPC

## Facets
- artifact type: library
- maturity: active
- function: rpc, serialization, http-server
- domain: microservices, backend, apis, developer-tools
- platform: cpp, python, windows, cross-platform
- tags: thrift, facebook, async-server, idl, microservices, code-generation, linux, macos
