## What it is
Wangle is a C++ networking library providing composable client/server abstractions for building protocols, application clients, and servers, similar to Netty and Finagle combined. It is built on folly's async I/O and futures, offering bootstraps, pipelines, and service filters for things like timeouts, rate limiting, and load balancing.

## Use cases
- build a custom TCP protocol server in C++
- write an async echo server and client
- add request timeouts and rate limiting to a service
- implement client connection pooling and retry logic
- build a Thrift or HTTP-style request/response service
- manage threadpools and handler pipelines for socket data

## When to choose
- you are building C++ network services and want Netty/Finagle-style abstractions
- you already use folly and want a higher-level async networking layer
- you need composable service filters for stats, timeouts, and retries

## When to avoid
- you need a simple one-off HTTP client or server with minimal dependencies
- your project cannot take on folly and fizz build dependencies
- you are not working in C++

## Facets
- artifact type: library
- maturity: active
- function: http-server, http-client, rpc, middleware, concurrency, networking
- domain: backend, networking, developer-tools, microservices
- platform: cpp, cross-platform
- tags: netty-like, finagle-like, client-server-abstractions, pipelines, futures, service-filters, load-balancing, tls, linux, macos
