## What it is
Coost is a lightweight, cross-platform C++11 base library similar to Boost but much smaller (~1MB static library). It bundles coroutines, a JSON/RPC framework, logging, unit testing, benchmarking, flag parsing, and string/time/file utilities.

## Use cases
- add go-style coroutines to a C++ project
- lightweight alternative to boost for C++ utilities
- fast JSON parsing and serialization in C++
- set up unit tests and benchmarks for C++ code
- build a JSON RPC service in C++
- high-performance logging for C++ applications
- parse command line flags and config files in C++

## When to choose
- you want a compact all-in-one C++ utility library instead of pulling in many dependencies
- you need go-style coroutines or a coroutine-based network library in C++
- you want logging, JSON, RPC, testing, and flag parsing from a single small library

## When to avoid
- you need a battle-tested, standards-track library with broad ecosystem support like Boost
- your project requires a permissively audited license (license metadata is non-standard)
- you only need one narrow feature where a dedicated single-purpose library may be better maintained

## Facets
- artifact type: library
- maturity: active
- function: serialization, logging, rpc, testing, benchmarking, concurrency, json, cli, parser
- domain: developer-tools, backend, programming-languages
- platform: cpp, windows, cross-platform
- tags: boost-alternative, coroutines, c++11, base-library, networking, memory-allocator, linux, macos
