async_simple is a lightweight C++20 library providing easy-to-use asynchronous programming components, including Lazy (stackless coroutines), Uthread (stackful coroutines), and Future/Promise. It is part of Alibaba's yalantinglibs suite and is nearly header-only, installable via vcpkg or CMake.

Use cases

• write asynchronous C++ code with C++20 coroutines
• lazy evaluation with stackless coroutines in C++
• lightweight stackful coroutines for concurrent tasks
• modern future/promise alternatives for C++
• async file processing in C++
• high-performance concurrent networking components

When to choose

• you need C++20 coroutine support in a C++ project
• you want a lightweight, mostly header-only async library
• you need both stackful and stackless coroutine options
• you're building high-performance C++ services with async I/O

When to avoid

• your compiler is older than gcc 10.3 or clang 10
• you need a full networking framework rather than async primitives
• your project targets C++ standards before C++20
