Asio is a freely available, open-source, cross-platform C++ library for network programming.

A networking proposal based on Asio was submitted to the C++ standards committee in 2006 for possible inclusion in the second Technical Report on C++ Library Extensions (TR2).

[1] As of 2024, Asio continues to evolve, with ongoing contributions from the community and enhancements to its functionality.

The library is regularly updated to support the latest C++ standards and best practices in network programming.

Developers are encouraged to explore the extensive documentation and tutorials available on the official Asio website, which cover a wide range of topics, from basic usage to advanced features.
