libnode is a C++ implementation of Node.js. Just like Node.js, libnode provides non-blocking I/O, which enables you to develop scalable Web applications in C++. The memory management of libnode is automatic, based on either shared_ptr or bdw-gc. libnode is good to use on embedded devices because its system resource consumption is lower than Node.js.
