It implements event-driven non-blocking APIs for TCP, UDP, HTTP, WebSocket, MQTT. It has been designed for connecting devices and bringing them online. On the market since 2004, used by vast number of open source and commercial products - it even runs on the International Space Station! Mongoose makes embedded network programming fast, robust, and easy. - [Download Mongoose Source Code here](https://www.cesanta.com/download.html) - [Read Mongoose documentation](https://cesanta.com/docs/) Connectivity is vital for software and embedded devices, but there are many pitfalls to consider when embedding a web server.
