Zephyr is a real-time operating system (RTOS) developed in-part from the Virtuoso OS, which was first developed in the 1990s, and is designed to bring a simple user experience to microcontrollers.
A recent project aims to make it easier for users to access their Zephyr microcontrollers through a browser, by providing a web server that runs on the Zephyr operating system, and a REST API for clients to communicate with it.
The project also makes use of WebSocket to update web pages in real time, something necessary for sensors that continuously update data.
One commentator pointed out the advantages of Zephyr over RTEMS, another well-established RTOS, saying that Zephyr is more modern and adaptable, and has better support for newer hardware.
They also note that Zephyr is the new RTOS core for Arduino, suggesting its rise in popularity.
