Introducing FlyWeb

For the past several months, a small team at Mozilla has been working on an experimental new Web API and an accompanying browser feature called FlyWeb.

What does it do?

In short, FlyWeb provides an API for web pages to host local web servers for exposing content and services to nearby browsers. It also adds the ability to discover and connect to nearby local web servers to the web browser itself. This feature allows users to find and connect to nearby devices with embedded web servers such as printers, thermostats and televisions as well as local web servers hosted in web pages via the FlyWeb API.

Enabling web pages to host local servers and providing the ability for the web browser to discover nearby servers opens up a whole new range of use cases for web apps. With FlyWeb, we can finally reach a level of richness in cross-device interactions previously only attainable via native apps. In addition, the built-in service discovery feature in the browser offers device makers and hob
