Web App Developer Initiative
In 2015, Mozilla launched an initiative to energize web app development, the Web App Developer Initiative (WADI). The initiative focused on several emerging Web APIs -- service workers, web push, and the W3C web app manifest -- and invited the participation of browser makers, web frameworks, cloud service providers, and content providers.
The WADI initiative has now ended, but Mozilla continues to develop and evangelize these and other modern web app development technologies along with the other participants. What unites all these disparate parties is a belief in the power of web apps that work reliably with bad networks, reengage users with notifications, and can be installed like native apps. We believe developers will use these technologies to deliver experiences that will redefine the role of the web.
For more information about these APIs and their availability in Mozilla products, see the Mozilla Developer Network's App Center and Firefox Platform Status.
