We’re very excited about Installable Web Apps, as they bridge the gap between native and web apps in a most elegant way: they allow you to build applications using the full web stack that run in the browser as well as outside of it, without sacrificing crucial functionality like hyperlinking, and without the need for app stores or gatekeepers. All these by adding a manifest.json to your website, https required.
