This demo shows how Sirko Engine can provide better experience to users by using Progressive Web App features

The site is static, but it tries to pretend that there is some work on the backend and it is dynamic. If you follow the given prediction in the left box, you will see the improved page load. Otherwise, it will take time (0.5-1 sec) to show content to you. If you want to inspect response time, you can install a page load time Chrome extension or open Dev Tools. Also, if you go offline, you will see that the site is capable to work offline. The offline feature is also managed by Sirko Engine.
