The app is built with HTML, CSS and JavaScript using the Backbone.js framework and the Task Runner Grunt. You can switch between dark and light theme, whichever you like more. There are several options: update and install, show a notification or disable update at all.

The app can run either in browser, or as a desktop app in Windows, Mac OS and Ubuntu/Linux. It doesn't require any server or additional resources. Keeweb is an awesome hybrid desktop application to manager your passwords and is even compatible with KeePass databases.
