Apache Cordova is a set of device APIs that allow a mobile app developer to access native device function such as the camera or accelerometer from JavaScript. Combined with a UI framework such as jQuery Mobile or Dojo Mobile or Sencha Touch, this allows a smartphone app to be developed with just HTML, CSS, and JavaScript.

When using the Cordova APIs, an app can be built without any native code (Java, Objective-C, etc) from the app developer. Instead, web technologies are used, and they are hosted in the app itself locally (generally not on a remote http server).

And because these JavaScript APIs are consistent across multiple device platforms and built on web standards, the app should be portable to other device platforms with minimal to no changes.

You can use pywebview either with a lightweight web framework like Flask or Bottle or on its own with a two way bridge between Python and DOM.

pywebview uses native GUI for creating a web component window: WinForms on Windows, Cocoa on macOS and QT or GTK on Linux. If you choose to freeze your application, pywebview does not bundle a heavy GUI toolkit or web renderer with it keeping the executable size small.

pywebview is a BSD licensed open source project. It is an independent project with no corporate backing. If you find pywebview useful, consider supporting it. More donation options are outlined on the Donating page.
