    Bumblebee works by injecting a custom JavaScript program that intercepts client-side events and sends them to Bumblebee for analysis. In addition to front-end events, Bumblebee also captures internal browser events, which it then interprets to generate code in real time.

    Before settling on a desktop application, we contemplated designing Bumblebee as a browser extension.

Besides, the company’s security policy, which prohibited browser extensions, would have complicated the -deployment of an extension-based solution. The initial prototype used a C# -wrapper of the Chromium project instead of WebView.
