Bumblebee is a web browser that converts browser sessions into C# scripts for
playback. It eliminates the need for authoring browser automation scripts.

Bumblebee is a Windows Forms application written in C#. Web content is rendered
by the embedded Microsoft Edge browser (via WebView). The text editor on the
right is <a src="https://github.com/desjarlais/Scintilla.NET" class="external"
target="_blank" rel="noopener noreferrer">Scintilla.NET</a>. Users can
override the generated script at any point during the session. The users can
configure Bumblebee to debounce events, ignore hidden elements, etc.

Bumblebee works by injecting a custom JavaScript program that tracks user
interactions. The tracker intercepts and sends them to the Bumblebee backend as
events for analysis. In addition to the front-end events, Bumblebee also
intercepts events internal to the web browser, which it then interprets to
generate C# code for the Selenium WebDriver in real time.
