About this project

Buster is an open-source browser extension designed to help users complete difficult CAPTCHA challenges, particularly reCAPTCHA audio challenges, using speech recognition. The extension is activated from its button at the bottom of the reCAPTCHA widget. The extension is listed for Chrome, Edge, Firefox and Opera. An optional client application can simulate user interactions and is described by the project as improving the extension's success rate. It is available for Windows, Linux and macOS and can be installed according to the extension's options. The project states that its accessibility-oriented goal is to reduce barriers caused by CAPTCHA challenges. Buster is released under the GNU General Public License v3.0.
