Roop is a one-click deepfake (face swap) tool available on GitHub and as a Stable Diffusion extension. It allows you to replace faces in videos with any other face using just one image. Installation instructions are provided on the GitHub repository for basic and GPU-accelerated setups. Running the program launches a user-friendly window where you can select source and target images/videos and initiate the face swap process.
