Instapy is an open-source Instagram automation tool that allows users to automate various tasks on the platform, such as liking, commenting, following, and unfollowing. Instapy is written in Python and can be used on various operating systems such as Windows, Linux, and macOS. The tool uses the Instagram API to perform actions on the platform, but it also includes a feature that allows users to simulate human behavior to avoid triggering Instagram's automated systems. Instapy can be used to grow Instagram followers and engagement, but it's important to use it responsibly and within Instagram's terms of service to avoid being flagged or banned from the platform.
