Figma is a powerful tool for creating digital designs and prototypes. It is completely free to use for both personal and commercial work. However, there are some limitations on the functionality that is available. For example, there is no support for vector illustrations or animations.
Additionally, some features, such as exporting to PDF or exporting as a file type, require an in-app purchase. Overall, however, Figma is a valuable tool for creating complex designs and prototypes.
