I check the license, but I don’t understand anything.
From here - GitHub - Codestar/codestar-framework: A Simple and Lightweight WordPress Option Framework for Themes and Plugins in License part:
You can bundle the framework ( both free and premium ) in your free theme/plugin that you publish inside WordPress.org theme/plugin directory or in premium theme/plugin that you sell on your own website or in marketplaces like ThemeForest. This framework is licensed 100% GPL.
