Freemius offers features like checkout optimization, affiliate program management, and detailed analytics to help developers grow their revenue. It supports multiple pricing models including one-time purchases, subscriptions, and lifetime licenses. The service integrates directly into WordPress plugins and themes through an SDK, providing a seamless user experience for end customers.
