🎶 AI Music Generation SaaS Overview

This project is a full-stack SaaS application that lets users generate original music with the help of AI. By entering text prompts, lyrics, or stylistic descriptions, users can create unique tracks complete with vocals, instrumentals, and even custom artwork.

The system is designed as a production-ready SaaS, featuring user authentication, a credit-based payment model, and background processing queues to scale efficiently. All integrations are built using free-tier services, so it’s easy to set up and run without extra cost.
