Agentic AI Music Boilerplate: Production-ready AI SaaS template with React & FastAPI

Hi Product Hunt! 👋 I’m Mykola, a junior full-stack developer from Ukraine, and I’m super excited to share this project with you! When learning how to integrate LLMs into web apps, I noticed most tutorials just teach you how to build a basic text chatbot. I wanted to build something more interactive—an Agentic UI, where the AI can suggest actions (like searching for a specific song) and natively trigger them in the React frontend. I built this Music Discovery Engine to figure out that architecture. It uses: ⚙️ FastAPI & Python for a lightning-fast backend. 🔍 SentenceTransformers for hybrid semantic search. ⚛️ React with a custom dark neon Glassmorphism design. 🐳 Docker so it can be deployed anywhere in 1 click. I also built in strict error handling so that when the Gemini API hits a 503 limit, the app intercepts it gracefully instead of crashing. I packaged the entire project as a ready-to-use boilerplate. Whether you want to launch an AI startup, or just study how to wire an Agentic AI to a React UI, this template will save you dozens of hours. I'd love to hear your feedback on the code architecture or the UI design! I'll be here all day to answer your questions. 🚀
