FastReact: FastAPI + React starter kit for AI-ready SaaS

Hi Product Hunt — I’m Harun, the maker of FastReact. I built it because FastAPI + React feels like a very practical stack for SaaS, and after building several AI SaaS products, Python became the obvious backend choice for me. Over time, I found the backend + SPA pattern worked better for the kinds of products I wanted to ship, so I built this as a foundation for my own future projects. I kept improving it, and once it felt production-ready, I decided to launch it as a product. FastReact is a FastAPI + React SaaS starter kit with auth, payments, multi-tenancy, and AI-ready usage metering already built in. fastreact I originally built the same architecture in Svelte first, then decided to build and maintain a React version too. If you want React on the frontend and Python on the backend without rebuilding the same SaaS plumbing again, this is for you.
