Reflex

Reflex lets you write web applications in pure Python without touching JavaScript or frontend frameworks. The platform uses AI agents to understand your Python code and automatically compiles it to a React frontend and FastAPI backend, generating the full tech stack on the fly.

Reflex fits developers who want to stay in Python for the entire project and teams building internal tools or prototypes quickly. It's especially useful if you're already comfortable with Python data science or backend work but want to ship a web interface without learning React.
