What is Reflex?
Reflex is a platform that turns a company's workflows, data, and requirements into real operational software. The AI Builder first plans the app, then builds actual routes, state, and screens, and runs tests before handing it over. It connects to existing systems such as databases, models, APIs, and authentication, and can be deployed on Reflex Cloud or your own cloud or on-premises. The underlying Reflex framework is an open-source (Apache 2.0) library that lets you write both frontend and backend in pure Python.
