A web and app development platform with an intuitive, no-code visual builder that also enables developers through extensible components and the ability to add custom code. Under the hood, FlutterFlow uses Google's Flutter for building cross-platform web and mobile apps, empowering non-technical users through a sleek and well-documented GUI builder. The service goes further by providing developers with the ability to add their own code and even exposing the code generated through the visual builder.
