The SAFE stack is an open-source, free, flexible end-to-end, functional-first stack for cloud-ready web applications that emphasizes type-safe programming.
The SAFE stack allows you to develop web applications almost entirely in F#, without needing to compromise and shoehorn your codebase into an object-oriented framework or library, and without needing you to be an expert in CSS or HTML to create compelling, rich client-side web applications.
SAFE provides developers with a simple and consistent programming model for developing rich, scalable web-enabled applications that can run on multiple platforms. SAFE takes advantage of F# mix of a functional-first experience backed by the powerful and mature .NET framework to provide a type-safe, reliable experience that leads to the "pit of success".

Saturn is a web development library written in F# which allows you to easily create both server-side MVC applications as well as web APIs. It runs on top of two other components: Giraffe, an F#-specific library for writing functional-first web applications.,Microsofts ASP .NET Saturn, via Giraffe, provides very good integration with other ASP.NET Core components such as authentication.
Azure is a comprehensive set of cloud services that developers and IT professionals use to build, deploy and manage applications through a global network of data centres. Integrated tools, DevOps and a marketplace support you in efficiently building anything from simple mobile apps to Internet-scale solutions.
Elmish is a set of simple abstractions for writing user interfaces in F# applications in a functional style following the model-view-update architecture made famous by Elm. The Elmish library is not coupled to any specific view engine, but is intended for use in conjuction with a DOM/renderer such as React/ReactNative or VirtualDOM.
