## What it is
Fulcro is a full-stack, data-driven framework for building single-page web applications in Clojure and ClojureScript, built on React. It provides a normalized client-side graph data model with a consistent interface between the client and backend data sources like SQL, Datomic, GraphQL, or REST.

## Use cases
- build a single-page web application in ClojureScript
- develop a full-stack data-driven web app with a shared data model
- manage normalized client-side state for a React-based SPA
- connect a ClojureScript frontend to SQL, Datomic, or GraphQL backends
- rapidly prototype enterprise web applications with a cohesive architecture
- replace Om Next for data-driven web development

## When to choose
- you are a Clojure/ClojureScript developer building a full-stack SPA
- you want a batteries-included, data-driven architecture spanning client and server
- you prefer a normalized graph data model on the client with consistent backend interfaces
- you value local reasoning and production support in a web framework

## When to avoid
- your team does not know or want to learn Clojure/ClojureScript
- you need a lightweight library rather than an opinionated full-stack framework
- your project is a simple static site or mostly server-rendered pages
- you rely heavily on the mainstream JavaScript ecosystem's tooling and libraries
