## Overview

- **Who it's for**: Developers building web and mobile app backends who want a managed Parse Server platform instead of running their own infrastructure, ranging from solo developers prototyping on the free tier to teams needing dedicated production resources.
- **What you get**: A managed MongoDB-backed database with auto-generated REST and GraphQL APIs, built-in user authentication with social login, file storage, Cloud Code serverless functions, real-time LiveQuery subscriptions, and a dashboard for managing data, users, and ACL/Class-Level-Permission security settings.
- **How it works**: Developers create an app in the Back4app dashboard, obtain app keys, and connect using a Parse SDK (JavaScript, React Native, Flutter, iOS, Android) or the REST/GraphQL APIs; data is modeled as Parse.Object classes, business logic runs as Cloud Code functions, and Back4app hosts, scales, and secures the underlying Parse Server infrastructure.
