Back4app

Your Application's Backend, Simplified

Visit Back4app

Back4app is a low-code cloud platform for building and deploying application backends and full-stack web apps without managing infrastructure. It combines databases, authentication, APIs, server-side logic, real-time features, storage, and notifications in a single environment, with AI tools that can provision a backend and frontend from a description.

Core capabilities include MongoDB databases with relational models, geo-queries, and real-time sync; authentication with ACLs and role-based control; auto-generated GraphQL and REST APIs plus SDKs for JavaScript, iOS, Android, Flutter, and .NET; Cloud Functions written in JavaScript; GitHub-based web deployment with CI/CD; live queries; file storage with CDN delivery; and push and email notifications. An AI Agent generates full-stack apps, and MCP support connects to IDEs such as Cursor, VS Code, Windsurf, and Claude. The platform lists HIPAA, SOC 2, ISO 27001, and GDPR compliance.

Back4app is aimed at developers building backends and web applications, from prototyping through production. Pricing is organized into separate plans for the Backend Platform, Web Deployment Platform, and AI Agent, with free options for prototyping and dedicated plans for production apps.
