Base44 Backend is an AI-first backend platform that lets teams build, connect, and run production-grade applications without managing infrastructure. It handles data, logic, integrations, and permissions behind the scenes, allowing developers to focus on solving real problems and shipping more products.

The platform offers AI Agents optimization with CLI tools designed for leading AI agents like Claude Code and Cursor, featuring instant Skills that reduce rework and speed up deployment. It includes Authentication & Identity with Google OAuth readiness and support for custom auth flows without needing separate auth providers. Database & Entities functionality allows defining data models in code while Base44 handles storage, validation, migrations, and queries with full TypeScript support.

Permissions & Security features include built-in row-level security that defines who can read, write, or delete data, enforced across all clients. Connectors & Integrations provide ready-to-use integrations for AI, email, files, and images, plus OAuth connectors for secure third-party API access. Backend Functions enable running secure server-side code for sensitive operations including accessing secrets, calling external APIs, and handling business logic safely.

Base44 uses an AI-first approach where AI isn't an add-on but the core interface. Developers describe what they want to build, and the backend is created and updated automatically. AI helps generate logic, adapt to changes, and reduce repetitive work, allowing teams to move from idea to working system without waiting for long dev cycles.

The platform enables faster shipping of production-grade applications by eliminating backend setup and configuration requirements. It supports building tools that organizations can depend on, not just prototypes or experiments, with reliability, scalability, and security features expected from modern backend systems.

Base44 targets developers building applications with AI agents, particularly those using Claude Code and Cursor. It's designed for teams wanting to ship full-stack apps faster without managing infrastructure, with deployment handled through simple CLI commands.
