Learn BACKENDLESS with Real Code Examples

Updated Nov 23, 2025

Explain

Backendless allows developers and non-developers to manage backend services without writing server-side code.

It supports real-time databases, user management, API generation, push notifications, and serverless logic.

Ideal for startups, mobile app developers, and teams who want to focus on frontend while Backendless handles backend complexity.

Core Features

Real-time and persistent database

Serverless logic and cloud code functions

File storage and hosting

User management and authentication

API services with auto-generated endpoints

Basic Concepts Overview

Database tables represent app data

Serverless functions handle custom backend logic

APIs expose data and functions to clients

User management provides authentication and permissions

Push notifications and messaging for real-time communication

Project Structure

Database - tables, relations, and data

Serverless code - custom functions and logic

APIs - REST and GraphQL endpoints

User management - roles and authentication

Messaging - push notifications and chat

Building Workflow

Design database schema and tables

Create serverless functions for app logic
