About QPub

What is QPub?

QPub is a high-performance real-time messaging platform that empowers developers to build instant digital experiences. It's a cloud-based publish/subscribe service that delivers messages with millisecond latency, handling scaling, reliability, and security automatically.

At its core, QPub eliminates the complexity of building real-time applications by providing a robust infrastructure that handles message delivery, connection management, and system scaling. Whether you're building a chat application, live dashboard, or IoT monitoring system, QPub provides the foundation for seamless real-time communication.

Key Features

QPub offers enterprise-grade features designed for modern applications. The platform provides real-time messaging through both WebSocket and REST APIs, ensuring compatibility with any technology stack. Built with a multi-tenant architecture, each project is completely isolated for security and data privacy.

Key capabilities include:

• Real-time messaging via WebSocket and REST APIs
• Multi-tenant architecture with complete project isolation
• Built-in authentication with API keys and JWT tokens
• Horizontal scaling supporting millions of concurrent connections
• Comprehensive monitoring with real-time stats and usage tracking
• Flexible deployment - cloud-hosted or self-hosted options

The platform includes detailed monitoring with real-time statistics and usage tracking, plus deployment flexibility that allows you to choose between cloud-hosted solutions or self-hosted infrastructure based on your specific requirements.

How It Works

QPub provides two primary integration methods for different use cases. WebSocket connections are recommended for real-time applications requiring bi-directional communication with persistent, low-latency connections. This approach is ideal for chat applications, live gaming, and real-time collaboration tools.

For administrative operations, configuration management, and non-real-time tasks, the REST API provides simple HTTP-based integration. This allows easy authentication, project management, and integration with existing systems without requiring persistent connections.

Pub/Sub Channels

Channels are the fundamental building blocks of QPub's messaging system, organizing messages into logical topics or categories. Publishers send messages to specific channels, while subscribers receive only messages from channels they've subscribed to, ensuring efficient message routing and delivery.

The system supports three primary message patterns:

• One-to-Many (Fan-out): Broadcasting to multiple subscribers - perfect for news updates, alerts, and live notifications
• Many-to-One: Data collection from multiple sources to a central system - ideal for IoT sensor networks and monitoring applications
• Many-to-Many: Collaboration between variable numbers of participants - commonly used in chat applications, multiplayer games, and collaborative editing tools

This flexible pattern system allows developers to implement any real-time communication scenario, from simple broadcasting to complex collaborative applications.

Use Cases

QPub serves diverse industries and applications requiring real-time communication. Chat applications and messaging systems benefit from the platform's low-latency message delivery and presence tracking capabilities. Live dashboards and monitoring systems can push real-time data updates to connected clients instantly.

Common applications include:

• Chat applications and messaging systems
• Live dashboards and monitoring systems
• IoT device communication
• Real-time collaboration tools
• Financial trading platforms
• Multiplayer gaming

IoT device communication leverages QPub's ability to handle massive numbers of concurrent connections while maintaining low latency. Real-time collaboration tools, financial trading platforms, and multiplayer gaming applications all rely on QPub's reliable message delivery and horizontal scaling capabilities to support growing user bases.

Billing

QPub offers flexible subscription plans designed to scale with your application's growth. Usage-based pricing covers connections, channels, messages, and bandwidth, ensuring you only pay for what you use. The platform integrates seamlessly with Stripe for professional billing management, providing detailed usage analytics and automated billing processes.

Billing features include:

• Usage-based pricing for connections, channels, messages, and bandwidth
• Stripe integration for professional billing management
• Detailed usage analytics and automated billing processes
