Pushpin vs ws: What are the differences?

# Introduction
This Markdown code will outline the key differences between Pushpin and ws for easy reference on a website.

1. **Connection Handling**: Pushpin is designed for high-traffic websites and handles client connections efficiently by running on a separate server, while ws is a simple WebSocket implementation that handles connections directly within the application.
2. **Scalability**: Pushpin leverages a proxy-server architecture, making it easier to scale applications horizontally, while ws lacks this built-in scalability feature.
3. **Architecture**: Pushpin is built on the HTTP streaming framework, HTTP long-polling, or Webhooks, whereas ws is solely focused on WebSocket communication.
4. **Flexibility**: Pushpin allows for more complex routing and event handling through its integration with various backends like Redis and Kafka, whereas ws is more straightforward in its approach without these advanced features.
5. **Reliability**: Pushpin offers additional features like message queuing and caching, improving the reliability and performance of real-time applications, a feature not found directly in ws.
6. **Documentation**: Pushpin provides comprehensive documentation and support for developers to easily integrate and troubleshoot, offering a clear advantage over ws in terms of ease of use and implementation.

In Summary, the key differences between Pushpin and ws lie in connection handling, scalability, architecture, flexibility, reliability, and documentation. These differences make each option suitable for different types of real-time applications based on specific requirements and complexities.
