Greenbird is an open-source, distributed, and scalable high-performance HTTP/S server and reverse proxy. It is designed to handle a large number of concurrent connections and high traffic loads, making it suitable for demanding web applications and APIs.

Key Features:

• High Performance: Greenbird is built with a non-blocking, event-driven architecture that allows it to efficiently handle numerous simultaneous connections.
• Scalability: The server can be scaled horizontally across multiple machines to distribute the load and improve performance.
• Reverse Proxy: Greenbird can act as a reverse proxy, routing incoming requests to backend servers. This can be used to improve security, load balancing, and caching.
• HTTP/S Support: It supports both HTTP and HTTPS protocols, enabling secure communication.
• Configuration: Greenbird is typically configured via configuration files, allowing for flexible customization of its behavior.
• Open Source: Being open source, the source code is available and can be modified and distributed under its license. This allows for greater control and customization.
• Asynchronous Programming: The server leverages asynchronous programming principles to maximize resource utilization and responsiveness.
• Load Balancing Algorithms: Implements various load balancing algorithms to distribute traffic across backend servers efficiently, such as round-robin or least connections.
• Health Checks: Can be configured to perform health checks on backend servers and automatically remove unhealthy servers from the load balancing pool.
• Caching: Supports caching of frequently accessed content to reduce load on backend servers and improve response times.
• WebSocket Support: Enables real-time bidirectional communication between clients and the server using the WebSocket protocol.

Typical Use Cases:

• Serving static content (e.g., images, CSS, JavaScript)
• Acting as a load balancer for web applications and APIs
• Improving security by hiding backend servers
• Caching content to improve performance
• Facilitating WebSocket communication
• Handling high-traffic websites and applications.
