API proxies, API gateways, and reverse proxies serve distinct purposes in managing and routing web traffic, each with unique functionalities and advantages. An API proxy acts as a mediator between clients and APIs, adding functions like security and caching without altering the API itself, and is suitable for simple enhancements. In contrast, an API gateway provides a comprehensive platform for managing multiple APIs, offering advanced features like full lifecycle management, enhanced security, and improved developer experience, making it ideal for centralized control of APIs. Reverse proxies operate between clients and web servers, handling requests and responses while offering features such as load balancing, caching, and security, and are better suited for general web service management. The choice between these tools depends on specific project requirements, such as the need for API management, security levels, and whether the purpose is to manage APIs specifically or handle broader web traffic.
