Open Source Alternatives to AWS API Gateway

An API infrastructure service that allows developers to create, publish, maintain, monitor, and secure APIs at any scale. It serves as a front door for applications to access data, business logic, or functionality from backend services, supporting containerized and serverless workloads as well as web applications. The service enables the creation of RESTful APIs and WebSocket APIs for real-time two-way communication. Capabilities include traffic management, CORS support, authorization and access control, throttling, and API version management. It also provides managed developer portals for the discovery, documentation, and governance of REST APIs across AWS infrastructure. Users can monitor performance metrics, data latency, and error rates through a dedicated dashboard using Amazon CloudWatch. The service is deployed as a fully managed AWS offering with a tiered pricing model based on usage.
