Amazon API Gateway vs WSO2 Choreo Connect

Amazon API Gateway is a cloud service for creating, publishing, maintaining, monitoring, and securing APIs that connect applications to backend services. It supports REST, HTTP, and WebSocket APIs, including real-time two-way communication. Integrations include AWS Lambda, Step Functions, Elastic Beanstalk, EC2, and public HTTP endpoints; HTTP APIs can also route requests to certain private services. API Gateway Portals provide managed spaces to discover, document, and govern REST APIs. Traffic controls include request throttling and configurable caching for REST APIs. The console integrates with Amazon CloudWatch for call, latency, and error metrics, alarms, and execution logs. Authorization options include IAM, Lambda authorizers, OIDC, OAuth 2.0, and other listed methods; REST API keys are optional. A free tier is available to new AWS customers for up to 12 months within monthly allowances, with excess usage charged at standard rates. Pay-as-you-go has no minimum fees or upfront commitments; the listed pricing note is From $1. WebSocket messages can be up to 128 KB and are metered in 32 KB increments.

WSO2 Choreo Connect is an open-source, cloud-native API gateway with Kubernetes support. It can run in cloud, on-premises, or hybrid environments that support Kubernetes. The architecture uses a Router, Enforcer, and Adapter, with Envoy Proxy handling traffic routing. The gateway supports REST and WebSocket APIs, listed as HTTP/1.1 and WebSocket, and provides API security, rate limiting, analytics, message mediation, and lifecycle management through WSO2 API Manager or standalone deployment. Authentication options include OAuth2 JWT tokens and API keys, with scope-based authorization. Named integrations and observability tools include WSO2 API Manager, Consul, Jaeger, Zipkin, and Azure Application Insights. Teams can publish analytics data, add custom filters, and build request or response interceptor microservices. Documentation points to GitHub releases and a Quick Start Guide for downloads. The Community plan costs nothing with GitHub community support.
