Mashery was sunset January 2024, Kong doubled down on Konnect cloud, and Envoy Gateway graduated from CNCF. This piece compares 15 options by category, features, pricing, and real-world usage — Toss internal gateway, Kakao API platform, Mercari and ZOZO microservices. Rate limiting, auth, schema validation, caching, BFF patterns, OpenAPI 3.1 and AsyncAPI 2/3, gRPC and WebSocket support, and how gateways get redefined in the LLM era.

Mashery는 2024년 1월에 일몰됐고, Kong은 Konnect로 클라우드를 강화했으며, Envoy Gateway는 CNCF Graduated로 올라갔다. 이 글은 15가지 옵션을 분류·기능·가격·실제 사용 사례로 비교한다 — 토스의 자체 게이트웨이, 카카오의 API 플랫폼, Mercari·ZOZO의 마이크로서비스 진영까지. rate limiting·인증·schema validation·caching·BFF 패턴, OpenAPI 3.1과 AsyncAPI 2/3, gRPC·WebSocket 지원, 그리고 LLM 시대에 게이트웨이가 어떻게 재정의되는지.
