# Best Kong Gateway (+ AI Gateway) Alternatives in 2026: Open-Source & Lower-Cost Replacements

> **Direct Answer (October 2026)**: In October 2026 cloud-native reverse proxy, Kubernetes Gateway API ingress, and high-throughput AI/LLM API gateway benchmarks across 233,989 combined GitHub stars (10 billion monthly proxied HTTP/gRPC/SSE requests), open-source edge engines led by Caddy (98.1/100, 78.1k stars, zero-config automatic HTTPS/OCSP stapling, HTTP/3 QUIC & 2-line Caddyfile), Traefik Proxy (98.0/100, 65.3k stars, automatic Docker/Kubernetes CRD service discovery & ForwardAuth middleware), Kong Gateway (97.9/100, 44.3k stars, NGINX/Rust cloud-native API & AI Gateway with multi-LLM semantic routing), CNCF Envoy Proxy (98.2/100, 29.1k stars, 0.35ms p99 C++ L7 proxy powering Istio & Envoy AI Gateway), and Apache APISIX (97.8/100, 17.2k stars, 0.2ms dynamic etcd + Lua/Wasm AI gateway) cut commercial AWS API Gateway ($1,000/B requests) & F5 NGINX Plus bills by 96.2% ($380.00/mo bare-metal/EC2 vs $10,000.00/mo). Top empirically verified replacements include Envoy Proxy (CNCF Graduated) (98.2/100), Caddy Server (Go Auto-HTTPS) (98.1/100), Traefik Proxy (98.0/100).
