Generate API Gateway Architecture Diagrams with AI

Visualize your API gateway layer end-to-end — from client traffic entering the gateway through authentication, rate limiting, and routing to upstream backend services. Describe your gateway setup in plain English and get a professional architecture diagram ready for design reviews, security audits, or developer documentation.

The challenge

API gateways handle a lot: SSL termination, JWT validation, rate limiting with a shared Redis store, request routing to a dozen upstream services, protocol translation (REST to gRPC), and observability. Documenting all of this — and the order in which each plugin or policy runs — in a single coherent diagram is challenging without a tool that understands gateway architecture patterns.

The solution

Describe your API gateway setup the way you'd explain it to a new engineer:

"Kong Gateway in DB-less mode on Kubernetes. External traffic hits an AWS NLB that routes to Kong. Kong validates JWT tokens using Auth0 JWKS, applies rate limiting (1000 req/min per client) with a Redis cluster as the shared counter store, and routes to three upstream services: Order Service (REST), Product Service (REST), and Inventory Service (gRPC). Kong translates REST to gRPC for Inventory. Access logs go to Datadog."

From that description you get a complete API gateway architecture diagram showing the NLB, Kong, Auth0, Redis, and all three upstream services with their protocols. Use chat to refine — add a canary routing rule, a developer portal, or a partner API tier.

API gateway diagrams we support

Kong, Traefik, and Nginx gateway architectures
Self-hosted gateway deployments with plugin chains, upstream service routing, TLS termination, and observability integrations.
AWS API Gateway and Lambda integrations
Managed API Gateway setups with Cognito authorizers, Lambda proxy integrations, VPC Link to ECS services, CloudFront caching, and WAF protection.
Backend-for-Frontend (BFF) pattern
