API Gateway Simulator — Interactive System Design Lab
Route requests through an API gateway and observe how authentication, rate limiting, and path-based routing work together as a pipeline. Fire requests with missing tokens, exceed rate limits, and watch exactly where each request is rejected — and why gateways are the standard entry point for microservice architectures.
Route requests through a gateway and watch authentication, rate limiting, and routing enforce policy in sequence.
This free interactive simulation runs directly in your browser — no account needed. Adjust the parameters and watch how the system responds in real time.
