Leywn 1.0.0 released — the last echo service you will need

Fri, 31 Jul 2026 00:00:00 +0000

Leywn (“Last Echo You Will Need”) reaches 1.0.0 today. It is a modern, all-in-one demo and test backend for APIs and HTTP services: a single container that mirrors requests, speaks every common authentication scheme, returns any HTTP status code, injects faults on demand, generates test data, and serves its own Swagger UI — so you can test clients, proxies, load balancers and API gateways without standing up a real backend.
