go-httpbin, a fast, self contained HTTP request and response testing service for exercising and debugging any HTTP client, proxy, or CI pipeline.
go-httpbin is a dependency free implementation of the well known httpbin, a HTTP request and response testing service. It exposes a rich set of endpoints for exercising anything that speaks HTTP: echo endpoints that reflect a request's method, headers, arguments, and body back as JSON, status code endpoints that return any HTTP status you ask for, and utility endpoints for headers, client IP, redirects, delays, streaming, compressed responses, cookies, UUIDs, and random bytes. It is the predictable, controllable server you point your HTTP clients, SDKs, proxies, API gateways, load balancers, and CI pipelines at when you need to verify how they handle a 429, a slow response, a redirect chain, or a chunked stream. Because it is a single self contained binary it starts instantly, uses very little memory, and needs nothing configured to get going.
The cloudimg image is hardened and fully patched with go-httpbin preconfigured behind nginx TLS, the service bound to loopback and fronted by HTTP basic auth so its redirect and fetch endpoints can never be abused as an open reflector. It ships secure by default with no shared credentials: on first boot every instance generates its own basic authentication password and its own TLS certificate and writes the per instance credentials to a root only file. Every instance is backed by a paired deploy guide and 24/7 cloudimg support.
