## What it is
A tiny Go web server that echoes back OS information and details of the incoming HTTP request. It is commonly used as a lightweight test backend for proxies, load balancers, and container orchestration setups.

## Use cases
- test backend for reverse proxy or ingress configuration
- debug what headers and IP addresses reach my server
- load testing target endpoint
- health check endpoint for kubernetes probes
- websocket echo server for testing
- generate responses of a specific size for benchmarking

## When to choose
- you need a minimal HTTP echo server in Docker for testing proxies or load balancers
- you want to inspect request headers, TLS, and network info
- you need controllable latency or response sizes for benchmarking

## When to avoid
- you need a production web server or application framework
- you need persistent state or real business logic
- you want a full mock API with configurable routes and payloads

## Facets
- artifact type: service
- maturity: stable
- function: http-server, testing, developer-tools
- domain: developer-tools, networking
- platform: go, cross-platform, cli
- tags: debugging, echo-server, test-server, load-testing, kubernetes, http-debugging, devops, containers, docker, linux
