What is Echo Server?

An echo server replicates the request sent by the client and sends it back, making it perfect for:

  • Testing and debugging HTTP requests
  • Development and integration testing
  • Learning about HTTP protocols
  • Mock server for testing

Features

  • ✅ All HTTP Methods - GET, POST, PUT, PATCH, DELETE
  • ✅ Request Details - Query parameters, body, IPs, host, URLs
  • ✅ Custom Headers - Request headers and custom response headers (supports duplicates)
  • ✅ Environment Variables - Access to server environment
  • ✅ Control via Headers/Query - Custom responses, status codes, delays
  • ✅ File Operations - Directory listing and file reading
  • ✅ Health Checks - Built-in monitoring and structured logging
  • ✅ Production Ready - Docker, Docker Compose, and Kubernetes support

Quick Example

# Start the server
docker run -p 80:80 echoserver:latest

# Test it
curl http://localhost:80

# Custom response
curl http://localhost:80/?echo_code=404&echo_body=Not+Found
