Overview

Siege is an open-source regression test and benchmark utility. It can stress-test a single URL or multiple URLs simultaneously. It allows a user to simulate a configurable number of concurrent users hitting a server, records the response times, and reports statistics at the end of the test. It is a simple, command-line driven tool favored for its ease of use and raw power.

✨ Key Features

  • Command-line interface
  • Support for basic authentication, cookies, and HTTP/HTTPS protocols
  • Configurable number of concurrent users and test duration
  • URL regression testing
  • Simple, concise output statistics

🎯 Key Differentiators

  • Extremely simple to use for basic load testing
  • Ability to test multiple URLs from a file
  • Lightweight and efficient

Unique Value: Siege provides a simple, powerful, and no-nonsense way to put a web server under load directly from the command line.

🎯 Use Cases (4)

Quickly benchmarking a web server Simple API stress testing Validating server performance after configuration changes Regression testing of URLs

✅ Best For

  • Stress testing web server throughput and response times

💡 Check With Vendor

Verify these considerations match your specific requirements:

  • Complex user scenarios with logic and state
  • Testing non-HTTP protocols
  • Users who require a graphical interface

🏆 Alternatives

Apache Bench (ab) wrk
