To stress test APIs, you can use tools like:
- k6 — great for modern load testing, scriptable in JavaScript, easy CI/CD integration
- Apache JMeter — classic, feature-rich, GUI-based
- Locust — Python-based, flexible for custom user behavior
- Artillery — simple, good for API/load testing with YAML/JS
- Gatling — high-performance, JVM-based, strong reporting
- wrk / wrk2 — lightweight, fast HTTP benchmarking tools
- Postman/Newman — okay for functional runs, but not ideal for real stress testing
If you want to stress test APIs specifically, I’d usually recommend:
- k6 if you want something modern and code-driven
- Locust if you prefer Python
- JMeter if you want a GUI and lots of built-in options
A good stress test plan usually includes:
- ramping up concurrent users
- sustained load
- spike tests
- measuring latency, error rates, throughput, and resource usage
If you want, I can recommend the best tool based on your stack (Node, Python, Java, etc.) or help you write a sample test script.
