Postman can simulate multiple, parallel users—or "virtual users"—that send requests to your APIs continuously for a specified duration. This lets you observe and test the performance of your APIs in real-world scenarios.

Deploy with confidence

With Postman API performance testing, you can easily observe performance metrics such as response times, error rates, and requests per second under a simulated load. This helps you identify performance bottlenecks early, improve performance, and deploy to users with confidence.

Postman v11 is here!

It's jam-packed with updates to help you collaborate on your APIs, augment yourself with AI, and more.
