API performance testing
Simulate real-world traffic and measure your APIs' performance with Postman's new performance-testing features.
Simulate real-world traffic
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.
