# Scalability Testing

**Canonical:** https://apis.io/providers/scalability-testing/  
**Website:** https://k6.io/  
**APIs profiled:** 6

A collection of tools, frameworks, APIs, and datasets for performing scalability and load testing of web services, APIs, and distributed systems. Scalability testing evaluates how a system performs as load increases, identifying bottlenecks, capacity limits, and performance degradation points. Key tools include Apache JMeter, k6, Gatling, Locust, and cloud-based platforms like AWS Load Testing, Azure Load Testing, and BlazeMeter.
