Open Architecture for Building and Running Load Tests. Need to quickly load test a home page, a single URL within your site, or even a mobile API endpoint. We allow you to compose simple tests and then scale them to tens of thousands of users within a few minutes. Apache JMeter, Gatling, Selenium, and WebDriver are more than just open source tools we enable in cloud load testing, they are vibrant communities with deep knowledge and products built on what real users need. Open load tests give you the flexibility of writing load tests in languages and utilities you use every day. You can write custom tests in Python, PHP or Node.js. We provide an open, easy, and cheap way for load testing. We achieve this with an open architecture which provides tuning and control to setting up the cloud load agents.

The ReadyAPI platform accelerates functional, security, and load testing of RESTful, SOAP, GraphQL and other web services right inside your CI/CD pipeline. ReadyAPI allows teams to create, manage, and execute automated functional, security, and performance tests in one centralized interface - accelerating API quality for Agile and DevOps software teams. Teams can get started by importing API definitions like OAS (Swagger) or WSDLs, testing and recording live API traffic, or virtualizing web services to remove pipeline dependencies. Create comprehensive, data-driven functional API tests without the hassle of maintaining scripts. Generate load, stress, and spike tests to validate whether your API can handle real-world traffic conditions. Secure your vulnerable APIs from XSS, malformed XML, SQL injections and more with each deployment. Remove dependencies in your testing pipeline by virtualizing RESTful, SOAP, TCP, JMS, and other web services.

Save about 50 to 70% of your time using OctoPerf instead of Apache JMeter™ for the Thread Groups creation (aka Virtual Users). Scale up to one million users on our Cloud load testing infrastructure.
