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.

Diagnose web UI and API performance issues with data that’s highly actionable and extremely accurate. Traditional performance testing has always happened in the protocol layer. This results in massive tests that are hard to read, require extensive programming, and take hours, even weeks to set up. Even the results aren’t even indicative of the real world as they test the protocol. No wonder performance testing seemed hard. But it doesn't have to be with LoadNinja. Instead of testing the protocol, test the actual end-user experience across tens of thousands of browsers using our TrueLoad technology, saving you over 60% of effort. No maintenance or setup required to give you the most accurate understanding of performance in the least amount of time possible. Increase test coverage for websites, web apps, and APIs without sacrificing quality. Create complex performance tests without complex correlation.
