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.

All-In-One cloud testing platform for load testing and performance testing, website speed testing, website UI testing, mobile applications and API endpoints. Easy upload and run JMeter tests from multiple cloud locations with thousands of users. Inspect real-time performance metrics for your Website and APIs with Apache JMeter from the cloud. Monitor changes over time and get advice on how to reduce page load times. We run your tests from cloud instances at scheduled times and notify you if something goes wrong. Load your websites and web pages in mobile emulators and inspect screenshots to find potential rendering issues, invalid HTML, missing images, wrong CSS. Schedule runs and inspect rendered images on all devices in just seconds. Emulate your site across different screen sizes and resolutions. Generate screenshots of two websites in just seconds and compare the generated screenshots by a threshold to check differences.

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.
