• RedLine13

    RedLine13 is focused on bringing (Almost) Free Load Testing to the Cloud. We were inspired by the high price of load testing tools, or the lack of cloud-readiness of the free tools for load testing.

Write Tests in JMeter, Gatling, PHP,or NodeJS

We provide a free service that helps you setup and deploy load testing instances in your Amazon account. You have to pay for the load testing part of this on the spot instances - hence the (Almost). As an example: if you want to run a load test with 200 m1.small Load Agent Servers hitting your application or site, we can manage them as spot instances and it will cost you about $2.00 for an hour. That should give you enough horsepower to emulate 50,000 users continuously providing load. And we provide you with some pretty real time graphs and reports when you are done (and that part is free).


Simple Trail Map

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 10,000s of thousands of users within a few minutes.


JMeter Trail Map

The Apache JMeter™ application is open source software, a 100% pure Java application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions.

Gatling + Redline13 Integration

Gatling Trail Map

Gatling.io is an open-source load testing framework based on Scala, Akka and Netty. High performance Ready-to-present HTML reports Scenario recorder and developer-friendly DSL


Custom Test Trail Map

Custom load tests give you the flexibility of writing load tests in languages and utilities you use every day.  You can write custom tests in either PHP or Node.js.

The Background

This is an endeavor by Stephen Sigwart, Bob Bickel and Richard Friedman. We developed this as part of our scalability efforts on RunSignUp. We thought it was so cool, we should share it with others. But feel free to use it for free on our site and provide us feedback so we can work on making it better in our off hours ;-)

Continuously Integrating


Continuous Integration (CI) is a development practice that requires a team to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early. With services such as RedLine13 it is now cost-effective and easy to integrate load testing into this lifecycle.

Continuously Testing


We are excited to announce or partnership and integration with UBIKLoadPack. Customers of both platforms now have a simple way to launch tests for HTTP Live Video Streams, GWT Applications, Flex/Adobe Air Apps
