There's a lot more to it--this is just a tiny part we're giving away, not something we'll make money on.
We do real-browser load testing in the cloud using the same scripts folks use for integration testing. Because they can also run locally, you can run them alongside your integration tests with each commit, and you always know you have working scripts. Scripts are easy to code and maintain because they can use page objects like functional tests.
This means you can have versioned load test/monitoring scripts in your project that always work with a particular sha. When you deploy, you can start transactional monitoring immediately. It also means load testing is not a separate stage in your development lifecycle.
