As we don't want this to turn into a DDoS-on-demand tool, this online version of Goad is intentionally limited. The CLI version of Goad is more fully featured and can do up to 100,000 requests per second.

Sites with active DDoS protection or redirects (such as google.com) are known to not work properly

How Goad works

Goad takes full advantage of the power of Amazon Lambdas for distributed load testing. You can use goad to launch HTTP loads from up to four AWS regions at once. Each lambda can handle hundreds of concurrent connections, we estimate that Goad should be able to achieve peak loads of up to 100,000 concurrent requests.
