The Selenium Nodes can be used free of charge during a one month evaluation period. After that, licenses are available for an annual fee — they include fast lane support and all updates. Even better: Your payment allows us to stay on par with recent technology updates, provide you with technical support and to continue implementing new and awesome features from our growing backlog.
Licenses are per user. This means, every person within a company using the software requires one license. Check out all the licensing terms and conditions here. In case you have questions, special licensing requirements or any other doubts, please check the FAQs (#q18, #q29, #q30) and do not hesitate and get in touch if you have questions not covered there!
