Cascade is completely free for personal use, including in a commercial environment. That is, you may install any or all of the Cascade components on as many computers as you want, and you may use it for as long as you want, as long as only a single person uses the software or accesses any of the servers. The software you can download from this site is fully functional and is not crippled in any way.
In multi-user environments, you will need to obtain license keys to use Cascade. Each Cascade license key allows one user to install and use Cascade on an unlimited number of PCs. To get you started, we will issue you as many free 90-day trial license keys as you need to set up and evaluate Cascade.
After your 90-day free trial, you will need to obtain paid license keys to continue using Cascade. Please contact us to obtain a price quote for your organization. We don’t believe that a “one size fits all” solution is appropriate for everyone, and we are happy to work with you to better understand your organization’s requirements, including on-site installation help and training, support, custom scripting, new features/add-ons, integration with other software, or a source code license.
