We have a demonstration login available for a basic version of Steller CMS. Go ahead and try it out. The site resets every hour (EST), so be aware that you will lose your changes.
Front end demo: http://demo.stellercms.com/
Admin Login Demo: http://demo.stellercms.com/administrator/
Please note that this is a basic installation. If you would like to see the functionality of one of the various components that we offer, we can set up a special demo.
If you have any questions, please feel free to contact us.
