Hi Ellen and thanks so much for getting in touch! I’m stoked that you’re interested in using The Events Calendar. 🙂
We’re WordPress-only at the moment. I have personally worked with the Cascade CMS before, but I’m guessing it would be a heavy lift to integrate the two. I do know that the WordPress REST API is getting very good and could be an option as far as hosting data on a WordPress site, then feeding the content elsewhere. Again, I haven’t tried this personally, but could be worth looking into.
Let me know if you have any other questions here and I’d be happy to help.
My pleasure! Thanks again for reaching out. If you do decide to use the WordPress REST API, please let us know–I’d love to see how that works out. 🙂
