Hi Nuria,
Thanks for reaching out! As our plugins are built specifically to work in WordPress environments, we don’t provide support for any type of alternative installation using third-party solutions. If you’d like to maintain a single WordPress install and have your calendar events display on other non-WordPress sites, I’d consider setting up a Google Calendar for creating and displaying your events on your non-WordPress sites, then importing those events to The Events Calendar using Event Aggregator. I’d be glad to answer any questions you might have about this setup or how it might work for you!
Thanks again for stopping by, and let me know if there’s anything else I can assist with! π
