Can I host my own website files or a custom coded app on Votel?

Yes, depending on the type of site.

Static website: upload your own files. You have full, raw access to the files on your website, so you can upload or download any of them. You can work with the files over FTP, through the Votel MCP or through the API.

Dynamic website or custom app (custom code and its own database, similar to what you build in Lovable): use the built-in app builder, which hosts your app. Give it your code as a ZIP file or paste it, and ask it to set it up, or tell it to build an app that uses your own APIs.

If your site calls a third party API you do not own or control, an imported site can keep using it the same way it does now.

If your site is published somewhere else, you can still embed Votel forms and calendars on it.
