The short answer is “Yes” … we’ve always provided a SaaS version of our product. However, we have not yet supported using it with Confluence (either your own or hosted).
We expect to provide this service for production use with V4.1.3 of frevvo, which will be released around the end of February. You can try it out right now at no cost on a test server (obviously, that helps us as well). If you’re interested in doing that, please contact us.
