I just wanted to ask the community for advice and/or suggestions for the smartest method to turn my editor from stand-alone on a local computer to cloud-based multi-user collaborative. My implementation is pure Prose Mirror and vanilla JS, as such I do not use commercial solutions like TipTap where they have a solution they built for their paid service.
Are there other open source or even commercial collaborative add-ons for PM that are out there, so I would not have to reinvent the wheel for this use case?
