For business reasons, I’ve been taking a look at various efforts to support multiplayer Obsidian. The company only offers Obsidian Publish, which as the name suggests is really more oriented toward publishing than multiplayer editing, commenting, and sharing. Even when touting its collaborative features, it’s pitched as a way to collaborate on publishing. Other publishing options — like Blot — can publish, but don’t support collaborative editing.
Others I (re)looked at recently:
Relayseems to have an active user base, and adding features quickly, and has implemented Universal File Sync — enables syncing images, videos, audio, pdfs, and more — but I’ll have to upgrade to a paid plan. I will write it up once I’ve upgraded. Requires your collaborators run their own Obsidian instances.Relay’s the alternative I am watching most closely.Screen Gardenseems to be coming along too, but also lacks coherency. If I can include an image in the shared folder, how come I can't reference the image to see it embedded in another?Share Noteis just a means to publish, but in high fidelity, using your own plugins. In my case, that includes all thethe Tufte sidenotescss from TfTHacker. I use this frequently to share well-formatted but read-only docs with others.
Each of these could have their own review, but I am in a hurry, and none of them meet my needs, yet.
