Obsidian is built on-top of just markdown files, so you can do whatever you want with them. E.g. if you need multiplayer editing you could use 3rd party solutions or even something like HedgeDoc.
Affine is more closer to Notion and self-hostable.
I'm not sure DocMost is a Notion alternative, it's just a note-taking tool without many of the features that give Notion its unique position.
I'm always disappointed by note-taking tools calling themselves a Notion alternative when they do not provide an alternative to Notion and are instead just another note-taking tool with a simple UI.
If you want to be a Notion alternative provide the things that make Notion great, e.g. the database functionality. It's okay to be a simple colaborative notes tool, but that is not a Notion alternative.
Perhaps try it first before dismissing it as just a “note-taking tool,” which it isn’t.
We have support for team-spaces, permissions, diagrams, real-time collaboration, comments, page verification workflows, AI, SSO/LDAP, search, audit logs, API, public sharing, and a lot more.
Btw, we have plans to introduce a database-like feature.
Confluence and Notion are not equivalent products. Docmost looks to be similar to Confluence - a full fat wiki, but the whole point of Notion was its database-like features.
