Obsidian[5][6][7]
Best for
Individuals who want notes as plain files on their own device and are comfortable assembling structure themselves.
What you give up
- No built-in shared workspace with page permissions like Notion; collaboration needs the paid Sync shared-vault feature.
- Notion databases only survive well through the API importer, which turns them into Obsidian Bases and imports only the primary view.
Pricing and limits
App free including commercial use per its pricing page; Sync $4 per user per month billed annually or $5 monthly; Publish $8 per site per month annual.[5]
Restrictions that change the answer
- A $50 per user per year commercial licence is offered but described as optional support.
Moving from Notion
Use the Importer plugin. The API route keeps databases as Bases but needs internet and is slow on large workspaces; the zip route works offline but does not keep databases. The Obsidian page says to export HTML, not Markdown, for the zip route.[6]
