A Notion replacement must preserve more than documents. Inventory databases, relations, permissions, comments, embeds, automations and API integrations before deciding whether a local-first, self-hosted or managed workspace is suitable.
Export representative workspaces first. Import the same documents, structured data and attachments into each candidate, then test collaboration, search, permission boundaries and a second export.
Use the profile fields below as a starting point, then confirm current capabilities, migration paths, licensing and pricing in the official documentation.
