Notion is a popular all-in-one workspace for docs, wikis, and databases, but it's closed-source, cloud-only, and your data lives on Notion's servers — there's no self-hosted option, and larger teams eventually hit its paid-seat pricing.

If you want a close match to Notion's docs-plus-database workspace that you can self-host, AppFlowy is the most direct alternative. If what you actually use Notion for is its database/table views rather than its documents, Baserow and NocoDB are purpose-built, spreadsheet-style database tools worth considering instead.
