Open-Source & Self-Hosted Alternatives to Notion & Confluence
All-in-one workspace and wiki that traps company intellectual property in proprietary cloud silos.
Why Migrate Away from Notion & Confluence?
Notion stores company internal documentation, architecture specs, and credentials on closed US servers with no end-to-end encryption. Performance degrades on large workspaces, offline editing is notoriously poor, and seat licensing adds up quickly. Self-hosted wikis give your team full markdown ownership, local speed, and total data privacy.
