How to self-host your Notion alternative
Self-hosting your Notion alternative means your notes, wikis and Notion-style databases live on your own server, not in Notion's cloud — no free-tier block limit, no risk of a price hike affecting you.

Real server requirements
Between 1GB and 2GB of RAM depending on the tool — never a single number.
All 5 catalog alternatives ship a docker-compose.yml and need between 1GB and 2GB of RAM (AppFlowy and Huly are the lightest; Outline, Docmost and AFFiNE need more for their built-in search/whiteboard engine). Updating is a docker compose pull && docker compose up -d — back up the data volume first, same as any database.
Migrating from Notion depends on which alternative you pick: each one imports different formats (Markdown, HTML, CSV) with varying fidelity for databases, page relations and embedded blocks — check the alternative's own import documentation before assuming your whole workspace will carry over untouched. None of them guarantees an automatic 1:1 migration. Before migrating, export a full backup directly from Notion (Settings → Export all workspace content) and keep it separately, regardless of how the import goes.
What you gain and lose versus the SaaS
You won't get Notion's polished real-time collaboration without extra infrastructure work (websockets, CDN), and maintenance (backups, updates) becomes yours. In exchange, your notes don't depend on Notion staying in business, raising prices, or changing its free-tier limits.
