Notion charges $10-25 per user per month and stores your team's most sensitive notes on its servers. The 12 best open-source self-hosted alternatives give you unlimited users, full data ownership, and GDPR-ready hosting for $11 per month.
On-Premise
Context
Three reasons drive the migration to self-hosted alternatives.
$10/user/mo Personal Pro, $15 Plus, $25 Business. For a 50-person team that's $12,000-15,000 per year.
Sensitive product specs, customer info, financial planning all live on Notion's servers. GDPR / SOC 2 concerns for regulated teams.
Notion's database structure, formulas, and synced blocks make migration painful. Open alternatives use standard formats.
