Why Teams Switch from Notion to Open Source
Proprietary SaaS platforms often lock your data behind rigid APIs, increase renewal costs year-over-year, and restrict enterprise customization. By contrast, open-source alternatives offer:
Full Data Sovereignty
Your customer data never leaves your VPC. Run database migrations, run local backups, and comply with GDPR/HIPAA without enterprise tier upsells.
Predictable Economics
Pay for raw cloud compute (e.g. AWS or Hetzner VPS) rather than paying $20 to $50 per user seat every single month as your headcount expands.
Custom Integrations
Audit the source code, build custom plugins, and write webhooks directly into internal company services without artificial rate limits.
Zero Vendor Risk
No sudden pricing model changes, feature deprecations, or sudden API shutdowns. Your software operates independently forever.
