Why Self-Host Instead of Stack Overflow?

  • Data ownership. Your data stays on your server, not on Stack Overflow’s infrastructure.
  • Predictable costs. Pay a fixed VPS cost instead of growing per-user or per-usage fees.
  • No vendor lock-in. Export and migrate your data anytime. You control the database.
  • GDPR and compliance. Hosting your own tools simplifies data residency and compliance requirements.
