What costs are NOT in the table
The plan prices above only cover the VPS rental. A few extra costs to keep in mind for any honest self-hosting budget:
- Domain name: $8-15/year for a .com (Cloudflare or Porkbun, sold at-cost).
- Backups: $2-5/mo for offsite backup storage (Backblaze B2, Hetzner Storage Box).
- SSL/TLS: $0 if you use Caddy or Traefik (Let's Encrypt is free).
- Email-out: $0-15/mo if WeKan ® - Open Source kanban sends notifications. Postmark, SendGrid free tiers suffice for <100 emails/day.
- Your time: 1-3 hours initial setup, ~30 min/month maintenance once stable. The biggest line item if you bill by the hour.
