Self-Hosting Economics & TCO Methodology FAQ

How is the SaaS vs Self-Hosted Total Cost of Ownership (TCO) calculated?

We multiply published per-user monthly SaaS pricing (e.g., Slack Pro at $8.75/seat, Notion Plus at $10/seat, Jira Standard at $8.15/seat) by your team size over 12 months, and subtract the flat cost of a dedicated cloud VPS ($12–$28/month on Hetzner, DigitalOcean, or AWS Lightsail) capable of running the equivalent Docker containers.

Does self-hosting open-source software require a dedicated DevOps team?

For small-to-midsize teams (5–100 seats), modern Docker Compose stacks with automated volume backups and Watchtower/Coolify container updates require less than 1–2 hours of maintenance per month.

Can a single VPS run multiple open-source SaaS replacements simultaneously?

Yes. A single 4 vCPU / 8GB RAM NVMe Linux instance (~$16/month) can comfortably co-host Plausible Analytics, Vaultwarden, Outline Wiki, and Uptime Kuma behind a Caddy or Traefik reverse proxy.
