Running Multiple Apps Together

Most of these apps can run on a single well-provisioned VPS using Docker Compose. For example, a Cloud VPS with 8GB RAM and 4 vCPUs can comfortably run Open WebUI, n8n, Uptime Kuma, Vaultwarden, and Plausible simultaneously.

Use Nginx or Traefik as a reverse proxy to give each app its own subdomain with automatic SSL from Let’s Encrypt.

What You’ll Need

A Cloud VPS from Canadian Web Hosting gives you the foundation to run all these apps:

  • Full root access — install anything you need
  • Canadian data centres — Vancouver and Toronto for data sovereignty
  • 24/7 support — real humans who can help troubleshoot
  • Scalable resources — add RAM or CPU as your needs grow
  • SSD storage — fast performance for databases and files

Start with a 4GB Cloud VPS for lighter apps (Uptime Kuma, Vaultwarden, Plausible), or go with 8GB+ if you want to run AI tools like Open WebUI or OpenClaw.

Why Self-Host in 2026?

  • Data ownership — your files, photos, and conversations stay yours
  • Cost savings — one VPS costs less than multiple SaaS subscriptions
  • Privacy — no tracking, no data mining, no ads
  • Learning — hands-on experience with Docker, Linux, networking
  • Resilience — your tools work even when SaaS providers have outages
