Run your AI agents 24/7 on a VPS. Server setup, installation, security hardening, and monitoring.
AI agents need to run continuously — morning briefings, scheduled tasks, monitoring, and responding to messages at any hour. A VPS gives you 24/7 availability, persistent sessions, and full control over your infrastructure. Recommended specs: 2+ vCPU, 4GB RAM, 40GB SSD.
Hetzner (best value, from 4 euros per month), DigitalOcean (developer-friendly, from 6 dollars per month), and Linode (reliable, from 5 dollars per month). All three offer one-click Node.js images that simplify setup.
SSH into your server, create a non-root user, set up SSH key authentication, configure the firewall (UFW), install Node.js 20+, and install Claude Code. Use systemd or pm2 to run your agent as a background service that auto-restarts on crash.
Disable password authentication (SSH keys only). Enable automatic security updates. Configure fail2ban to block brute force attempts. Use environment variables for all secrets — never commit API keys to code. Set up log rotation to prevent disk fill.
