The Always-On Assistant: Running Hermes 24/7 on a VPS
Let’s be honest: running an AI agent on your laptop is fun for experiments, but it’s not how you build a real workflow. The moment you close your laptop, the agent dies. The moment your home internet blips, your agent goes dark.
If you want a digital employee that works for you 24/7—summarizing emails overnight, monitoring system logs, or managing a sales pipeline while you’re asleep—you need a VPS (Virtual Private Server).
Self-hosting Hermes AI on a VPS turns your experiment into a piece of infrastructure. It’s always online, it’s secure, and it’s completely under your control. Here’s how to do it right.
Why 24/7 VPS Hosting is the “Grown-Up” Way
You have three main options for running your Hermes Agent:
| Option | Availability | Maintenance Effort | Best For |
|---|---|---|---|
| Local Laptop | Intermittent | Low | Experiments, privacy |
| Managed Hosting | 24/7 | Very Low | Teams, speed-to-deploy |
| Self-Hosted VPS | 24/7 | Medium | Production workflows, total control |
Running on a VPS hits that “sweet spot” for many builders. You get the stability of a 24/7 server without the high cost of a managed service, and you keep total ownership of your agent’s memory, skills, and configuration.
FutureFormDigital Insight
For production-grade autonomy, choose a VPS. While managed hosting like LumaDock is fantastic for getting started quickly, a self-hosted VPS gives you the root-level control you need to harden security, manage local tools, and integrate directly with your other server-based workflows. If you’re serious about building resilient automation, the learning curve of a VPS is a worthy investment.
The Resilient Deployment Strategy
To run Hermes 24/7, you don’t just “start it.” You build it as a service.
1. Provisioning
Grab a VPS with at least 1 vCPU and 2GB RAM (Ubuntu 24.04 recommended). Don’t run as root! Create a dedicated user for your agent.
2. The Headless Install
Use the official installer, then configure your provider (Nous Portal, DeepSeek, OpenRouter, etc.).

A simple hermes gateway command will die the moment you close your SSH session. Use systemd to keep it running forever. Create a service file (/etc/systemd/system/hermes-gateway.service) and enable it:
[Unit]
Description=Hermes Gateway Service
After=network.target
[Service]
User=hermes
WorkingDirectory=/home/hermes
ExecStart=/home/hermes/.local/bin/hermes gateway
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.targetWith this, your agent starts on boot, restarts on crashes, and runs silently in the background.
Frequently Asked Questions (FAQ)
- Q: Do I need a powerful VPS?
- A: No. A small VPS with 1-2 vCPUs and 2GB RAM is sufficient for an agent relying on cloud LLM APIs.
- Q: Is self-hosting on a VPS secure?
- A: Yes, if you harden it. Use firewall rules, SSH keys, non-root users, and don’t expose your agent port publicly.
- Q: How do I access the dashboard securely?
- A: Use an SSH tunnel (
ssh -L) or a private network mesh like Tailscale. Never expose your agent to the public internet.
- A: Use an SSH tunnel (
- Q: What if the server reboots?
- A: If you set up a
systemdservice, it will restart automatically upon boot.
- A: If you set up a
- Q: How much does a VPS cost?
- A: Most basic VPS plans start around $5-$10/month.
- Q: Can I run local AI models (like Ollama) on the VPS?
- A: Yes, but you’ll need a larger VPS with more RAM (8GB+) and likely a dedicated GPU, which increases the monthly cost significantly.
- Q: Is maintenance hard?
- A: You are responsible for OS updates, backups, and monitoring. It’s manageable if you are comfortable with basic Linux admin.
- Q: What happens if the agent hits an API rate limit?
- A: It will fail that task. Configure provider fallbacks and monitor your API usage to avoid disruptions.
- Q: How do I back up my agent?
- A: Regularly back up the entire
~/.hermes/directory. This contains your configuration, memory, and skills.
- A: Regularly back up the entire
- Q: Is this for beginners?
- A: It’s for ambitious beginners. If you know how to SSH and edit a text file, you can do this.
Conclusion
Running Hermes 24/7 on a VPS is the threshold where your AI stops being a toy and starts being an asset. It’s the infrastructure of a modern, resilient, independent digital workflow.
Are you currently running your agent on a local machine, or have you already made the leap to a VPS for true 24/7 autonomy? If you’re hosting, what’s your top tip for keeping it stable? Let’s discuss in the comments!
