“Hermes Agent backend” means two things. First, the terminal backend — where Hermes actually runs commands, from your own machine to Docker, SSH or a cloud sandbox. Second, hermes serve, the API backend the desktop app and dashboard connect to. In the video below I run Hermes in the cloud for free. Here’s how both kinds of backend work and which to choose.
Key takeaways
- Hermes supports 7 terminal backends: Local, Docker, SSH, Daytona, Modal, Vercel Sandbox and Singularity.
- Docker is the safest choice for risky commands.
- SSH lets Hermes work on a remote server.
hermes serveis the API backend for the desktop app and dashboard.
Hermes Agent terminal backends
| Terminal backend | Where commands run | Best for |
|---|---|---|
| Local | Your own machine | Everyday use |
| Docker | A container | Sandboxing anything risky |
| SSH | A remote server | Running on a VPS or another computer |
| Daytona | A cloud dev environment | Disposable cloud workspaces |
| Modal | Serverless cloud | Burst compute |
| Vercel Sandbox | Vercel’s sandbox | Isolated cloud execution |
| Singularity | HPC containers | Research and university clusters |
Which Hermes Agent backend should you use?
Start with Local if you’re just trying Hermes on your own machine. Switch to Docker as soon as Hermes is running commands you haven’t reviewed — a mistake in a container can’t touch the rest of your system. Use SSH when you want Hermes to work on a VPS or another computer. The cloud sandboxes — Daytona, Modal and Vercel Sandbox — are great for disposable environments and burst work.

The hermes serve API backend
The desktop app and the web dashboard don’t run the agent themselves — they talk to an API backend, hermes serve. On a headless server you can run the backend there and connect a desktop or dashboard to it remotely. It’s separate from the gateway (which runs messaging and cron in the background), but both share the same Hermes home folder.
Running a remote Hermes backend
- Install Hermes on the server with the official script.
- Run the backend and the gateway on the server.
- Reach it securely — Tailscale is the simplest way, instead of opening ports.
- Connect your desktop app or dashboard to it.
That way your agent, memory and jobs live on the server, and your laptop is just a window into it.
Model backends are separate
The terminal backend decides where commands run; the model provider decides which AI does the thinking. You can mix them freely — for example Docker for commands, with Claude on AWS Bedrock or a free Nous Portal model for thinking.
Backend security tips
- Use Docker or a cloud sandbox for untrusted commands.
- Give SSH access to a dedicated user, not root.
- Never expose the API backend to the open internet — use Tailscale.
- Keep approvals on for anything that deletes or sends.
- Update Hermes regularly with
hermes update.
The bottom line on Hermes Agent backend
Choose your Hermes Agent backend by risk and location: Local to start, Docker for safety, SSH or a cloud sandbox for remote work, and hermes serve when you want your desktop app to drive Hermes on a server.
FAQ: hermes agent backend
What is a Hermes Agent backend?
Either the terminal backend where Hermes runs commands, or the hermes serve API backend used by the desktop app and dashboard.
What terminal backends does Hermes support?
Local, Docker, SSH, Daytona, Modal, Vercel Sandbox and Singularity.
What is the safest Hermes backend?
Docker or a cloud sandbox, because commands run in isolation.
Can Hermes run commands on a remote server?
Yes — with the SSH backend.
What is hermes serve?
The API backend that Hermes Desktop and the dashboard connect to.
