To self-host Hermes Agent on blitz.cloud, install it from the App Store: pick Hermes Agent, choose an address and click Put it online. blitz.cloud sets the address, gives it 1 GB of storage and puts it online with HTTPS. No database needed. It is free to run. On the free plan Hermes Agent sleeps after 30 minutes without a visit, and while it sleeps it stops answering your chat apps and stops running its scheduled tasks. On Pro you can keep it awake, so it answers around the clock.

## Install it

1. In the [dashboard](https://dashboard.blitz.cloud/), open the App Store and pick Hermes Agent, or click Host something new and choose "A ready-made app".
2. Give it an address such as `hermes` and click Put it online.
3. Open the app's Environment tab and find `API_SERVER_KEY`. blitz.cloud generates this key for you; it is what every request to the agent must send.

## Connect it to a model

Hermes Agent runs no AI model itself. Add your model provider's API key in Environment, for example `OPENROUTER_API_KEY`, then point an OpenAI-compatible app or script at `https://hermes.yourname.blitz.cloud/v1` and send the `API_SERVER_KEY` value as its API key. From there it looks like any OpenAI-style endpoint to the app on the other end.

## What it doesn't give you here

Hermes Agent also ships a dashboard and a terminal chat, but both need to run as the machine's owner, and apps on blitz.cloud never do. So on blitz.cloud, Hermes Agent is the API only: no web dashboard, no built-in chat window. If you want to talk to it directly, point a chat client that speaks the OpenAI API at it.

## Keep it answering: the Pro case

On the free plan, Hermes Agent sleeps after 30 minutes without a visit, and a sleeping agent doesn't answer your apps or run its scheduled tasks. On Pro (7 EUR/month), turn on keep-awake in Settings and it stays up, so your own tools can call it any time and its scheduled tasks run on time.

## Size

Hermes Agent runs in the medium resource size: 256 MB reserved from your plan's 512 MB, with room to grow to 1 GB. Measured idle use was under 256 MB with no restarts.
