Open source under MIT

Read, audit and extend the full agent source.

Self-hosted AI agent

Runs as a process on your own machine.

One command to install

macOS, Windows and Linux install from the shell.

Your model provider

Point the agent at the provider you configure.

A self-hosted AI assistant you control

You decide where it runs, what it can reach and what happens to its files. It answers to you, not to a vendor.

#1 Open source

Open source under MIT

Free to run, study, modify and redistribute. An open source AI agent platform you can read and audit.

#2 Run it

Your machine or your server

Runs as a process on hardware you choose. You start it, stop it, upgrade it and inspect what it did.

#3 Control

Your runtime and data directory

Conversations, memories and skills are stored in your Hermes data directory. Back it up when you migrate machines.

#4 Models

Bring your own provider

Model requests go to the provider you configure — your own account, or a catalog of models through Nous Portal.

#5 Memory

Memory and skills

The agent saves useful details and writes reusable skills from finished tasks. Review what it keeps.

#6 Portal

Optional Nous Portal

Add one account for a catalog of models and hosted tools, or an always-on cloud agent when you want one.

Install the self-hosted AI agent

Three ways to run it: from the terminal, from the Hermes Desktop app, or as a hosted cloud agent in Nous Portal.

  1. One command in the terminal

    macOS, Windows and Linux install from the shell. No sign-up required to run the base agent.

  2. Hermes Desktop

    The same open-source agent with a graphical interface; see the download page for packages and requirements.

  3. Or one-click cloud

    Deploy a hosted agent in Nous Portal for work that continues with your computer off.

Hermes Desktop app with an agent list, a chat conversation and inline tool cards
Hermes Desktop: the same open source agent with a graphical interface, running on your own machine.
