What is Hermes Agent?
Hermes Agent is Nous Research’s open-source, MIT-licensed take on a personal AI agent that doesn’t live on your laptop. Instead of a chat tab you open and close, it’s a process that runs continuously on a server, keeps a persistent memory of what it’s learned about you and your projects, and reaches you wherever you already are — Telegram, Discord, Slack, WhatsApp, Signal, or a plain terminal.
Nous Research describes it as the only agent with a “built-in learning loop” — it creates skills from experience, improves them with use, and builds a deepening model of who you are across sessions, rather than starting from zero every conversation.
Key Features
- Persistent memory — a memory database under
~/.hermes/memory/that survives restarts, so the agent remembers past conversations, projects, and preferences instead of forgetting everything between sessions. - A large bundled skills library — roughly 78 skills ship out of the box, covering GitHub workflows (PR review, issue triage), document handling (PDF, DOCX, XLSX, PowerPoint, Notion), research (arXiv, web search), coding tasks (debugging, TDD, code review), and more. The agent can also author new skills for itself as it solves novel problems.
- Model-agnostic — 300+ models across Nous Portal, OpenAI, Anthropic, OpenRouter, and custom/self-hosted endpoints. Swap providers anytime with
hermes model, no code changes. - Messaging gateways — 20+ documented platforms, including Telegram, Discord, Slack, WhatsApp, Signal, Google Chat, Matrix, MS Teams, LINE, Feishu/Lark, and Home Assistant, so the agent is reachable from your phone, not just an SSH session. See connecting it to Discord for a full setup walkthrough.
- Configurable terminal backends — choose where the agent actually executes shell commands and code: locally, in Docker, over SSH to another machine, or in a serverless sandbox (Modal, Daytona).
- A tool pool — web search & extraction, image generation, text-to-speech, speech-to-text, and browser automation, toggled individually during setup.
- Cron-style scheduling — recurring automated tasks, delivered back to you through whichever messaging platform you’ve connected.
- MCP integration — connects to any Model Context Protocol server for extended capabilities beyond the built-in tool set.
How It’s Installed
Hermes ships a single-command installer for Linux, macOS, and WSL2:
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bashThe script installs its own Python 3.11 runtime, uv, Node.js, ripgrep, and ffmpeg, and drops everything into an isolated location under your home directory — no root access needed. After that, hermes setup walks through picking an LLM provider (Nous Portal’s Quick Setup needs only a device-code login, no API key), a default model, which tools to enable, a terminal backend, and optionally a messaging platform.
For a full walkthrough of running it on a free cloud instance, see How to Deploy Hermes Agent on Oracle Cloud’s Free Tier.
Where It Runs
Because a messaging gateway only stays reachable while its process is alive, Hermes needs somewhere to run continuously — closing your laptop shouldn’t take the agent offline. Common choices:
- A small cloud VPS — including free-tier instances, like Oracle Cloud’s Always Free Arm or Micro shapes.
- A local machine you leave on — a spare desktop, NUC, or Mac mini.
- Serverless sandboxes — Modal or Daytona, where the environment hibernates when idle and wakes on demand.
Whichever you choose, the messaging gateway is typically kept alive with a process supervisor (systemd, for instance) so it survives reboots and restarts automatically if it crashes.
Hermes Agent vs. Other Self-Hosted Agents
Hermes isn’t the only open-source, self-hosted personal-agent project — OpenClaw covers similar ground with a mature plugin ecosystem and a web-based Control UI dashboard. The two overlap enough that the choice mostly comes down to what you value more: Hermes’s learning loop, skills library, and wider messaging-channel list, or OpenClaw’s dashboard and plugin maturity.
