Hermes Agent
Open-source AI agent with persistent memory and a messaging gateway
What is Hermes Agent?
Hermes Agent is an open-source autonomous agent from Nous Research that runs on your own computer, on a server or in the company's hosted cloud. It keeps memory between sessions, writes its own reusable skills, runs scheduled jobs, and is reached from a terminal, a desktop app or messaging platforms such as Telegram, Discord, Slack and WhatsApp. The software is MIT licensed and free; model access comes from any provider you connect or from Nous Portal, an optional credit subscription.
Hermes Agent has a free plan. Paid plans start at $20 per month for the optional Nous Portal Plus tier; the agent is free. See every plan
Good for
- Developers who want an agent on their own machine, server or VPS
- Reaching one agent from Telegram, Discord, Slack or WhatsApp
- Unattended scheduled jobs such as reports and briefings
Worth knowing
- The agent is free, but paid models cost extra: your own provider's rates, or Nous Portal tiers from $20 a month.
- Desktop apps are offered for macOS and Windows; on Linux the install is through the terminal.
- The platform support page lists no iOS version, and Android runs only through a prerelease Termux package.
- Hermes Cloud needs $2 of Nous credit or an active subscription to deploy, and bills inference separately from the instance.
Key features
- Messaging gateway
- One gateway connects the agent to Telegram, Discord, Slack, WhatsApp, Signal, Matrix, email, Microsoft Teams and other platforms, more than 20 in all, sharing a single memory.
- Memory and self-written skills
- The agent keeps memory across sessions, creates reusable skills from work it has done and revises them in use. Skills follow the open agentskills.io format.
- Scheduled automations
- Built-in cron accepts natural-language schedules for reports, backups and briefings and delivers the results to any connected platform.
- Subagents
- Isolated subagents with their own conversations and terminals handle parallel workstreams without filling the main agent's context.
- Terminal backends and sandboxing
- Commands run locally or in Docker, over SSH, or on Daytona, Singularity, Modal or Vercel Sandbox, with command approval and container isolation.
- Nous Portal and Hermes Cloud
- A Portal subscription supplies credits for 200+ models and hosted web search, image generation, text-to-speech and browser tools. Hermes Cloud hosts an always-on agent, billed daily.
