Hermes Agent

Self-hosted open-source autonomous agent with persistent memory and multi-platform messaging

Notes

Free and open-source under the MIT license, built by Nous Research. Self-hosted on your own infrastructure, from a small VPS to serverless cloud. Includes persistent cross-session memory, an autonomous skill-creation system, scheduled automations, parallel subagents, sandbox environments (Docker, SSH, Modal, and more), and multi-platform messaging across Telegram, Discord, Slack, WhatsApp, Signal, Email, and CLI. Model provider is user-chosen, so model usage costs depend on whichever provider you connect.
