Hermes Agent is an open-source generalist agent harness developed by Nous Research that runs locally or in the cloud. It features persistent memory, dynamic skill creation, isolated sandboxing, and direct integration with chat platforms like Telegram, Discord, and Slack. It works across local desktop environments and terminals to handle coding, research, and scheduled background tasks.

What it's for

  • Run automated background tasks like daily briefings, reports, and backups via natural-language cron scheduling
  • Interact with a persistent personal assistant through Telegram, Discord, Slack, or terminal
  • Execute complex coding, ML workflows, and shell tasks across isolated sandboxes like Docker or SSH
  • Delegate multi-step pipelines to isolated subagents to preserve main context

Features

  • Persistent multi-level memory system retaining context and learned skills across sessions
  • Dynamic skills engine that auto-generates and stores reusable routines
  • Messaging gateway supporting Telegram, Discord, Slack, WhatsApp, Signal, email, and CLI
  • Five execution sandboxing backends: local, Docker, SSH, Singularity, and Modal
  • Browser automation and web search via headless Chromium pool
  • Isolated subagents running independent terminal sessions and Python RPC scripts
  • Available as native desktop apps for macOS and Windows, or via terminal on Linux

Pricing

Open source. Free and open source under MIT; optional Nous Portal subscriptions start at $20/month for hosted tool usage and model credits.
