Hermes Agent

Agent-nativeOpen Source

Open-source autonomous agent platform with memory, skills, subagents, and messaging gateways

Overview

About Hermes Agent

Hermes Agent is an open-source autonomous agent platform from Nous Research for running persistent agents across local and remote environments. It combines long-term memory, reusable skills, tool calling, subagents, and messaging integrations so agents can operate continuously instead of only inside a single chat or terminal session.

Features

Persistent memory and workspace context so agents can carry state across sessions
Reusable skills system for packaging task-specific instructions, scripts, and workflows
Subagents and multiple runtimes for delegating work across different execution environments
Messaging gateway integrations so agents can work through chat surfaces like Slack, Telegram, and other channels
Tooling for browser control, code execution, document analysis, and environment automation

So agents can…

Keep working over time with memory, project context, and recoverable task state
Hand off specialized work to subagents while a main agent coordinates the broader job
Operate through chat, local tooling, and remote environments as part of one continuous workflow

Listing decision

Why Hermes Agent is listed

Hermes is itself the autonomous agent runtime: it maintains memory, invokes tools, learns skills, delegates to subagents, and operates through terminal, desktop, API, editor, and messaging surfaces.

Before you choose

Fit and limitations

Best for

Persistent self-hosted assistants that need reusable skills, tool calling, cross-session memory, subagents, scheduled work, and access from multiple messaging or developer interfaces.

Known limitations

Official support is strongest on Apple Silicon macOS, current Windows, Linux or WSL2, and Docker; Android and Nix are best effort, while Intel macOS, PyPI installs, and Homebrew installs are unsupported.
