Hermes Agent is an open-source agent from Nous Research that you host yourself and talk to from the terminal or chat apps like Telegram and Slack. Claude Code is Anthropic's coding agent for the terminal, editors, a desktop app and the browser, and it comes with a paid Claude plan from $20 a month (as of November 2026). Hermes is MIT-licensed and works with many model providers, Anthropic's Claude among them. Claude Code is not open source and runs Claude models, with Opus 5.5 as the default on paid plans.
Good for
- Developers who want an agent they host and own
- Claude Code users curious about open-source agents
- People who want to message an agent from Telegram, Slack or Discord
- Teams choosing between one model vendor and many
Side by side
Our advice: pick Claude Code for a supported coding agent tied to Claude models and a Claude plan. Pick Hermes Agent if you want to host the agent yourself, choose your own model provider and reach it from chat apps.

Which to pick
Our advice: pick Claude Code if you want a supported coding agent on a Claude plan with the least setup. Pick Hermes Agent if you want to host the agent, choose the model, and message it from chat apps. You can run Claude models in either.
The main limit on each side: Claude Code needs a paid Claude plan, and Hermes needs you to set up a model provider and host it.
Best for
- Claude Code: people who want Claude models in the terminal, an editor or the browser with one sign-in
- Claude Code: teams already on a Claude Team or Enterprise plan
- Hermes Agent: people who want an open-source agent they can inspect and host
- Hermes Agent: anyone who wants to switch between model providers
- Hermes Agent: people who want an agent reachable from Telegram, Slack or Discord
Skip it if
- Claude Code: you want to read or change the agent's source, since it is not open source
- Hermes Agent: you want a single sign-in with no provider setup
Questions
What is Hermes Agent?
Hermes Agent is an open-source AI agent from Nous Research. It remembers what it learns across sessions, builds reusable skills, and runs on your own machine or a server. This page compares that software with Claude Code.
Is Hermes Agent a Claude Code alternative?
Partly. Both run tools and commands for you and both support MCP servers and skills. Hermes describes itself as an autonomous agent rather than a coding copilot tied to an editor, so it covers more than coding.
Is Hermes Agent free?
The software is free and MIT-licensed. You still connect a model provider, such as Nous Portal, OpenRouter, Anthropic or OpenAI, and that provider sets the price.
Can Hermes use Claude models?
Yes, in two ways. An Anthropic API key works and is billed per token. Signing in with a Claude account works only on a Claude Max plan with purchased extra usage credits, and Claude Pro cannot use the sign-in path (per the Hermes providers page, as of November 2026).
Is Hermes better than Claude Code?
Neither vendor publishes a head-to-head test, so no one can say for certain. They suit different setups: Claude Code is a product from the model maker, and Hermes is an open agent you host and point at the model you choose.
Does Hermes Agent support MCP?
Yes. Hermes connects to MCP servers and can filter which of their tools it uses. Claude Code supports MCP too, so many of the same servers work in both.
Can I run Hermes on a server and message it from my phone?
Yes. Hermes can run on a VPS, in Docker or on cloud sandboxes, and one gateway connects it to more than 20 chat apps including Telegram, Discord, Slack and WhatsApp.
Does Hermes work inside code editors?
Yes. The Agent Client Protocol site lists Hermes Agent as an agent that editors with ACP support can run.
Can Hermes delete files or run risky commands?
It can run commands, so it asks you first. Hermes checks each command against a list of dangerous patterns and needs your approval when one matches. Claude Code also asks before it changes things in its default mode.
