The biggest difference between Hermes Agent and Claude Code, Cursor, and Codex is the running form. Claude Code is more of a terminal coding assistant, Cursor is more of an IDE experience, and Codex is more of an OpenAI programming workflow. Hermes Agent is more like a general-purpose agent that can be deployed behind a CLI, VPS, chat platform, or API server for a long time.
How to choose
Write code only in the IDE: Cursor is more convenient.
Major terminal code change: Claude Code or Codex experience is more direct.
If you want to connect with Telegram, Discord, cron, MCP, skills, memory and server automation: Hermes Agent is for you.
The cost of Hermes Agent
It's more flexible, but also more configurable. You need to understand concepts such as provider, tools, gateway, memory, skills, MCP, etc. For beginners, run the CLI and a model first, don't start all the way out.
In a word: Hermes Agent is not a single IDE plugin, but an autonomous agent that can be deployed to multiple scenarios.
