    Target audience
    Developers and power users who want a self-hostable, model-agnostic agent with persistent memory and messaging integrations. Not ideal for: non-technical users who only want a managed chat UI with no setup, or teams that need closed enterprise SaaS with SSO out of the box.

    Pricing notes
    Verified August 2026 at https://portal.nousresearch.com/ and https://hermes-agent.nousresearch.com/. Hermes Agent software is free under MIT; you pay for model tokens and hosting. Optional Nous Portal: Free ($0, free models only); Plus ($20/mo); Super ($100/mo); Ultra ($200/mo) with monthly credits and Tool Gateway access. Hermes Cloud hosting bills from the same credit balance. You can also self-host with your own API keys (OpenRouter, OpenAI, Anthropic, Ollama, etc.).

    Pros

    • Truly free to install and fork (MIT)

    Cons

    • Real cost is opaque until you pick models, tools, and hosting
    • Self-host setup is heavier than consumer chat apps
    • Portal Tool Gateway and paid models sit behind subscription credits
    • Enterprise SSO and admin polish lag managed SaaS agents

    Review notes

    Context from the listing review and editorial research.

    NEW tool. Distinct from Nous's Hermes LLM model family name: this entry is the agent at hermes-agent.nousresearch.com and github.com/NousResearch/hermes-agent. Strong open-source fit for the directory. Compared often with Grok Bot and OpenClaw-class stacks.
