We file it under AI agent builders, the category of tools to build your own AI agents, and it also overlaps with workflow automation and aI coding assistants. The category lists 20 verified tools on this site.
The publisher is Nous Research, Inc., based in United States. The service launched in 2026: it is still very new.
Who is it for?
It is mostly useful to these profiles: developers, researchers, and freelancers. The need it covers is simple to state: build your own AI agents.
Hermes Agent is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you also work from your phone
- you want to read the code or host it yourself
The best test is a concrete case from your daily work: if the tool does not beat your current method within a week, move on to an alternative.
How much does Hermes Agent cost?
Pricing model: open source (public code). A free plan is offered, usually limited in volume or features.
The first paid plan costs $20 per month (Nous Portal Plus, optional; free agent and external models billed separately), according to the pricing page, checked on October 24, 2026.
Per month, that is close to the category median ($20 per month, based on tools with a published price).
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
The publisher does not clearly state where data is hosted. Assume your content may leave your region.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
Exporting your content: yes (details on the official site). Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
Hermes Agent runs on: Windows, macOS, Linux, Android, API, Slack, and Microsoft Teams.
The interface is available in 17 languages.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
The source code is public: NousResearchNousResearch/hermes-agent.
How we scored it
