Not exactly. Hermes Agent is the open-source agent from Nous Research, and Hermes Desktop is its graphical app. The app uses the same agent core, config, sessions, skills and memory as the command-line version. Our catalog entry covers the desktop app.
Yes, the software is free for both. OpenClaw says there is no subscription and no hosted tier. Hermes Desktop is MIT-licensed and free to download. You may still pay a model provider, since both need model access.
OpenClaw. It bridges one gateway to Discord, iMessage, Signal, Slack, Telegram, WhatsApp and more. Hermes Desktop is a desktop window, and we found no chat-app channels in its profile.
Not for the base software in either case. Hermes Desktop needs a Nous Portal account only for cloud agents, free and discounted models and bundled tool credits. We did not confirm Nous Portal prices.
