Claude Duet vs Hermes Agent

Duet is a hosted preview for eligible Claude users. Hermes is a configurable agent system you operate. Choose according to supported apps and operating effort, not an assumed equivalence between two personal agents.

How to choose between these options

Duet provides a product experience around Claude context, briefs and background assignments, with a defined set of preview limits. Hermes allows more decisions about the model, execution backend, integrations and memory arrangement. That is useful when those choices are requirements, but it is additional engineering work rather than a ready-made substitute for every Duet feature.

Test a small scheduled summary and inspect both the result and what happens when work pauses. A self-managed backend needs to be running; Duet's periodic checks use shared Claude allowances. For confidential material, review the entire data path and retention behavior rather than inferring privacy from where the client is installed.

Documented comparison: Claude Duet vs Hermes Agent
Decision	Claude Duet	Hermes Agent
What it is	A cloud agent for briefs, connected business apps and assignments that continue while you are away.	Agent software you operate, with configurable models, execution backends, persistent memory and reusable skills.
Can I use it? · documented	Research preview for US Pro/Max users invited from a waitlist. Not available to Team or Enterprise yet. Announced 21 October, with a safety update on 23 October.	Open-source software with desktop and CLI options. Supported platforms and execution backends vary; this is an operated deployment, not a hosted-plan entitlement.
Where work runs · documented	Own cloud computer and browser; tasks continue after the app closes. The current preview cannot access files on your local computer.	Local machine, containers, SSH or supported cloud backends. Jobs need the configured backend and gateway running; a sleeping local host is not always-on hosting.
How usage is paid for · documented	Included in Pro/Max during preview, sharing Claude's session and weekly limits. Background account checks consume that allowance.	MIT software is free. Budget for model/API subscriptions, tool services, hosting or hardware/electricity and maintenance. Optional Nous Portal bundles models and tools; some infrastructure costs remain separate.
What keeps running · documented	Morning briefs, account checks every few hours and longer tasks while you are away. It is not an immediate-response monitoring service.	Scheduled jobs, subagents and persistent Bot routines, with the appropriate running backend and gateway configuration.
Browser and computer tools · documented	Connected apps/plugins and a cloud browser for other sites. You cannot watch or take over that browser yet; there is no model picker.	Configurable browser automation, terminal/files, plugins and MCP. Backend and model endpoint choices determine where execution and data processing happen.
What it remembers · documented	Claude memory, skills, connections and eligible past chats. Disconnecting an app does not erase what it learned; memory can be reset.	Local memory/profile files, session search and reusable skills; optional external memory providers. Check that requested memory writes occurred. Learning here is persisted context, not model-weight training.
Approvals and data boundaries · documented	Vendor describes consequential-action approvals, separate intent/privacy checks and isolated credential handling. Some actions remain prohibited despite approval; these controls are not a performance guarantee.	Command approvals, allowlists and isolation options depend on operator configuration. Command matching is not an OS sandbox. Cloud model, tool and memory services have separate data policies.
Decision-changing limits · documented	No Microsoft 365 yet, limited Slack functionality, no local files or browser takeover, and no outbound calls or SMS to others. Personal errands are less developed than work tasks.	Deployment, upgrades, secrets and uptime are your responsibility. A small local model is not equivalent to a frontier hosted one; evaluate the exact stack rather than the agent name alone.

A fair comparison starts with the same job. Models, agent products, automation platforms and inference engines are not interchangeable. The second selector narrows to compatible entries. Even then, use the same task, configuration and hardware for an actual test.

A few useful starting points.
