Hermes Desktop by Nous Research

Hermes Desktop is the official native desktop application for Hermes Agent, the open-source autonomous AI agent from Nous Research. Released in public preview in June 2026 for macOS, Windows, and Linux, it wraps a polished graphical interface around the same agent that previously ran only through the command line and messaging gateways. Per Nous Research's documentation, it is not a separate product or a lightweight clone. It shares the same agent core, configuration, API keys, sessions, skills, and memory as every other Hermes surface.

What It Is

Hermes Desktop is a chat-first native window that drives Hermes Agent through a purpose-built UI instead of a terminal. The core agent, which is a self-improving, model-agnostic system that lives on a server and grows more capable over time, is documented on the main Hermes Agent listing; the desktop app is one of several front ends over that single agent, alongside the CLI, the terminal UI, and the browser-based web dashboard. The docs state that anything you set up in the terminal is already present in the app, and anything you do in the app shows up in the terminal, because both installs use the same on-disk layout and are interchangeable.

One Agent, Every Surface

• Shared state — Sessions started in the desktop app resume in the CLI, TUI, or web dashboard and vice versa, since all surfaces talk to one agent core with one set of config, keys, skills, and memory.
• Interchangeable front ends — Nous Research frames the desktop app, terminal interfaces, and web dashboard as entry points you switch between freely rather than competing products.
• Local or remote — By default the app manages its own local backend, but it can attach to a Hermes instance running elsewhere so the heavy lifting happens off your laptop.

Inside the Desktop App

• Streaming chat — Live tool activity and structured tool-call summaries appear as the agent works.
• Side-by-side preview rail — Render web pages, files, and tool outputs next to the conversation without leaving the chat.
• File browser — Explore and preview the working directory as the agent reads, writes, and edits files.
• Voice mode — Talk to Hermes and hear its replies, the same voice mode available on other surfaces.
• Settings and onboarding UI — Manage providers, models, tools, MCP servers, and credentials from a real interface instead of editing YAML, with first-run onboarding to your first message.
• Management panes — Dedicated views for skills, scheduled cron jobs, profiles, messaging channels, and multi-agent orchestration.

Installing on macOS, Windows, and Linux

Nous Research describes three install paths. On macOS and Windows, a downloadable installer is the recommended route. On any platform, adding an include-desktop flag to the standard CLI install script bundles the app, and anyone with an existing Hermes install can open the GUI with a single command. According to the docs, the packaged app ships only the Electron shell and installs the Hermes Agent runtime on first launch into the same home directory a CLI install uses, then checks for updates in the background and offers one-click updates when they are ready.

Connecting to a Remote Backend

A defining desktop feature is pointing the app at a Hermes backend running on another machine — a VPS, a home server, or a Mac Mini behind Tailscale — instead of the bundled local backend. The docs describe configuring this under Settings, then Gateway, then Remote gateway, using a remote URL and a session token, so a long-running agent can stay on a server while you chat from a lightweight native window. Nous Research warns that the remote port should be kept behind a VPN rather than exposed to the open internet.

Update: Hermes Desktop Public Preview

The desktop app launched in public preview in early June 2026 on top of Hermes Agent v0.15.2 (build 2026.5.29.2), the release published May 29, 2026. Coverage from The Decoder and MarkTechPost describes it as a native cross-platform front end that reuses the existing agent core, adding streaming tool output, the preview pane, file browser, voice I/O, and a settings UI to what had been a terminal-and-messaging-only experience.
