Brooklyn Nicholson a1cda2410b fix(desktop): self-update rebuilds and relaunches cleanly on macOS
The macOS DMG / in-app update could leave Hermes unable to relaunch: the
staged updater rebuilt the desktop without managed Node on PATH ("npm not
found"), never installed the rebuilt bundle over the running app, and could
race itself on `git stash`. Child install scripts also inherited a deleted
cwd from the .app bundle replaced during self-update.

- update.rs: prepend $HERMES_HOME/node/bin + venv bin to the rebuild PATH;
  read --branch / --target-app from args; add a macOS "install" stage that
  dittos the rebuilt bundle over the target app, clears quarantine, and
  relaunches via `open` (rolling back on a failed swap); guard start_update
  with an AtomicBool so concurrent startUpdate() calls can't race git stash.
- main.cjs: pass --branch <configured> and --target-app <running bundle> to
  the staged updater, and spawn it with HERMES_HOME + managed Node/venv on
  PATH and cwd=HERMES_HOME.
- bootstrap.rs: launch the desktop via `open <App>.app` on macOS instead of
  exec'ing Contents/MacOS/Hermes, avoiding cwd/quarantine issues post-rebuild.
- powershell.rs: pin child install scripts to a stable cwd so they don't emit
  getcwd errors when the launching .app is replaced mid-install.
- failure.tsx: in update mode show "Update didn't finish" / "Retry update"
  and retry via startUpdate() instead of re-running the installer bootstrap.

Hermes Desktop ☤

Download Documentation Discord License: MIT

The native desktop app for Hermes Agent — the self-improving AI agent from Nous Research. Same agent, same skills, same memory as the CLI and gateway, in a polished native window — chat with streaming tool output, side-by-side previews, a file browser, voice, and settings, no terminal required. Available for macOS, Windows, and Linux.

Chat with the full agentStreaming responses, live tool activity, structured tool summaries, and the same conversation history as every other Hermes surface.
Side-by-side previewsRender web pages, files, and tool outputs in a right-hand pane while you keep chatting.
File browserExplore and preview the working directory without leaving the app.
VoiceTalk to Hermes and hear it back.
Settings & onboardingManage providers, models, tools, and credentials from a real UI. First-run setup gets you to your first message in seconds.
Stays currentBuilt-in updates pull the latest agent and rebuild the app in place.

Install

Add --include-desktop to the one-line installer and it sets up the agent and builds the desktop app in one go:

curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash -s -- --include-desktop

Already have the Hermes CLI? Just run:

hermes desktop

It builds and launches the GUI against your existing install — same config, keys, sessions, and skills. On first launch Hermes walks you through picking a provider and model; nothing else to configure.

Prebuilt installers

When a release ships desktop installers they're attached to its releases page.dmg (macOS), .exe / .msi (Windows), .AppImage / .deb / .rpm (Linux). These are published manually, so the install-with-Hermes path above is the most reliable way to get the latest.


Updating

The app checks for updates in the background and offers a one-click update when one is ready. You can also update any time from the CLI:

hermes update

Requirements

The installer handles everything for you (Python 3.11+, a portable Git, ripgrep). The only thing worth knowing:

  • Windows — the installer bundles its own Git and Python; no admin rights or system changes required.
  • macOS / Linux — uses your system Python 3.11+ (installed automatically if missing).

Development

Want to hack on the app itself? Install workspace deps from the repo root once, then run the dev server from this directory:

npm install          # from repo root — links apps/desktop, web, apps/shared
cd apps/desktop
npm run dev          # Vite renderer + Electron, which boots the Python backend

Point the app at a specific source checkout, or sandbox it away from your real config:

HERMES_DESKTOP_HERMES_ROOT=/path/to/clone npm run dev
HERMES_HOME=/tmp/throwaway npm run dev
npm run dev:fake-boot   # exercise the startup overlay with deterministic delays

Building installers

npm run dist:mac     # DMG + zip
npm run dist:win     # NSIS + MSI
npm run dist:linux   # AppImage + deb + rpm
npm run pack         # unpacked app under release/ (no installer)

Installers are built and uploaded to GitHub Releases manually. macOS/Windows signing & notarization happen automatically when the relevant credentials are present in the environment (CSC_LINK / CSC_KEY_PASSWORD / APPLE_* for macOS, WIN_CSC_* for Windows).

How it works

The packaged app ships only the Electron shell. On first launch it installs the Hermes Agent runtime into HERMES_HOME (~/.hermes, or %LOCALAPPDATA%\hermes on Windows) — the same layout a CLI install uses, so the two are interchangeable. The renderer (React, in src/) talks to a hermes dashboard --tui backend over the standard gateway APIs and reuses the embedded TUI rather than reimplementing chat. The install, backend-resolution, and self-update logic all live in electron/main.cjs.

Verification

Run before opening a PR (lint may surface pre-existing warnings but must exit cleanly):

npm run fix
npm run type-check
npm run lint
npm run test:desktop:all

Troubleshooting

Boot logs land in HERMES_HOME/logs/desktop.log (includes backend output and recent Python tracebacks) — check it first if the app reports a boot failure.

macOS / Linux:

# Force a clean first-launch setup
rm "$HOME/.hermes/hermes-agent/.hermes-bootstrap-complete"
# Rebuild a broken Python venv
rm -rf "$HOME/.hermes/hermes-agent/venv"
# Reset a stuck macOS microphone prompt (macOS only)
tccutil reset Microphone com.nousresearch.hermes

Windows (PowerShell):

# Force a clean first-launch setup
Remove-Item "$env:LOCALAPPDATA\hermes\hermes-agent\.hermes-bootstrap-complete"
# Rebuild a broken Python venv
Remove-Item -Recurse -Force "$env:LOCALAPPDATA\hermes\hermes-agent\venv"

The default Hermes home on Windows is %LOCALAPPDATA%\hermes. Set the HERMES_HOME env var if you've relocated it.
