Fixes #54527 — a message typed into one TUI session could be silently misrouted into (or overwritten by) another concurrently-open session. Root cause: activeQueueSessionKeyRef is written on every render, but the debounced draft-persist timer, the pagehide flush, and dispatchSubmit's reject-restore path all read it lazily at async-resolve time instead of capturing the scope that was active when the operation started. A session switch landing between capture and resolve relabels one session's text under the other session's key. A large paste widens the window (slower synchronous render), which matches the original report. Fix: introduce draftScopeRef, written only by the draft-swap effect (so it always reflects the session whose text is actually loaded in the editor) and read it instead of the render-time ref at both async write sites. dispatchSubmit's restore() now uses the submittedScope already captured at dispatch instead of re-reading the live ref. Also adds isPendingDraftPersistCurrent as defense-in-depth: before the debounce timer commits a write, it verifies its captured {scope, text} pair is still the one on file. This is a no-op under the fix above (a session swap or a newer keystroke already clears/replaces the pending entry via clearTimeout), but turns any future regression that reintroduces a stale/live-ref read at this call site into a dropped write instead of a silent cross-session misroute.

Hermes Desktop ☤
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 agent | Streaming responses, live tool activity, structured tool summaries, and the same conversation history as every other Hermes surface. |
| Side-by-side previews | Render web pages, files, and tool outputs in a right-hand pane while you keep chatting. |
| File browser | Explore and preview the working directory without leaving the app. |
| Voice | Talk to Hermes and hear it back. |
| Settings & onboarding | Manage providers, models, tools, and credentials from a real UI. First-run setup gets you to your first message in seconds. |
| Stays current | Built-in updates pull the latest agent and rebuild the app in place. |
Install
Install with Hermes (recommended)
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
Prebuilt installers are built and distributed via the Hermes Desktop website..
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).
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:
# throwaway HERMES_HOME, separate Electron userData, distinct app name to avoid the single-instance lock
../scripts/dev-sandbox.sh npm run dev
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 the Electron shell and a native React chat surface. On first launch it can install 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. Backend resolution first honours HERMES_DESKTOP_HERMES_ROOT, then a completed managed install, then a probed hermes on PATH (unless HERMES_DESKTOP_IGNORE_EXISTING=1 is set), and finally an explicit HERMES_DESKTOP_HERMES command override for packagers/troubleshooting. The renderer (React, in src/) talks to a headless backend the app launches for you — a hermes serve process that serves the tui_gateway JSON-RPC/WebSocket API — through the framework-agnostic client in apps/shared (the same client the web dashboard consumes), and reuses the agent runtime rather than embedding hermes --tui. The app is self-contained: it runs its own hermes serve backend and never opens or requires the web dashboard UI. (For backward compatibility, a runtime that predates the serve command automatically falls back to a headless dashboard --no-open — see electron/backend-command.ts — so mid-upgrade installs never break.) The install, backend-resolution, and self-update logic all live in electron/main.ts.
Verification
Run before opening a PR (lint may surface pre-existing warnings but must exit cleanly):
npm run fix
npm run typecheck
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 theHERMES_HOMEenv var if you've relocated it.
