Hermes Mobile
Native Android companion app for your Hermes AI agent.
Overview
Hermes Mobile is the native Android client for Hermes Agent. It connects to your Hermes gateway (REST API and WebSocket TUI Gateway), giving you pocket control over your AI assistant. Plain HTTP/WS connections are intended for trusted networks only; authentication does not encrypt the transport.
Support the project
If Hermes Mobile is useful to you, consider supporting its development on Ko-fi.

Features
- Real-Time Chat: Message your agent with Room-backed local database history and inline reply notifications.
- System Config: Manage active profiles, installed skills, plugins, toolsets, and LLM model/provider selections.
- Operations: Stream and filter live logs, manage cron jobs, edit environment keys, test webhooks, and monitor processes.
- Gateway Status: Monitor WebSocket connection, MCP servers, messaging channels, and OAuth providers.
- Productivity: View and manage tasks via integrated Kanban boards, track agent milestones, and browse session history.
- Analytics & Billing: Usage analytics dashboard and billing/subscription management.
- Theming: 6 built-in color presets (Default, Monochrome, Gruvbox, Catppuccin, AMOLED, Nord) plus Material You dynamic colors on supported devices.
- Modern UX: Native Material 3 design with pull-to-refresh, scroll-aware TopBar, and customizable bottom navigation.
Quick Start
- Install Hermes Mobile from F-Droid or download the APK from the latest GitHub release.
- Start your Hermes dashboard on a host reachable from your phone.
- Follow Authentication below to connect. Use a trusted network for plain HTTP/WS connections.
Build from source
Prerequisites
- JDK 21+ (required for Kotlin compilation and the Gradle toolchain)
- An Android SDK matching the compile SDK in
app/build.gradle.kts, available through Android Studio or the Nix development environment. SetANDROID_HOMEor configuresdk.dirin your locallocal.properties.
Build & Deploy
- Clone the repository:
git clone https://github.com/Hy4ri/hermes-mobile.git cd hermes-mobile - Build the debug APK:
./gradlew assembleDebug - Install on your emulator/device:
adb install app/build/outputs/apk/debug/app-debug.apk
Note: For release builds, ensure keystore environment variables (KEYSTORE_PATH, KEYSTORE_PASSWORD, KEY_ALIAS, KEY_PASSWORD) are configured, or let the GitHub Actions release workflow handle it on tag push (v*).
Nix emulator
The Nix development shell enables physical keyboard input in an existing
hermes_dev AVD configuration. It respects ANDROID_AVD_HOME and
ANDROID_USER_HOME, defaulting to ~/.android/avd.
Close any running emulator, then cold boot once to apply the setting:
nix develop --command emulator -avd hermes_dev -no-snapshot-load
Subsequent launches can omit -no-snapshot-load. Create the hermes_dev AVD
first if it does not exist; the shell does not create one.
Authentication
Once the app is installed, you need to point it at your Hermes gateway. The app auto-detects which auth mode the dashboard is using — just fill in the fields it shows.
1. Start the dashboard
On your host machine, start the dashboard:
hermes dashboard # loopback (127.0.0.1:9119) — no auth needed
hermes dashboard --host 0.0.0.0 # LAN — requires auth
For LAN access, configure credentials in ~/.hermes/config.yaml:
dashboard:
basic_auth:
username: admin # pick your own
password: hermes # pick your own
2. Connect the app
Tap Sign in on the landing screen and enter the dashboard host and port. The app probes the dashboard and reveals the fields you need:
| Auth mode | When | What you fill |
|---|---|---|
| Token only | Dashboard on same machine (loopback) | Token — grab from ~/.hermes/dashboard-token.txt or ~/.hermes/.env (HERMES_DASHBOARD_SESSION_TOKEN). The app can also auto-extract it from the dashboard page |
| Basic auth | Dashboard on LAN with password gate | Username + Password (default admin / hermes). The app logs in, gets a session cookie, and mints a WebSocket ticket automatically |
The app communicates over plain HTTP — it's designed for trusted local networks only. Do not expose your Hermes gateway to untrusted networks.
Connection profiles
Have multiple gateways? Switch between them in Settings → Connection profiles. Each profile stores its own host, port, and token — just tap to swap.
