Running Many Gateways at Once

Operate multiple profiles — each with its own bot tokens, sessions, and memory — as managed services on a single machine. This page covers the operational concerns: starting them all together, viewing logs across profiles, preventing the host from sleeping, and recovering from common launchd/systemd quirks.

If you only run one Hermes agent, you don't need this page — see Profiles for the basics.

When to use this

You want this setup when you have two or more Hermes agents that should all be online at the same time. Common reasons:

A personal assistant on one Telegram bot and a coding agent on another
One agent per family member or one per Slack workspace
Sandbox + production instances of the same configuration
A research agent + a writing agent + a cron-driven bot — each with isolated memory and skills

Every profile already gets its own per-platform LaunchAgent (ai.hermes.gateway-<name>.plist) or systemd user service (hermes-gateway-<name>.service). This guide adds the patterns for managing them collectively.

Quick start

bash

# Create profiles (once)
hermes profile create coder
hermes profile create personal-bot
hermes profile create research

# Configure each
coder setup
personal-bot setup
research setup

# Install each gateway as a managed service
coder gateway install
personal-bot gateway install
research gateway install

# Start them all
coder gateway start
personal-bot gateway start
research gateway start

That's it — three independent agents, each on its own process, restarting automatically on crash and on user login.

Start, stop, or restart all gateways at once

The CLI ships with single-profile lifecycle commands. To act across every profile, wrap them in a shell loop. Put the snippet below in ~/.local/bin/hermes-gateways and chmod +x it:

#!/bin/sh
set -eu

# Add or remove profile names here as you create / delete profiles.
profiles="default coder personal-bot research"

usage() {
  echo "Usage: hermes-gateways {start|stop|restart|status|list}"
}

run_for_profile() {
  profile="$1"
  action="$2"
  if [ "$profile" = "default" ]; then
    hermes gateway "$action"
  else
    hermes -p "$profile" gateway "$action"
  fi
}

action="${1:-}"
case "$action" in
  start|stop|restart|status)
    for profile in $profiles; do
      echo "==> $action $profile"
      run_for_profile "$profile" "$action"
    done
    ;;
  list)
    hermes gateway list
    ;;
  *)
    usage
    exit 2
    ;;
esac

Then:

bash

hermes-gateways start      # start every configured profile
hermes-gateways stop       # stop every configured profile
hermes-gateways restart    # restart all
hermes-gateways status     # status across all
hermes-gateways list       # delegates to `hermes gateway list`

:::tip The default profile is targeted with hermes gateway <action> (no -p), not hermes -p default gateway <action>. The wrapper above handles both forms. :::

Manage one profile

The shortcut commands every profile installs:

bash

coder gateway run        # foreground (Ctrl-C to stop)
coder gateway start      # start the managed service
coder gateway stop       # stop the managed service
coder gateway restart    # restart
coder gateway status     # status
coder gateway install    # create the LaunchAgent / systemd unit
coder gateway uninstall  # remove the service file

These are equivalent to hermes -p coder gateway <action> — useful if a profile alias is not on PATH or if you target profiles dynamically from a script.

Service files

Each profile installs its own service with a unique name, so installations never clash:

Platform	Path
macOS	`~/Library/LaunchAgents/ai.hermes.gateway-<profile>.plist`
Linux	`~/.config/systemd/user/hermes-gateway-<profile>.service`

The default profile keeps the historical names: ai.hermes.gateway.plist / hermes-gateway.service.

Viewing logs

Each profile writes to its own log files:

bash

# Default profile
tail -f ~/.hermes/logs/gateway.log
tail -f ~/.hermes/logs/gateway.error.log

# Named profile
tail -f ~/.hermes/profiles/<name>/logs/gateway.log
tail -f ~/.hermes/profiles/<name>/logs/gateway.error.log

Stream every profile's log simultaneously:

bash

tail -f ~/.hermes/logs/gateway.log ~/.hermes/profiles/*/logs/gateway.log

The CLI also has a structured log viewer:

bash

hermes logs -f                  # follow default profile
hermes -p coder logs -f         # follow one profile
hermes logs --help              # filters, levels, JSON output

Identify what's actually running

bash

hermes profile list             # profiles + model + gateway state
hermes-gateways status          # full status across every profile
launchctl list | grep hermes    # macOS — PIDs and labels
systemctl --user list-units 'hermes-gateway-*'   # Linux — units

Editing configuration

Every profile keeps its config inside its own directory:

~/.hermes/profiles/<name>/
├── .env              # API keys, bot tokens (chmod 600)
├── config.yaml       # model, provider, toolsets, gateway settings
└── SOUL.md           # personality / system prompt

The default profile uses ~/.hermes/ directly with the same three files.

Edit them with any editor or via the CLI:

bash

hermes config set model.model anthropic/claude-sonnet-4    # default profile
coder config set model.model openai/gpt-5                  # named profile

After editing .env or config.yaml, restart the affected gateway:

bash

coder gateway restart
# or, for everything:
hermes-gateways restart

Keeping the host awake

The gateway process can run all day, but the operating system will still try to sleep when idle. Two patterns:

macOS — `caffeinate`

caffeinate is built into macOS and prevents sleep while it runs. No install.

bash

caffeinate -dis                    # block display, idle, and system sleep
caffeinate -dis -t 28800           # same, auto-exit after 8 hours
caffeinate -i -w $(cat ~/.hermes/gateway.pid) &   # awake while default gateway runs

# Persistent: run in background and forget
nohup caffeinate -dis >/dev/null 2>&1 &
disown

# Inspect / stop
pmset -g assertions | grep -iE 'caffeinate|prevent|user is active'
pkill caffeinate

Flag	Effect
`-d`	block display sleep
`-i`	block idle system sleep (default)
`-m`	block disk sleep
`-s`	block system sleep (AC-powered Macs only)
`-u`	simulate user activity (prevents screen lock)
`-t N`	auto-exit after `N` seconds
`-w P`	exit when PID `P` exits

:::warning Lid-close still sleeps the Mac caffeinate cannot override the hardware-driven lid-close sleep on MacBooks. For lid-closed operation, change your Energy Saver / Battery preferences or use a third-party tool. :::

Linux — `systemd-inhibit` or `loginctl`

bash

# Inhibit suspend while a command runs
systemd-inhibit --what=idle:sleep --who=hermes --why="gateways running" \
  sleep infinity &

# Allow user services to keep running after logout (recommended)
sudo loginctl enable-linger "$USER"

After enabling lingering, your systemd user units (including hermes-gateway-<profile>.service) continue running across SSH disconnects and reboots.

Token-conflict safety

Each profile must use unique bot tokens for each platform. If two profiles share a Telegram, Discord, Slack, WhatsApp, or Signal token, the second gateway refuses to start with an error naming the conflicting profile.

To audit:

bash

grep -H 'TELEGRAM_BOT_TOKEN\|DISCORD_BOT_TOKEN' \
     ~/.hermes/.env ~/.hermes/profiles/*/.env

Updating the code

hermes update pulls the latest code once and syncs new bundled skills into every profile:

bash

hermes update
hermes-gateways restart

User-modified skills are never overwritten.

Troubleshooting

"Could not find service in domain for user gui: 501"

You ran hermes gateway start after a previous hermes gateway stop. The CLI's stop does a full launchctl unload, which removes the service from launchd's registry. The CLI catches this specific error on start and automatically re-loads the plist (↻ launchd job was unloaded; reloading service definition). The service starts normally. Nothing to fix.

Stale PID after a crash

If a profile's gateway shows not running but a process is still alive:

bash

ps -ef | grep "hermes_cli.*-p <profile>"
cat ~/.hermes/profiles/<profile>/gateway.pid
kill -TERM <pid>          # graceful
kill -KILL <pid>          # if that fails after a few seconds
<profile> gateway start

Forcing a hard reset of one service

bash

# macOS
launchctl unload ~/Library/LaunchAgents/ai.hermes.gateway-<profile>.plist
launchctl load   ~/Library/LaunchAgents/ai.hermes.gateway-<profile>.plist

# Linux
systemctl --user restart hermes-gateway-<profile>.service

Health check

bash

hermes doctor                  # default profile
hermes -p <profile> doctor     # one profile
