Installation

Install the HAPI CLI and set up the hub.

Prerequisites

Claude Code, OpenAI Codex CLI, Google Gemini CLI, or OpenCode CLI installed

Verify your CLI is installed:

bash

# For Claude Code
claude --version

# For OpenAI Codex CLI
codex --version

# For Google Gemini CLI
gemini --version

# For OpenCode CLI
opencode --version

Architecture

HAPI has three components:

Component	Role	Required
CLI	Wraps AI agents (Claude/Codex/Gemini/OpenCode), runs sessions	Yes
Hub	Central coordinator: persistence, real-time sync, remote access	Yes
Runner	Background service for remote session spawning	Optional

CLI: Start a session with hapi. The CLI wraps your AI agent and syncs with the hub.
Hub: Run hapi hub. Stores sessions, handles permissions, enables remote access.
Runner: Run hapi runner start. Lets you spawn sessions from phone/web without keeping a terminal open.

Typical workflows

Local only: hapi hub → hapi → work in terminal

Remote access: hapi hub --relay → hapi runner start → control from phone/web

Install the CLI

bash

npm install -g @twsxtd/hapi

Or with Homebrew:

bash

brew install tiann/tap/hapi

Other install options

npx (no install)

bash

npx @twsxtd/hapi

Prebuilt binary

Download the latest release from GitHub Releases.

bash

xattr -d com.apple.quarantine ./hapi
chmod +x ./hapi
sudo mv ./hapi /usr/local/bin/

Build from source

bash

git clone https://github.com/tiann/hapi.git
cd hapi
bun install
bun build:single-exe

./cli/dist/hapi

Hub setup

The hub can be deployed on:

Local desktop (default) - Run on your development machine
Remote host - Deploy the hub on a VPS, cloud host, or any machine with network access

Default: Public Relay (recommended)

bash

hapi hub --relay

The terminal displays a URL and QR code. Scan to access from anywhere.

hapi server remains supported as an alias.

End-to-end encrypted with WireGuard + TLS
No configuration needed
Works behind NAT, firewalls, and any network

Local Only

bash

hapi hub
# or
hapi hub --no-relay

The hub listens on http://localhost:3006 by default.

On first run, HAPI:

Creates ~/.hapi/
Generates a secure access token
Prints the token and saves it to ~/.hapi/settings.json

Config files

~/.hapi/
├── settings.json      # Main configuration
├── hapi.db           # SQLite database (hub)
├── runner.state.json  # Runner process state
└── logs/             # Log files

Environment variables

Variable	Default	Description
`CLI_API_TOKEN`	Auto-generated	Shared secret for authentication
`HAPI_API_URL`	`http://localhost:3006`	Hub URL for CLI
`HAPI_LISTEN_HOST`	`127.0.0.1`	HTTP service bind address
`HAPI_LISTEN_PORT`	`3006`	HTTP service port
`HAPI_PUBLIC_URL`	-	Public URL for external access
`HAPI_HOME`	`~/.hapi`	Config directory path
`DB_PATH`	`~/.hapi/hapi.db`	Database file path
`CORS_ORIGINS`	-	Allowed CORS origins
`ELEVENLABS_API_KEY`	-	ElevenLabs API key for voice
`ELEVENLABS_AGENT_ID`	Auto-created	Custom ElevenLabs agent ID

CLI setup

If the hub is not on localhost, set these before running hapi:

bash

export HAPI_API_URL="http://your-hub:3006"
export CLI_API_TOKEN="your-token-here"

Or use interactive login:

bash

hapi auth login

Authentication commands:

bash

hapi auth status
hapi auth login
hapi auth logout

Each machine gets a unique ID stored in ~/.hapi/settings.json. This allows:

Multiple machines to connect to one hub
Remote session spawning on specific machines
Machine health monitoring

Operations

Self-hosted tunnels

If you prefer not to use the public relay (e.g., for lower latency or self-managed infrastructure), you can use these alternatives:

Cloudflare Tunnel

https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/

Quick tunnel (temporary URL, changes on restart):

bash

# Install cloudflared: https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/
cloudflared tunnel --protocol http2 --url http://localhost:3006

Copy the generated URL and set it:

bash

export HAPI_PUBLIC_URL="https://your-tunnel.trycloudflare.com"
hapi hub

Named tunnel (persistent URL):

bash

# Create and configure a named tunnel
cloudflared tunnel create hapi
cloudflared tunnel route dns hapi hapi.yourdomain.com

# Run the tunnel
cloudflared tunnel --protocol http2 run hapi

Note: Use --protocol http2 instead of QUIC (the default) to avoid potential timeout issues with long-lived connections.

Tailscale

https://tailscale.com/download

bash

sudo tailscale up
hapi hub

Access via your Tailscale IP:

http://100.x.x.x:3006

Public IP / Reverse Proxy

If the hub has a public IP, access directly via http://your-hub-ip:3006.

Use HTTPS (via Nginx, Caddy, etc.) for production.

Telegram setup

Enable Telegram notifications and Mini App access:

Message @BotFather and create a bot
Set the bot token and public URL
Start the hub and bind your account

bash

export TELEGRAM_BOT_TOKEN="your-bot-token"
export HAPI_PUBLIC_URL="https://your-public-url"

hapi hub

Then message your bot with /start, open the app, and enter your CLI_API_TOKEN.

Troubleshooting:

If binding fails, verify HAPI_PUBLIC_URL is accessible from the internet
Telegram Mini App requires HTTPS (not HTTP)

Runner setup

Run a background service for remote session spawning:

bash

hapi runner start
hapi runner status
hapi runner logs
hapi runner stop

With the runner running:

Your machine appears in the "Machines" list
You can spawn sessions remotely from the web app
Sessions persist even when the terminal is closed

Alternative: pm2

If you prefer pm2 for process management:

bash

pm2 start "hapi runner start --foreground" --name hapi-runner
pm2 save

Background service deployment

Keep HAPI running persistently so it survives terminal closes, system restarts, and continues running in the background.

Quick: nohup

Simple one-liner for quick background runs:

bash

# Hub
nohup hapi hub --relay > ~/.hapi/logs/hub.log 2>&1 &

# Runner
nohup hapi runner start --foreground > ~/.hapi/logs/runner.log 2>&1 &

View logs:

bash

tail -f ~/.hapi/logs/hub.log
tail -f ~/.hapi/logs/runner.log

Stop processes:

bash

pkill -f "hapi hub"
pkill -f "hapi runner"

pm2 (recommended for Node.js users)

pm2 provides process management with auto-restart on crashes and system reboot.

bash

# Install pm2
npm install -g pm2

# Start hub and runner
pm2 start "hapi hub --relay" --name hapi-hub
pm2 start "hapi runner start --foreground" --name hapi-runner

# View status and logs
pm2 status
pm2 logs hapi-hub
pm2 logs hapi-runner

# Auto-restart on system reboot
pm2 startup    # Follow the printed instructions
pm2 save       # Save current process list

macOS: launchd

Create plist files for automatic startup on macOS.

Hub (~/Library/LaunchAgents/com.hapi.hub.plist):

xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Load/unload services:

bash

# Load (start)
launchctl load ~/Library/LaunchAgents/com.hapi.hub.plist
launchctl load ~/Library/LaunchAgents/com.hapi.runner.plist

# Unload (stop)
launchctl unload ~/Library/LaunchAgents/com.hapi.hub.plist
launchctl unload ~/Library/LaunchAgents/com.hapi.runner.plist

macOS sleep note: macOS may suspend background processes when the display sleeps. Use caffeinate to prevent this:
bash
caffeinate -dimsu hapi hub --relay
Or run caffeinate -dimsu in a separate terminal while HAPI is running.

Linux: systemd

Create user-level systemd services for automatic startup.

Hub (~/.config/systemd/user/hapi-hub.service):

ini

[Unit]
Description=HAPI Hub
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/bin/hapi hub --relay
Restart=always
RestartSec=5

[Install]
WantedBy=default.target

Runner (~/.config/systemd/user/hapi-runner.service):

ini

[Unit]
Description=HAPI Runner
After=network.target hapi-hub.service

[Service]
Type=simple
ExecStart=/usr/local/bin/hapi runner start --foreground
Restart=always
RestartSec=5

[Install]
WantedBy=default.target

Enable and start:

bash

# Reload systemd
systemctl --user daemon-reload

# Enable (auto-start on login)
systemctl --user enable hapi-hub
systemctl --user enable hapi-runner

# Start now
systemctl --user start hapi-hub
systemctl --user start hapi-runner

# View status/logs
systemctl --user status hapi-hub
journalctl --user -u hapi-hub -f

Persist after logout: To keep services running even when not logged in:
bash
loginctl enable-linger $USER

Voice assistant setup

Enable voice control:

Get an API key from elevenlabs.io
Set the environment variable:

bash

export ELEVENLABS_API_KEY="your-api-key"
hapi hub --relay

See Voice Assistant for usage details.

Security notes

Keep tokens secret and rotate if needed
Use HTTPS for public access
Restrict CORS origins in production

Firewall example (ufw)

bash

ufw allow from 192.168.1.0/24 to any port 3006
