shared-things

Sync a Things 3 project between multiple macOS users

Stop duplicating todos manually. shared-things keeps your team's Things 3 project in sync via a lightweight self-hosted server—perfect for shared shopping lists, family tasks, or team todos.

Quick Start

Client (each user)

npm install -g shared-things-daemon
shared-things init

That's it. Follow the prompts.

Features

• 🔄 Real-time sync - Changes propagate within 30 seconds
• 🏠 Self-hosted - No cloud subscription, host on your own server
• 👥 Multi-user - Each person gets their own API key
• 🤫 Background daemon - Auto-starts on login, runs silently
• 🛠️ Interactive CLI - Easy setup wizard for configuration

Prerequisites

• macOS with Things 3 installed
• Node.js >= 18
• A server running shared-things-server (see Server Setup)

Usage

Interactive Mode

shared-things init

? Server URL: https://things.yourdomain.com
? API Key: ****
? Project name in Things: Shared Project
? Things auth token: ****

Note: The Things project must be empty when you run init.

Things auth token: Required for syncing updates to existing todos. Find it in Things → Settings → General → Things URLs → Enable Things URLs.

After Setup

shared-things start     # Start daemon (auto-runs on login)
shared-things status    # Check sync status
shared-things logs -f   # Follow sync logs

stop	Stop launchd daemon
status	Show sync status & last sync time

Server Setup

One person hosts the server. Everyone else just needs an API key.

shared-things-server create-user
# → User "alice" created. API key: sk_abc123...

Production Deployment

systemd Service

sudo tee /etc/systemd/system/shared-things.service << 'EOF'
[Unit]
Description=shared-things sync server
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/shared-things-server start --port 3334
Restart=always

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl enable --now shared-things

HTTPS with Caddy

things.yourdomain.com {
    reverse_proxy localhost:3334
}

What Syncs

Synced	Not Synced
Todo title, notes, due date, tags, status	Checklist items
	Headings, Areas

Note: The project must exist in each user's Things app. Only items within that project sync.

How It Works

Things User A ←→ Daemon A ←→ Server ←→ Daemon B ←→ Things User B

Each daemon polls Things every 30 seconds via AppleScript, pushes changes to the server, and pulls updates to apply via Things URL Scheme. Server is the single source of truth (last write wins).

Development
