Getting Started

We offer a hosted version of Inbox Zero at https://getinboxzero.com.

Self-Hosting with Docker

The easiest way to self-host Inbox Zero is using our pre-built Docker image.

See our Self-Hosting Guide for complete instructions.

Local Development Setup

Here's a video on how to set up the project. It covers the same steps mentioned in this document. But goes into greater detail on setting up the external services.

Requirements

• Node.js >= 22.0.0
• pnpm >= 10.0.0
• Docker desktop (recommended for running Postgres and Redis)

Quick Start

1. Start PostgreSQL and Redis:

   docker compose -f docker-compose.dev.yml up -d

2. Install dependencies and set up environment:

   pnpm install
   ./docker/scripts/setup-env.sh  # Creates .env with auto-generated secrets

3. Configure OAuth and LLM:

   Edit apps/web/.env and add:

   • OAuth credentials (at least one required): Google OAuth or Microsoft OAuth
   • LLM provider: Uncomment one provider block and add your API key

4. Run database migrations:

   cd apps/web
   pnpm prisma migrate dev

5. Run the development server:

   pnpm dev

The app will be available at http://localhost:3000.

The setup script auto-generates all required secrets. The sections below cover the services you need to configure manually. For a comprehensive reference of all environment variables, see the Environment Variables Guide.

Google OAuth Setup

Go to Google Cloud Console and create a new project if necessary.

Create new credentials:

1. If the banner shows up, configure consent screen (if not, you can do this later)

   1. Click the banner, then Click Get Started.
   2. Choose a name for your app, and enter your email.
   3. In Audience, choose External
   4. Enter your contact information
   5. Agree to the User Data policy and then click Create.
   6. Return to APIs and Services using the left sidebar.

2. Create new credentials:

   1. Click the +Create Credentials button. Choose OAuth Client ID.
   2. In Application Type, Choose Web application
   3. Choose a name for your web client
   4. In Authorized JavaScript origins, add a URI and enter http://localhost:3000 (or your custom domain)
   5. In Authorized redirect URIs enter (or your custom domain):
   • http://localhost:3000/api/auth/callback/google
   • http://localhost:3000/api/google/linking/callback
   • http://localhost:3000/api/google/calendar/callback (only required for calendar integration)
   6. Click Create.
   7. A popup will show up with the new credentials, including the Client ID and secret.

3. Update .env file:

   1. Copy the Client ID to GOOGLE_CLIENT_ID
   2. Copy the Client secret to GOOGLE_CLIENT_SECRET

4. Update scopes

   1. Go to Data Access in the left sidebar (or click link above)

   3. Enter your email and press Save

6. Enable required APIs in Google Cloud Console:

   • Google People API (required)
   • Google Calendar API (only required for calendar integration)

Google PubSub Setup

PubSub enables real-time email notifications. Follow the official guide:

1. Create a topic
2. Create a subscription
3. Grant publish rights on your topic

Set GOOGLE_PUBSUB_TOPIC_NAME in your .env file.

When creating the subscription, select Push and set the URL to: https://yourdomain.com/api/google/webhook?token=TOKEN

Set GOOGLE_PUBSUB_VERIFICATION_TOKEN in your .env file to the value of TOKEN.

For local development, use ngrok to expose your local server:

ngrok http 3000

Then update the webhook endpoint in the Google PubSub subscriptions dashboard.

Email watch renewal: Gmail watch subscriptions expire periodically and must be renewed. If using Docker Compose, this is handled automatically by the cron container every 6 hours. Otherwise, set up a cron job to call /api/watch/all (see Self-Hosting Guide).

1. Navigate to Azure Active Directory
