About

There are two parts to Inbox Zero:

1. An AI email assistant that helps you spend less time on email.
2. Open source AI email client.

If you're looking to contribute to the project, the email client is the best place to do this.

Thanks to Vercel for sponsoring Inbox Zero in support of open-source software.

Getting Started for Developers

We offer a hosted version of Inbox Zero at https://getinboxzero.com. To self-host follow the steps below.

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 >= 18.0.0
• pnpm >= 8.6.12
• Docker desktop (recommended but optional)

Make sure you have the above installed before starting.

The external services that are required are (detailed setup instructions below):

• Google OAuth
• Google PubSub

Updating .env file: secrets

Create your own .env file from the example supplied:

cp apps/web/.env.example apps/web/.env
cd apps/web
pnpm install

Set the environment variables in the newly created .env. You can see a list of required variables in: apps/web/env.ts.

The required environment variables:

Secrets:

• NEXTAUTH_SECRET -- can be any random string (try using openssl rand -hex 32 for a quick secure random string)
• GOOGLE_ENCRYPT_SECRET -- Secret key for encrypting OAuth tokens (try using openssl rand -hex 32 for a secure key)
• GOOGLE_ENCRYPT_SALT -- Salt for encrypting OAuth tokens (try using openssl rand -hex 16 for a secure salt)

Redis:

• UPSTASH_REDIS_URL -- Redis URL from Upstash. (can be empty if you are using Docker Compose)
• UPSTASH_REDIS_TOKEN -- Redis token from Upstash. (or specify your own random string if you are using Docker Compose)

When using Vercel with Fluid Compute turned off, you should set MAX_DURATION=300 or lower. See Vercel limits for different plans here.

Updating .env file with Google OAuth credentials:

• GOOGLE_CLIENT_ID -- Google OAuth client ID. More info here
• GOOGLE_CLIENT_SECRET -- Google OAuth client secret. More info here

Go to Google Cloud. 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
   5. In Authorized redirect URIs enter http://localhost:3000/api/auth/callback/google
   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)
   2. Click Add or remove scopes
   3. Copy paste the below into the Manually add scopes box:

   https://www.googleapis.com/auth/userinfo.profile
   https://www.googleapis.com/auth/userinfo.email
   https://www.googleapis.com/auth/gmail.modify
   https://www.googleapis.com/auth/gmail.settings.basic
   https://www.googleapis.com/auth/contacts
   

   4. Click Update
   5. Click Save in the Data Access page.

5. Add yourself as a test user

   1. Go to Audience
   2. In the Test users section, click +Add users
   3. Enter your email and press Save

Updating .env file with LLM parameters

You need to set an LLM, but you can use a local one too:

• Anthropic
• OpenAI
• AWS Bedrock Anthropic
• Google Gemini
• Groq Llama 3.3 70B
• Ollama (local)

For the LLM, you can use Anthropic, OpenAI, or Anthropic on AWS Bedrock. You can also use Ollama by setting the following enviroment variables:

OLLAMA_BASE_URL=http://localhost:11434/api
NEXT_PUBLIC_OLLAMA_MODEL=phi3

Note: If you need to access Ollama hosted locally and the application is running on Docker setup, you can use http://host.docker.internal:11434/api as the base URL. You might also need to set OLLAMA_HOST to 0.0.0.0 in the Ollama configuration file.

You can select the model you wish to use in the app on the /settings page of the app.

If you are using local ollama, you can set it to be default:

DEFAULT_LLM_PROVIDER=ollama

Redis and Postgres

We use Postgres for the database. For Redis, you can use Upstash Redis or set up your own Redis instance.

You can run Postgres & Redis locally using docker-compose

docker-compose up -d # -d will run the services in the background

Running the app

To run the migrations:

pnpm prisma migrate dev

To run the app locally for development (slower):

pnpm run dev

Or from the project root:

turbo dev

To build and run the app locally in production mode (faster):

pnpm run build
pnpm start

Open http://localhost:3000 to view the app in your browser.

Premium

Many features are available only to premium users. To upgrade yourself, make yourself an admin in the .env: [email protected] Then upgrade yourself at: http://localhost:3000/admin.

Set up push notifications via Google PubSub to handle emails in real time

Follow instructions here.

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

Set env var GOOGLE_PUBSUB_TOPIC_NAME. When creating the subscription select Push and the url should look something like: https://www.getinboxzero.com/api/google/webhook?token=TOKEN or https://abc.ngrok-free.app/api/google/webhook?token=TOKEN where the domain is your domain. Set GOOGLE_PUBSUB_VERIFICATION_TOKEN in your .env file to be the value of TOKEN.

To run in development ngrok can be helpful:

ngrok http 3000
# or with an ngrok domain to keep your endpoint stable (set `XYZ`):
ngrok http --domain=XYZ.ngrok-free.app 3000

And then update the webhook endpoint in the Google PubSub subscriptions dashboard.

To start watching emails visit: /api/google/watch/all

Watching for email updates

Set a cron job to run these: The Google watch is necessary. Others are optional.

  "crons": [
    {
      "path": "/api/google/watch/all",
      "schedule": "0 1 * * *"
    },
    {
      "path": "/api/resend/summary/all",
      "schedule": "0 16 * * 1"
    },
    {
      "path": "/api/reply-tracker/disable-unused-auto-draft",
      "schedule": "0 3 * * *"
    }
  ]

Here are some easy ways to run cron jobs. Upstash is a free, easy option. I could never get the Vercel vercel.json. Open to PRs if you find a fix for that.
