Getting Started for Developers

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

Self-Hosting with Docker on VPS

For a complete guide on deploying Inbox Zero to a VPS using Docker, see our Docker Self-Hosting Guide.

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):

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:

AUTH_SECRET -- can be any random string (try using openssl rand -hex 32 for a quick secure random string)
EMAIL_ENCRYPT_SECRET -- Secret key for encrypting OAuth tokens (try using openssl rand -hex 32 for a secure key)
EMAIL_ENCRYPT_SALT -- Salt for encrypting OAuth tokens (try using openssl rand -hex 16 for a secure salt)
NEXT_PUBLIC_BASE_URL -- The URL where your app is hosted (e.g., http://localhost:3000 for local development or https://yourdomain.com for production).
INTERNAL_API_KEY -- A secret key for internal API calls (try using openssl rand -hex 32 for a secure key)
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.

Update your .env file with the credentials:

MICROSOFT_CLIENT_ID=your_client_id_here
MICROSOFT_CLIENT_SECRET=your_client_secret_here

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

If this is the case you must also set the ECONOMY_LLM_PROVIDER environment variable.

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.

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/watch/all

Watching for email updates

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

  "crons": [
    {
      "path": "/api/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.

Docker Build Instructions

When building the Docker image, you must specify your NEXT_PUBLIC_BASE_URL as a build argument. This is because Next.js embeds NEXT_PUBLIC_* variables at build time, not runtime.

Building the Docker image

# For production with your custom domain
docker build \
  --build-arg NEXT_PUBLIC_BASE_URL="https://your-domain.com" \
  -t inbox-zero \
  -f docker/Dockerfile.prod .

# For local development (default)
docker build -t inbox-zero -f docker/Dockerfile.prod .

Running the container

After building, run the container with your runtime secrets:

docker run -p 3000:3000 \
  -e DATABASE_URL="your-database-url" \
  -e AUTH_SECRET="your-auth-secret" \
  -e GOOGLE_CLIENT_ID="your-google-client-id" \
  -e GOOGLE_CLIENT_SECRET="your-google-client-secret" \
  # ... other runtime environment variables
  inbox-zero

Important: If you need to change NEXT_PUBLIC_BASE_URL, you must rebuild the Docker image. It cannot be changed at runtime.

For more detailed Docker build instructions and security considerations, see docker/DOCKER_BUILD_GUIDE.md.
