Connecting Hasura to a Supabase Postgres Database


This guide explains how to connect a new or existing Supabase Postgres database to a Hasura instance, either on Hasura Cloud or via one of our self-hosted solutions. If you're exploring Supabase Postgres and are interested in migrating an existing Postgres database - such as from Heroku - check out their docs before continuing below.


If you plan on using Hasura Cloud, which we recommend, follow steps 1 and 2 below. If you're self-hosting a Hasura instance and already have a project running, skip to step 3.

Step 1: Sign up or log in to Hasura Cloud

Navigate to Hasura Cloud and sign up or log in.

Step 2: Create a Hasura Cloud project

On the Hasura Cloud dashboard, create a new project:

Create Hasura Cloud project

After the project is initialized successfully, click on Launch Console to open the Hasura Console in your browser.

On the Hasura Console, navigate to the Data tab and choose Connect Existing Database. Hasura will prompt you for a Postgres Database URL. We'll create this in the next step and then come back here.

Step 3: Create a Postgres DB on Supabase

Log into Supabase using your GitHub login.

From your dashboard, click New project:

Create a new project with Supabase

If you don't already have an organization within Supabase, you'll need to create a one. Click New organization:

Create a new organization with Supabase

Fill in a name and click Create organization:

Name your organization with Supabase

After creating your organization, you'll be presented with the Create a new project view. Fill in the necessary information and click Create new project:

Confirm project creation

You'll be redirected to your project's dashboard. After a few minutes, your database should be provisioned. You'll know you're ready once your dashboard changes from this:

Dashboard as project is being provisioned

To this:

Congratulations! You've now created a Postgres instance on Supabase which you can use with Hasura GraphQL Engine. Follow the steps below to connect it to Hasura.

Step 4: Get the database connection URL

The structure of the database connection URL looks as follows:


From your database's dashboard, click the Settings icon on the side navigation:

From dashboard, choose settings on the left-hand side

Choose Database:

Database information within the settings view

Then scroll down to find the Connection string section. Select the URI option and copy the string:

Grab the PG db connection string

You'll need to replace [YOUR-PASSWORD] with your project's password.

Step 5: Finish connecting the database

Back on the Hasura Console, enter the database URI that we retrieved in the previous step:

Connect the database on Hasura Console

Then click Connect Database.


For security reasons, it is recommended to set database URLs as env vars and using the env vars to connect to the databases in place of the raw database URLs.

Voilà. You are ready to start developing.
