Supabase

How to connect Supabase managed PostgreSQL to SimpleBackups using the connection string method.

Supabase is an open-source Firebase alternative built on PostgreSQL. To connect it to SimpleBackups, all you need is the database connection string from your Supabase project settings — no firewall configuration is required. This guide walks you through copying the string and creating your first backup.

Connecting your database

Step 1: Copy the connection string

1. Go to your Supabase project and click Settings, then Database.
2. Scroll down to the Connection string section and click URI.
3. Make sure you select the Direct connection string, not the Connection pooler (Transaction or Session) string. Backups must use the direct connection. Connection strings that route through the pooler may pass validation but will fail at backup time with a database connection error.
4. Click Copy.
5. Replace [YOUR-PASSWORD] in the copied string with your actual database password.

!Warning

Do not use the **Connection pooler** string (the one containing `pooler.supabase.com`). Backups require the **Direct connection** string (typically `db.[project-ref].supabase.co`). Using the pooler can pass connection validation but will cause backups to fail.

Step 2: Create a database backup in SimpleBackups

1. Select PostgreSQL as the database Type in SimpleBackups. If you do not see the connection string field, click Paste connection string instead.
2. Paste the full connection string you copied from Supabase.
3. Click Validate Connection, then configure your schedule and storage destination.

iNote

You can click **Download CA certificate** next to the **Copy** button in Supabase and add the certificate to SimpleBackups as shown below. This step is optional but recommended.
