How to Fix Data Loss in n8n on Render (Step-by-Step 100% Free Persistence Guide)

Have you deployed n8n on Render's free tier, only to find yourself greeted by the initial owner registration screen (Set up owner account) every single time you log in? This recurring issue is not a credential error or a multi-account flag. The root cause is that Render's free tier uses an ephemeral filesystem that deletes the default local SQLite database whenever the instance restarts or goes to sleep.

Why Your Data Gets Wiped on Render

By default, n8n attempts to save your workflows, credentials, and user data into an internal SQLite file. On Render's free tier web services, any file created locally within the container is automatically destroyed when the instance shuts down or restarts. To prevent your data from resetting every 15 minutes, you must connect an external PostgreSQL database, such as the one offered in Supabase's generous free tier.

Minimum System Requirements and Low-End PC Viability

Since all execution logic and data storage take place in the cloud, your local computer requirements are minimal:

• Local RAM: 1 GB or higher (just enough to run a web browser).
• Processor: Any legacy or modern CPU capable of opening web pages.
• Operating System: Windows, macOS, Linux, ChromeOS, or mobile devices.

Definitive Setup Guide (Hassle-Free)

Step 1: SUPABASE Configuration

1. Sign up at Supabase and follow the setup wizard to create a new free project and database.
2. To get your connection parameters, click the Connect button located at the top of your project dashboard to copy the technical details.
3. Use the retrieved details to map out the following 6 mandatory environment variables:
   • DB_TYPE (Always set to postgresdb)
   • DB_POSTGRESDB_HOST (Your host address provided by Supabase)
   • DB_POSTGRESDB_PORT (Standard port 5432)
   • DB_POSTGRESDB_DATABASE (Standard database name postgres)
   • DB_POSTGRESDB_USER (Standard database user postgres)
   • DB_POSTGRESDB_PASSWORD (The password you assigned when creating your database)
   • N8N_ENCRYPTION_KEY (A custom secret key created by you)

Step 2: RENDER Configuration

1. Log in to your dashboard at Render and open the Web Service created for n8n.
2. In the left sidebar menu, click directly on the key icon labeled Environment.
3. Click on Edit and then select + Add Variable.
4. Add your environment variables one by one using the designated KEY (variable name) and VALUE (variable content) fields:
   • KEY: DB_TYPE | VALUE: postgresdb
   • KEY: DB_POSTGRESDB_HOST | VALUE: your_supabase_host
   • KEY: DB_POSTGRESDB_PORT | VALUE: 5432
   • KEY: DB_POSTGRESDB_DATABASE | VALUE: postgres
   • KEY: DB_POSTGRESDB_USER | VALUE: postgres
   • KEY: DB_POSTGRESDB_PASSWORD | VALUE: your_password
   • KEY: N8N_ENCRYPTION_KEY | VALUE: your_secret_encryption_key
5. Once all variables are entered, click the SAVE AND DEPLOY button to save changes and restart the server.

Done! Once the service redeploys, n8n will store all your credentials and workflows permanently, solving the ephemeral database issue once and for all.
