# Hosting n8n using huggingface space

If you don't have a cloud instance or domain, self hosting n8n may be a bit difficult.
This repository is a template for hosting n8n using huggingface space.

## Using Supabase for database

According to [huggingface space documentation](https://huggingface.co/docs/hub/en/spaces-overview#lifecycle-management),
Space will "go to sleep" and stop executing after a period of time if unused.
To avoid this, we can use [Supabase](https://supabase.com/) for the database.

1. Sign up for a free account at <https://supabase.com/dashboard/sign-up>
2. Create a new project and fill the form. Save the database password for later use.

3. View the database connection info by click the **Connect** button on the top left nav bar.

4. Select **SQLAlchemy** as Connection String and find the **Transaction pooler** section.

5. Save the connection info for later use: host, port, user, dbname.

## Deploying n8n using huggingface space

Huggingface space provide a free tier with 16GB RAM, 2 CPU cores and 50GB of
(not persistent) disk space. This is enough for hosting n8n.

| **Hardware** | **GPU Memory** | **CPU** | **Memory** | **Disk** | **Hourly Price** |
| ------------ | -------------- | ------- | ---------- | -------- | ---------------- |
| CPU Basic    | -              | 2 vCPU  | 16 GB      | 50 GB    | Free!            |

Using this space to duplicate and deploy n8n in the easy way.

1. Sign up for a free account at <https://huggingface.co/join> and pick a profile name.
   `tomowang` is the profile in <https://huggingface.co/tomowang> as an example.
   Remember the profile name for later use.

2. Access <https://huggingface.co/spaces/tomowang/n8n> and click the menu drop
   down in top right corner and select **Duplicate this space**.

3. Fill or change the variable and secrets in pop-up form and click **Duplicate**.

   ![hf space env](images/hf_space_variables.png)

   | **Variable**             | **Value**                                                |
   | ------------------------ | -------------------------------------------------------- |
   | `DB_POSTGRESDB_PASSWORD` | supabase db password                                     |
   | `DB_POSTGRESDB_USER`     | supabase db connection `user`                            |
   | `DB_POSTGRESDB_HOST`     | supabase db connection `host`                            |
   | `DB_POSTGRESDB_PORT`     | 6543                                                     |
   | `N8N_ENCRYPTION_KEY`     | Random string. Use `openssl rand -base64 32` to generate |
   | `WEBHOOK_URL`            | Example `https://<profile>-n8n.hf.space/`                |
   | `N8N_EDITOR_BASE_URL`    | Example `https://<profile>-n8n.hf.space/`                |
   | `GENERIC_TIMEZONE`       | Config by requirement                                    |
   | `TZ`                     | Config by requirement                                    |

4. Click **Duplicate Space** and wait for the deployment to finish. You can
   find the logs as following

   ![hf space deploy start](images/hf_space_deploy_start.png)

5. Once the deployment is finished, you can find the URL as configured in the
   `N8N_EDITOR_BASE_URL` variable.

   ![hf space deploy done](images/hf_space_deploy_done.png)

Now you can access n8n using the URL.

> n8n use [helmet](https://github.com/helmetjs/helmet) for security headers.
> In production mode, it will set `X-Frame-Options` to `sameorigin`, which causes
