Advantages of Self-Hosting for AI
By self-hosting n8n on your own VPS, you have no 'workflow execution' limits like cloud plans, making it much more cost-effective for heavy Generative AI applications.
API Security Warning
Ensure your n8n domain uses HTTPS (SSL) before entering any sensitive API Keys (OpenAI/Stripe) to prevent data theft.

Step by Step
Subscribing to Hostinger VPS and Selecting the n8n Template
- Visit the Hostinger website and choose a VPS plan (KVM 2 or higher is recommended).
- Complete the payment process and log in to your Hostinger Dashboard.
- Click the 'Setup' button on your newly purchased VPS plan.
- Select the server 'Location' closest to your target audience (e.g., Singapore).
- Choose 'Select OS' and search for the 'Applications' category.
- Select the 'n8n' template (usually powered by Docker on Ubuntu).
- Enter a strong 'Server Password' and save it for future reference.
- Click 'Finish Setup' and wait until the server status shows as 'Running'.
Configuring Domain and SSL for n8n
- Copy your VPS 'IP Address' from the Hostinger Dashboard.
- Go to the 'Domain' or DNS Management section where your domain is registered.
- Add a new 'A Record': Enter '@' or a subdomain (e.g., 'n8n') and paste the 'IP Address'.
- Return to the Hostinger VPS Dashboard and click on the 'Settings' tab.
- Look for the 'Panel Access' section or click the 'Login' button for the administrative panel provided in the template.
- Follow the on-screen instructions to enter your domain so the system can automatically generate an SSL (https) via Let's Encrypt.
Integrating Generative AI (OpenAI/Claude) in n8n
- Open your n8n dashboard and click 'Create New Workflow'.
- Press the '+' button, then search for and select the 'OpenAI' or 'Anthropic' (Claude) node.
- Within the node settings, click 'Create New Credential'.
- Paste the 'API Key' you obtained from the respective AI platform.
- Use the 'AI Agent' or 'Chain' node to combine the AI model with external data.
- Connect a 'Chat Trigger' node so you can interact with the AI directly through the n8n interface.
