n8n Workflow: Claude GMB One-Page Site Generator & Publisher

Turn a business brief into a live, one-page website—then publish it to a Hostinger subdomain

This n8n workflow uses a Chat UI with OpenRouter (Claude Sonnet) to generate and iteratively edit a complete one-page local business website, serve an instant HTML preview, and publish the approved version to a Hostinger subdomain—while archiving every version to n8n Data Table, Google Drive, and Google Sheets.

What this workflow does

• Intake + routing: Receives a message in the n8n Chat UI, then uses OpenRouter (Claude Sonnet) to extract a business brief and decide whether to respond, build the site, or publish.
• Generate or edit index.html: On build/update, it loads the latest saved HTML for the current chat session and asks Claude Sonnet to create a complete index.html (or apply edits).
• Clean HTML, create preview, version it: Cleans the model output into raw HTML, generates a preview URL, and saves a new version (with status) to an n8n Data Table.
• Archive + logging: Stores the generated HTML in Google Drive and appends a run log (including the preview URL and Drive link) to Google Sheets.
• Live preview endpoint: Serves GET /preview/:siteId by loading the latest HTML from the Data Table, injecting a fixed “Publish Live/Update Website” bar, and returning the page as text/html.
• Publish to Hostinger: Handles POST /publish/:siteId by creating a Hostinger subdomain via API, uploading HTML via FTP, updating the Data Table to “deployed” with the live URL, and returning a JSON confirmation.

Use cases

• Fast creation of one-page websites for local services (e.g., clinics, salons, contractors) with iterative approvals.
• SaaS operations teams generating landing pages from customer briefs with a transparent preview → publish flow.
• Automation engineers needing versioned HTML publishing with audit logs across Data Table, Drive, and Sheets.

Technical details
