n8n Domain Availability Monitor: Porkbun + Sheets Alerts

Watch your target domains—automatically alerted the moment they become available

This n8n Domain Availability Monitor checks domain availability through the Porkbun API on a schedule, then sends Gmail and Discord alerts when a domain you’re tracking becomes available—while updating your Google Sheets list in real time.

What this workflow does

• Scheduled monitoring: Runs on a configured interval using a scheduled trigger.
• Reads targets from Google Sheets: Loads domains from a worksheet where isAvailable is set to no (expect Domain and isAvailable columns).
• Checks availability via Porkbun: For each domain, calls the Porkbun API and retrieves availability and pricing details.
• Sends alerts on availability: If Porkbun reports the domain is available, it sends an HTML email via Gmail including pricing and a Porkbun checkout link.
• Notifies on Discord: Posts a message with the domain and pricing to your selected server/channel.
• Updates Google Sheets: Sets isAvailable to yes, waits 10 seconds, and continues to the next domain.

Use cases

• SaaS operators tracking brand domains and catching availability windows.
• Automation engineers monitoring multiple domains and getting instant Gmail/Discord alerts.
• Startup founders keeping a shortlist of domains in Google Sheets and responding quickly when Porkbun reports them as available.

Technical details

• Integrations: Porkbun API, Google Sheets, Gmail, and Discord.
• Workflow nodes used: if, set, code, gmail, slack, webhook (per the workflow’s setup).
