Domain Locker

Domain Locker is a self-hostable web application for keeping complete visibility of your domain name portfolio in one place. It collects and enriches domain data (such as DNS, WHOIS, and SSL details), monitors for changes and expirations, and provides dashboards and analytics across your domains.

Key Features

• Centralized dashboard for domains, registrars/providers, and upcoming expirations
• Auto-fetched domain data including DNS records, WHOIS/registrar info, IPs, SSL certificates, and subdomains
• Change tracking and audit-style history for domain configuration updates
• Uptime and basic performance monitoring with configurable alerting
• Notifications via multiple channels including email and webhooks
• Import/export and programmatic access via REST and GraphQL APIs
• Portfolio metadata tracking (tags, notes, purchase price, renewal costs, valuation)

Use Cases

• Track and manage a personal or business domain portfolio across multiple registrars
• Get alerted before renewals and when DNS/SSL/WHOIS changes occur
• Monitor availability and health of sites tied to critical domains

Domain Locker is useful for individuals, agencies, and teams who want a single place to manage domain operations and reduce the risk of missed renewals or unnoticed configuration changes.
