Open-source domain manager that automatically monitors expirations, SSL, DNS, and sends alerts via multiple channels.
Core Features
- Auto-fetch domain data: SSL, hosts, registrars, IPs, DNS, subdomains
- Multi-channel notifications before expiration (email, webhook, Slack, Telegram, SMS)
- Rich analytics: uptime, performance, valuation, change history
- Multi-language, dark/light/custom themes
- Import/export, REST & GraphQL APIs
What It Can't Do
- •Self-hosting requires Docker and PostgreSQL; free online tier has domain limits; data accuracy depends on public Whois/DNS services.
Use Cases
- Manage multiple domains across different registrars and hosts
- Never miss a domain expiration again
- Monitor SSL certificate expiry and DNS changes for security
Domain Locker is an open-source tool that gives you complete visibility into your domain name portfolio. It automatically analyzes each domain, fetching SSL certificates, hosting info, registrar details, IPs, DNS records, and subdomains. You can monitor changes over time, receive configurable notifications (webhook, email, SMS, etc.) before expirations, and view rich analytics like uptime, performance, and valuation. Supports multi-language, custom themes, import/export, REST/GraphQL APIs, and easy self-hosting via Docker. Ideal for individuals and businesses managing multiple domains across different registrars.
