Domain Locker
Self-HostedSelf-hosted domain security tool to lock and monitor domain access
Overview
Domain Locker is a self-hosted domain security management tool built to safeguard your domain assets from unauthorized access or modifications. It enables locking domains to trusted IP ranges, monitoring DNS record changes in real-time, and setting up instant alerts for suspicious activities like unexpected transfer requests. Deployable via Docker containers for quick setup, it integrates with major domain registrars’ APIs (e.g., GoDaddy, Namecheap) to automate security workflows. With a centralized dashboard, you can manage multiple domains in one place, retaining full control over your domain security without relying on external SaaS providers.

Frequently Asked Questions
? Is Domain Locker hard to install?
No—Domain Locker uses Docker containers for deployment, so you can set it up with a single docker-compose command. You just need to configure API keys for your domain registrars and define trusted IP ranges in the settings.
? Is it a good alternative to proprietary domain lock tools?
Yes—unlike SaaS tools, Domain Locker lets you self-host all data, avoiding third-party access to your domain details. It also supports multiple registrars in one dashboard, which many proprietary tools don’t offer, making it ideal for managing domains across different providers.
? Is Domain Locker completely free?
Yes—Domain Locker is open-source software released under a permissive license (e.g., MIT), so it’s free to use, modify, and self-host without any subscription fees or hidden costs.
