Why it matters
We look beyond stars: what problem it solves, whether it creates real utility, and what makes its approach worth noticing.
Problem
Individuals or small teams holding multiple domains often face the pain points of scattered registrars, expired SSL certificates, and unnoticed DNS changes. This project provides a centralized hub to address them.
Practical value
It automatically fetches asset data like SSL, DNS, hosts, and IPs, providing expiration reminders and webhook notifications with low maintenance overhead and self-hosting support.
Innovation / differentiation
It functions essentially as an aggregated dashboard and monitoring tool for domain assets, relying on conventional API polling and status checks without architectural breakthroughs.
Leverage potential
Integration via REST/GraphQL API, Prometheus, and RSS makes it relatively straightforward to incorporate domain monitoring data into existing operations or notification workflows.
Why now
Domain management is an ongoing, routine requirement without a specific surge trigger.
Community activity
In the last 90 days there were 6 new issues and 19 pull requests; the bounded issue/PR samples include 5 issue authors and 4 PR contributors, with 1 releases.
Maintainer responsiveness
The 6-issue window sample had a 100% close rate, and the 19-pull-request sample had a 100% merge rate. Maintainer-comment observations covered only 100% of that issue sample, so response rate and first-response speed are not reported.
Key highlights
- Collect domain data such as SSL, registrar, hosting, IP, subdomains, and DNS
- Monitor expirations, configuration changes, website health, and performance with notifications
- Track purchase prices, renewal costs, tags, and related resources
Quick start
How it is installed, how hard it is, and where to start.
Where it runs
Docker
Difficulty
Medium — some setup needed
- 01Prepare a host with Docker and the ability to run a PostgreSQL container.
- 02Use the documented installer or
docker-compose.ymland configure the database connection and other environment variables. - 03Start the services, open the web interface, add domains, and configure expiration or change notifications.
Best for
- Teams that want data on their own servers
- Developers who want to try it on their machine
- People who prefer Docker deploys
More about it
Domain Locker provides one web interface for maintaining a portfolio of domain names and automatically collecting related SSL, registrar, host, IP, subdomain, and DNS data. It continuously monitors domain state and upcoming expirations, keeps configuration history and website health data, and adds cost tracking, tags, notifications, import/export, and API access. The project offers both a hosted option and Docker self-hosting, which is useful for individuals or teams managing domains spread across multiple registrars and providers.
