[FREE] Domain Monitor - Self-Hosted Domain Expiration Tracking System (PHP 8.1+)

HosteroidHosteroid Hosting Provider
in Technical

Hey everyone!
I wanted to share a small open-source project we’ve built at Hosteroid — a self-hosted Domain Monitor that helps you track domain expirations and stay on top of renewals.

🔗 GitHub: https://github.com/Hosteroid/domain-monitor

💡 What it does
Monitors and lists domains with expiry dates.
Sends email notifications before expiration.
Supports cron automation for daily checks.
Works with any standard WHOIS-compatible TLD.
Clean and simple PHP-based interface.

🧰 Requirements
PHP 8.1+
MariaDB or MySQL
Web server (Apache / Nginx)
Cron for periodic checks

🚀 Features
Self-hosted — your data stays on your server.
Easy setup via SQL import and config file.
Modern, lightweight UI.
CLI and browser access for flexibility.

🧩 Why we built it
We needed a simple internal tool to monitor domains we manage and realized others might find it useful too. No SaaS, no subscriptions — just a clean, open-source PHP app you can host yourself.

🧪 Demo & Contributions
Feel free to test it out or fork it!
Issues, feature requests, and PRs are very welcome.

Would love to hear your thoughts, ideas, or improvements!

    I’m currently using DomainMOD, but I’m not completely satisfied with it.
    Your project looks much more interesting, and I’m going to give it a try right away.
    I already have a few ideas for new features in mind.

    Thank you so much for sharing this project with us — you’re not only a great hosting provider but also a great developer!

    It’s OK if you disagree with me. I can’t force you to be right!
    IPv4: 32 bits of stress. IPv6: 128 bits of... well, more stress... Have anyone seen my subnet?

    Looks nice! I enjoyed skimming the domain-monitor README.md, which seems thorough. Interesting that it is MVC. Maybe I will try installing and running. Thanks for making domain-monitor open source! <3

    I hope everyone gets the servers they want!

    Is there a comprehensive, open source, PHP (can use with Lynx browser), client and KVM VPS control panel into which domain-monitor integrates? :)

    I hope everyone gets the servers they want!

    @nwnuyhs Thanks! Looks great, but, if I understand correctly, it's not a client and KVM VPS control panel. I'm looking for client sign-up, product selection, support, KVM VPS creation, plus simple active service monitoring. Hope you have a good day! Best wishes!

    Pushed many more features and bug fixes, major one demo is now restriced not global anymore and you can use it free of charge to monitor your own domains, which means other users cannot see anymore your domains or notification groups. <3
