Domain Locker vs Oh Dear

All-in-one tool for keeping track of your domain name portfolio

Track all your domain names in one place. Monitor expiry dates, DNS records, SSL certificates, WHOIS data, and hosting info. Get alerts before domains expire. Self-hosted, privacy-first, and built for developers and businesses managing multiple domains who are tired of checking registrar dashboards one by one.

Monitor your whole website, not just whether it's up

Oh Dear goes beyond basic uptime pings — it monitors SSL certificate expiry, broken links, DNS changes, scheduled tasks, and application health from one dashboard. Built by two developers from Antwerp as a hobby project in 2017, it's been self-funded and profitable ever since.
