How is Oh Dear different from Zabbix?

the quick verdict
Choose Oh Dear if you want uptime, SSL/TLS, DNS, full-site crawling, cron checks and Lighthouse in one place, with unlimited users and one predictable bill.
Choose Zabbix if you need deep, customisable infrastructure and network monitoring and have the ops team to run and tune a Zabbix server.

Frequently asked questions

Target rings Target rings

Zabbix is a good choice if you want open-source software you fully control and self-host, and you have the time and ops skills to install, configure, secure and maintain it. Choose it when control and zero licensing cost outweigh the setup and upkeep.

Oh Dear is fully hosted with nothing to run or maintain, and includes website-specific checks self-hosted tools lack out of the box: AI-powered checks, full-site broken-link and mixed-content crawling, sitemap monitoring, real Lighthouse audits and public status pages, all in one place.

The software is free, but you pay in servers, setup, upgrades, security patching and the engineering time to keep it running, plus the risk that your monitoring goes down together with your own infrastructure. Oh Dear runs independently of your stack from €10/month.
