How is Oh Dear different from Datadog?

Datadog is the observability giant; uptime is one slice of the suite. Oh Dear takes a wider view: uptime plus SSL, DNS, full-site crawling, cron checks and Lighthouse, in one tool with one bill. Here's the honest comparison.

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 Datadog if you are already all-in on Datadog for APM, logs and infrastructure and want synthetic uptime in the same usage-billed platform.

What we have that Datadog doesn't

AI-powered monitoring

1. AI-powered monitoring

Describe a check in plain English and we run it. Datadog's AI can suggest tests, but it doesn't run natural-language checks against your pages.

Full site crawling

2. Full site crawling

We crawl your entire site for broken links, mixed content, and sitemap issues. Datadog tests the individual URLs and journeys you configure.

Simple, predictable pricing

3. Simple, predictable pricing

One flat price per site. Datadog Synthetics is usage-metered (a single 1-minute test already runs around $22/month) and spread across separately-billed products.

Frequently asked questions

Target rings Target rings

Datadog makes sense if you already run it for APM, logs, metrics and infrastructure and want synthetic uptime checks in the same platform, and you are comfortable with usage-based billing across many products.

Oh Dear includes natural-language AI checks, full site crawling for broken links and mixed content, sitemap monitoring, domain expiry, DNS blocklist and port scanning, all built in, with one flat per-site price instead of usage-metered tests spread across separate products.

Datadog Synthetics is usage-metered (a single 1-minute uptime test already runs around $22/month at list), with no meaningful free tier and most capabilities billed as separate products. Oh Dear starts at €10/month for 5 sites with everything included.
