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. [ Start monitoring ](https://ohdear.app/register) 10 day free trial No credit card required - Bitmovin - HBO Nordic - Obsidian - Laravel - Fathom Analytics - PHP 8 - Stanford University - Takeaway.com - IGN - VRT NWS - spatie 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 ### 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. ### 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. ### 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. ## Oh Dear compared with Datadog | | | Datadog | |---|---|---| | Uptime monitoring? | Yes | Yes | | Ping monitoring? | Yes | Yes | | TCP port monitoring? | Yes | Yes | | Performance monitoring? | Yes | Yes | | Lighthouse audits? | Yes | Partial | | Certificate health (SSL/TLS)? | Yes | Yes | | Broken links & mixed content? | Yes | No | | Sitemap monitoring? | Yes | No | | DNS monitoring? | Yes | Yes | | DNS blocklist monitoring? | Yes | No | | Domain expiry monitoring? | Yes | No | | Scheduled-task / cron? | Yes | Partial | | Application health checks? | Yes | Yes | | Port scanning? | Yes | No | | AI-powered checks? | Yes | Partial | | Notifications & integrations? | Yes | Yes | | Status pages? | Yes | Yes | | Single sign-on (SSO)? | Yes | Yes | | Unlimited users & destinations? | Yes | Usage-based | | Uptime check interval? | 1 minute | 1 minute | | Incident management / on-call? | No | Yes | | Entry price? | $17 | Usage-based | Sourced from each vendor's docs · June 2026 [ Try 10 days for free ](https://ohdear.app/register) When Datadog is the better call ### Full observability platform Best if you already run Datadog for APM, logs, metrics and infrastructure and want synthetic checks alongside them, with usage-based billing you are happy to manage. ## Weighing other tools?

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. ### What does Oh Dear offer that Datadog doesn't? 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. ### How does pricing compare? 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. [See all other FAQ items →](https://ohdear.app/docs/faq) ## Start monitoring instantly Start a no-strings-attached 10-day free trial.
