Comparison
Datadog is a full observability platform for enterprise teams. UptimeSignal is focused uptime monitoring at a fraction of the cost. Different tools for different needs and budgets.
Datadog is a comprehensive cloud monitoring and observability platform. Founded in 2010, it has grown into an enterprise standard for full-stack visibility, offering APM, log management, infrastructure monitoring, and more.
Datadog is designed for engineering teams at medium-to-large companies who need unified observability across complex, distributed systems. It's particularly popular with companies running microservices on Kubernetes, multi-cloud deployments, and organizations with dedicated DevOps or SRE teams.
Datadog uses usage-based pricing across multiple products. Costs can escalate quickly as your infrastructure grows.
If you only need to know when endpoints go down, you don't need Datadog's full observability stack. UptimeSignal at $15/month provides unlimited HTTP monitors—that's a fraction of what Datadog's synthetic monitoring alone would cost.
Datadog requires installing agents on your infrastructure, configuring integrations, and setting up dashboards. UptimeSignal requires nothing—enter a URL and you're monitoring in 60 seconds. No agents, no CLI, no YAML.
Datadog's usage-based pricing can lead to unexpected bills when traffic spikes. UptimeSignal's flat pricing means you always know what you'll pay. Scale up your monitors without scaling up your costs.
Datadog doesn't offer status pages. UptimeSignal includes unlimited public status pages at no extra cost—share uptime information with customers without paying for another tool.
Many teams already using Datadog add UptimeSignal for external uptime monitoring to avoid inflating their Datadog synthetic monitoring costs:
This approach gives you comprehensive observability internally with Datadog while keeping external uptime monitoring costs predictable at $15/month.
UptimeSignal is a focused uptime monitoring tool at $15/month flat for unlimited monitors. Datadog is a comprehensive observability platform covering APM, logs, traces, infrastructure monitoring, and synthetic monitoring. Choose UptimeSignal for simple HTTP monitoring, Datadog when you need full-stack observability.
UptimeSignal costs $15/month flat for unlimited monitors. Datadog's synthetic monitoring alone starts around $5 per 10,000 test runs, plus base platform costs. A typical Datadog deployment can cost $100-$1000s/month. For focused uptime monitoring, UptimeSignal is 10-100x cheaper.
Yes, many teams use both. Datadog handles internal observability (APM, logs, traces, infrastructure), while UptimeSignal handles external uptime monitoring at a fraction of the cost. This gives you comprehensive coverage without inflating your Datadog bill.
No, Datadog does not offer public status pages. UptimeSignal includes unlimited free status pages that you can share with customers. If you use Datadog and need status pages, you'd need a separate tool.
UptimeSignal is designed for developers and small-to-medium teams who need reliable uptime monitoring without enterprise complexity. If you need full observability with APM, distributed tracing, and 750+ integrations, Datadog is more appropriate. If you just need HTTP monitoring, UptimeSignal is sufficient.
UptimeSignal takes about 60 seconds—enter a URL and you're monitoring. Datadog requires installing agents, configuring integrations, setting up dashboards, and often involves days or weeks of implementation for a full deployment.
$15/month for unlimited monitors. No agents, no surprises.
